XC & IB 3.2 overlapping siblings
Folks; I know I'm late to the game here but I just took my app for a compile under XC3.2 for the first time… A few NSString encoding loose ends OK but WHAMO my .xib files are hammered with ~100 errors (not warnings!) ".. This view overlaps one of its siblings. Overlapping sibling views are not supported on Mac OS X versions prior to 10.5. …" My base SDK is set to 10.6 and a deployment of 10.4. Everything was peachy under 10.5 and XC3.1 no such warnings or errors. Sooo does this mean I cannot use XC3.2 unless I fix all these issues? Some are buttons that lie on top of each other and are hidden or shown based on data. How does one avoid the overlapping error in this circumstance? Is there a compiler setting that might be helpful here? This is certainly not what I expected…. Thanks for all input!

Re: XC & IB 3.2 overlapping siblings
Nick; Hey thanks for the reply! Yes, I'm aware of the IB target setting. If you still want to target Tiger this is a BIG surprise that these are now treated as errors. The really big question for me is how do you deal with 2 buttons that lie one on top of the other but are never drawn at the same time (setHidden) Do you have to re-jigger everything because IB can't fathom that they might not be visible at the same time? Could you comment on this please - this is a potential real quagmire for me… Steve On Sep 10, 2009, at 10:15 AM, Nick Zitzmann wrote: On Sep 10, 2009, at 2:51 AM, Steve Cronin wrote: My base SDK is set to 10.6 and a deployment of 10.4.

Nib deployment targets are actually set in the nibs, not the project. If you still want to target Tiger, you should fix the errors, since overlapping views are hit-and-miss on Tiger. Alternately, if you want to switch to targeting Leopard, then you can do it by clicking on the info toolbar button in IB and switching the deployment target there.

Snow Leopard and Exchange access using ABAddressBook

Developing a Stand-Alone Service in Snow Leopard
Foks;
I'm trying to develop a stand alone service in Snow Leopard.
The issue I'm running into is how to update the system as I compile a
new version.
The pbs command shows that the bundle path is the one in my Release
Build folder
"pbs -dump_pboard"
{
NSBundleIdentifier = "com.myCompany.myService";
NSBundlePath = "/Volumes/myMacBookPro/Projects/XYZ/Code/
build/Release/MyService.service";
NSKeyEquivalent = {
};
NSMenuItem = {
default = MyService;
};
NSMessage = myService;
NSPortName = myServicePort;
NSSendTypes = (
NSStringPboardType,
NSRTFPboardType,
NSTabularTextPboardType
);
So when I recompile I do the following:
1) 'Uncheck' the item in the SysPref/Keyboard/Services list
2) Compile a new version
3) run "/System/Library/CoreServices/pbs"
4) 'Check' the item in the SysPref/Keyboard/Services list
5) Test the service by using the context menu (which is appearing at
the right time)
I have convinced myself that the only way to get Snow Leopard to
recognize the newer version of the service is to log out and back in.
This is tedious. Is there something I'm missing?
Steve

Re: Developing a Stand-Alone Service in Snow Leopard
Folks To clarify my initial problem statement: If I recompile and then issue a "pbs" and then invoke the service it continues to execute an earlier instance of the service -- NOT the freshly compiled instance…. This is easy to prove A set of followup questions on STAND-ALONE services 1) How do I programmatically 'check' the service in System Preferences/ Keyboard/Services? I offer the user the option of installing a service. If they elect to install it seems reasonable that they would want the service engaged. Is the only option to open the System Preferences at the pane? I offer the new shiny; the user says yeah let's use the new groovy stuff; An then I have to say "sorry I can't figure that out for you -- here's a window here's a whole bunch of scary looking text - give it your best shot… (seems pretty lame to me) 2) Since I offer the option to install, I offer the option to uninstall. Is it safe to do this? The .service bundle is marked as open by the system. Is it sufficient to do: if ([[NSFileManager defaultManager] removeFileAtPath:myServicePath handler:self]) NSUpdateDynamicServices(); Thanks for your time and consideration!

Interface Builder .xib deployment/development targets
Folks; I have an app with a 10.4 Deployment target. I have recently begun using XC 3.2 and IB 3.2 - spp compiles cleanly and all IB 'sibling' issues have been resolved.

I've not seen this before and do not see it on my development machines (debug or release) Reporting machine is MacBookPro5,1 - 10.5.8 I have set the app's IB Deployment Target to 10.4 and IB Development Target to IB 3.2 Is there any reason to NOT use IB Development Target of 3.2?

Static Analyzer and Core Foundation
Folks;
Alert - potential boneheaded-ness lies ahead - please be gentle.
I'll be the first to admit that I'm much happier in ObjC than C…
I thought I would try static analysis and see what turned up.
On the whole I must say I'm pleased but this one has me questioning my
basic understanding
if (![[NSFileManager defaultManager] fileExistsAtPath:thisPath]) {
…
41 } else {
42 MDItemRef mdi = MDItemCreate( nil, (CFStringRef)thisPath );
43 if ( mdi != nil ) {
44 CFDictionaryRef dictRef = MDItemCopyAttributes( mdi,
MDItemCopyAttributeNames(mdi));
…
CFRelease(dictRef);
} else {
… handle error
}
}
Static Analysis tells me I have a potential leak of object allocated
on line 44 -- that's all.
My questions are:
1) Why is there not a warning for the object allocated on line 42 -
mdi ?
2) Why is the CFRelease(dictRef) not sufficient?
Thank you for you patience!

Re: Static Analyzer and Core Foundation

I've adapted the code to accomodate your's and Chris' answer to
question 2.
Here's the entire method, which now shows not static analyzer issues
but I still would like to understand why not.
+ (NSDictionary *)metadataForFilePath:(NSString *)thisPath {
NSDictionary *md = [NSDictionary dictionary];
if (![[NSFileManager defaultManager] fileExistsAtPath:thisPath]) {
NSLog(@"file does not existl");
} else {
MDItemRef mdi = MDItemCreate( nil, (CFStringRef)thisPath );
if ( mdi != nil ) {
CFArrayRef arrayRef = MDItemCopyAttributeNames(mdi);
CFDictionaryRef dictRef = MDItemCopyAttributes( mdi,
arrayRef);
md = [NSDictionary
dictionaryWithDictionary:(NSDictionary *)dictRef];
CFRelease(dictRef);
CFRelease(arrayRef);
} else {
NSLog(@"mdi is nil");
}
}
return md;
}
Is this the 'best' this can be?
Thanks for helping me learn,

MutableDictionary setValue:forKeyPath - strange behavior
Folks;
I have recently converted to XC & IB 3.2
I've updated my project to be a 3.2 project using a baseSDK of 10.6
with deployment target of 10.4
I've run the static analyzer and have no analyzer issues as well as no
compiler nor IB warnings
I'm feeling good about this but now code that worked under Leopard is
no longer working.
I have an instance variable which is an NSMutableDictionary *
myBaseSettings
I run a method which steps thru the keys in a local NSDictionary
(sessionSettings) to possibly set some values into myBaseSettings
NSDictionary * sessionSettings = ...;
NSArray *values, *keys = [sessionSettings allKeys];
int dictCount = [keys count];
if (dictCount>0) {
values = [sessionSettings allValues];
NSString *thisKey, *thisValue;
for (i=0 ; i(NOTE: I use setValue:forKePath because the sessionSetting keys can be
dictionaries)
I get an exceptions thrown whenever thisKey is a normal 'key' (ie
"workPhone") but NOT when thisKey is a 'keyPath' (ie.
"nameDict.firstName")
'*** -[NSCFDictionary setObject:forKey:]: mutating method sent to
immutable object'
The key and value are both valid strings (verified using 'po' gdb)
It seems like somehow the instance variable is not being treated as an
NSMutableDictionary but why?
Thanks for any thoughts on this - I'm baffled!

Re: MutableDictionary setValue:forKeyPath - strange behavior

In order to answer your request, I've gone back through the code that
generates myBaseSettings
essentially it is:
NSMutableDictionary *localDict = [NSMutableDictionary
dictionaryWithCapacity:70];
[localDict setObject:[self generateInterestingValue1]
forKey:@"interestingKey"];
…
…
[self setMyBaseSettings:localDict];
where setMyBaseSettings is an old-school KVC setter method
- (void) ssetMyBaseSettings:(NSMutableDictionary *) newSettings {
if (myBaseSettings!= newSettings) {
[myBaseSettings release];
myBaseSettings = [newSettings retain];
}
}
Does this provide you the information you are looking for?

Re: MutableDictionary setValue:forKeyPath - strange behavior
Folks;
Thanks for all of the guidance! I have found the issue.
It turns out that [localDict copy] is what was being sent to the
setBaseSetting.
In dealing with the static analyzer's warnings I must have made this
change and then had failed to back it out…
MY BAD
Removed this and all is well again.
A tip of the hat to Kyle for immediately sending me in the right
direction.
Karl - darn fine point about the random nature of 'allKeys'
(this code has been working fine for months - but I will stop relying
on this 'side-effect')
Thank-you all

This is good.

There's an extra "s" in here… does this mean you didn't actually
copy/paste the setter from your code? Or maybe you're using a
synthesized @property(copy) getter but a manually implemented setter,
and because you have typo'd the setter method, the compiler is
synthesizing one for you instead?

Data Model Versions and -fetchRequestTemplateForName
Folks;
I have recently converted to XC & IB 3.2
I've updated my project to be a 3.2 project using a baseSDK of 10.6
with deployment target of 10.4
I have a Core Data model that I've been very happy with starting in
10.4 and continuing in 10.5..
In readying for the brave new world ahead I have added a 'version' to
the data model.
I see 2 xcdatamodel documents (app1 and app2) - they are the same at
this point
After bring the app up to the tools and project setting described
above I've begun testing the release product on Tiger, Leopard , and
Snow Leopard.
The following method worked fine on all 3 OSes before these changes
- (NSArray *) elementsByTemplate:(NSString *) templateName {
NSError *error = nil;
NSArray *results;
//moc is an instance variable for the managedObectContext
NSFetchRequest * fReq = [[[moc persistentStoreCoordinator]
managedObjectModel] fetchRequestTemplateForName:templateName];
@try { results = [moc executeFetchRequest:fReq error:&error]; }
@catch ( NSException *e ) { NSLog(@"(Template:%@) Caught %@: %@ \r
%@", templateName, [e name], [e reason], [e userInfo]); }
if ( error != nil) { NSLog(@"%@ - Caught %i: %@ info = %@",
NSStringFromSelector(_cmd), [error code], [error domain], [error
userInfo]); }
return ( (results==nil) ? [NSArray array] : results);
}
This fails on Tiger BUT continues to work normally on Leopard & Snow
Leopard.
fReg is NULL on Tiger (used to work fine on Tiger)
so the exception get caught with 'fetch request must have an entity)
[Yeah - so I do see that I should test for a null fetchRequest but
that's not the issue really!]
Is the model versioning the problem? Can I 'undo' that?
(I can't do a 'fetchRequestTemplatesByName' because that was
introduced in 10.5)
Is there something I can do or that I am overlooking?
I have backed the base SDK down to 10.5 (I can easily because I just
made that change to 10.6 and have no embedded 10.6 code as yet)
It still fails for Tiger.
I have also removed app2 from the xcdatamodeld bundle but this also
does not change the result.
I'm stumped on what to do to remedy this situation!
Thoughts?

App Crashing on a second AppleScript call
Folks; I have an app that receives AppleScript calls App passes Clang with no warnings; using XC 3.2 w/ 10.6SDK The call is made successfully and performs beautifully -- the first time!

Static Analyzer Question
Folks;
I have a Clang issue that is making me a little crazy.
I have a modestly complex Core Data application with several thousand
lines of code.
I've run Clang and at this point I have only one issue:
"…. Object with +0 retain counts returned to caller where a +1
(owning) retain count is expected"
this is shown at the end of a particular method.
The deal is that, over time, I have isolated this method and at this
moment there are NO methods which call it.
I cannot leave it like this - this isolation is a result of honing in
on the Clang issue...
A very common pattern for my application looks like this:
+ (NSString *) fooBar {
NSString *result = @"";
…..
if (x) {
result = @"1";
...
} else {
result = @"2";
}
return result;
}
Yes this is a class method - I use this pattern for both class and
instance methods.
This is the only method that Clang has an issue with…
Why does Clang believe that an 'owning retain count is expected' if
the method is never called?
Why is Clang picking on this one method which mirrors the mechanics of
so many others?
Any thoughts appreciated!
Steve

Gentlemen;
YES Bingo! + newWidgetID
I love how Cocoa can so drive you crazy and then when insight happens
it's often nearly painful in its elegance and simplicity…
Breathtaking sometimes….
Thank-you all,

I think this means the method has a name that by convention
indicates that it returns a reference the caller must release — i.e.
a prefix of "alloc" or "copy" or "mutableCopy"
+ (NSString *) fooBar {
NSString *result = @"";
…..
if (x) {
result = @"1";
...
} else {
result = @"2";
}
return result;
}
What's the actual name (not 'fooBar')?
Why does Clang believe that an 'owning retain count is expected' if
the method is never called?
Objective-C is a dynamic enough language that there is no way to
tell at compile time whether a method is reachable or not. Even if
that selector never appears in your code, it could be constructed at
runtime, or your code could load a plugin bundle that calls that
selector.

Re: Nib Loading Crash on Tiger only -- SOLVED (well made gone...)
Folks; I opened the .xib file in a text editor -searched for 'NSCoreUIImageRep' I found one instance (thankfully) and by 'reading' the text was able to determine that it was a matrix of 2 radio buttons. I removed the offending matrix and re-instantiated a fresh one. I monitored the .xib text as I re-sized it but was unable to generate a 'NSCoreUIImageRep' again. Compiled - deployed to Tiger -> works fine…. I dunno, my gut tells me that there is some way thru resize and cell spacing that IB 3.2 will use a 'NSCoreUIImageRep' but I gotta move on… Never was any IB warnings or errors…. Maybe this will help someone else… Thanks Graham and Kyle for the assist, Steve On Sep 30, 2009, at 1:56 AM, Kyle Sluder wrote: Check your IB compatibility settings.

OK thanks for the whack on the head…
I had managed to convince myself that there was something about the

No the problem was simply that there was a trailing space at the end

#include CommonStrings.txt - 'no such file' error
Folks; I have a dozen or so strings that I use over and over in various classes. So here's what I've done I have a CommonStrings.txt file added to the project. It looks like this: NSString *gLeftBracket =@"<"; NSString *gRightBracket =@">"; If I #include this file somewhere in the project then I can use 'extern' in the classes/methods where I need one of these strings. benefits: one place for definition type-ahead works - more efficient code construction costs: global-ness violates object-oriented principles committed global overhead for entire project that doesn't benefit every class however there are only ~20 of these there is no inherent 'read-only' support (which is what I would prefer) On the whole I'm inclined to accept the costs for the benefits! Is there a better way to achieve the goal in ObjC2? But here's my real question: It appears that I cannot put the one and only #include CommonStrings.txt just anywhere in the project. Some locations work fine others result in a 'CommonStrings.tx.' - no such file error. I'm just cutting and pasting the #include statement - so I'm not munging the statement. I cannot see any rhyme or reason on where it works and where it doesn't… Can someone clarify this for me?

Re: #include CommonStrings.txt - 'no such file' error
Folks; To Alexander: On the suggestion of using .m and .h files: If I use a single #include somewhere as shown below then I can within any method use extern NSString *gLeftBracket this allows other programmers to see immediately that it is defined elsewhere and I need not burden the entire class with the overhead #import the entire set of these common strings. It seems your approach require that I expose a given class to the entirety of the strings declared in the .m file. I believe my solution allows a more fine grained usage of these strings…. Please enlighten me if I am incorrect! To Fritz: Thank-you for opening my eyes on this! I had gotten it in my head that 'const' could not be used with objects!! This is very useful to me!

UIApplication terminate?

I don't want to pester the user with another alert or a dead screen for which the only reasonable action is [Home]. I'd like to shut the application down - I believe this is what the user will desire. How do I accomplish this? exit(0) seems a bit rude for my tastes but….

It has the key - I merely cited the outcomes based on two different setups that
I had constructed trying to understand what is going on...
I have the key and remain puzzled by the 'pointless' warning that is tossed off

Re: Why is compiler warning for +setKeys:triggerChangeNotificationsForDependentKey: ??
Graham;
Directly from the current Apple docs:Key-Value Observing Programming Guide
No mention of deprecation…
Registering Dependent Keys
It’s common that the value of one property of a class is dependent on the value
of another property of the same class. Key-value observing provides a
lightweight method of declaring these dependencies through the use of the class
method setKeys:triggerChangeNotificationsForDependentKey:.
The setKeys:triggerChangeNotificationsForDependentKey: class method specifies
an array of keys that will cause a change notification to be triggered for the
dependent key.
Consider the case of a method that returns a person’s full name by combining
the first and last names. The fullNameproperty is dependent on both the
firstName property and the lastName property. Anytime the value of firstName
orlastName changes, an observer notification must be sent for the fullName
property. The example in Listing 1 registers this dependency and implements the
accessor method for the fullName, firstName and lastName properties.
Listing 1 Registering a dependent key
+ (void)initialize {
[self setKeys:[NSArray arrayWithObjects:@"firstName",@"lastName",nil]
triggerChangeNotificationsForDependentKey:@"fullName"];
}

App won't launch in Debug but release product is fine
Folks; I need to pare back a project, remove some of the cruft. I copied the entire project directory and renamed the project and bundle identifier for now. I've removed various IB widgets as well as objC classes. I can now build without any issues in debug and release. If I double click the release build product it launches as expected. If I try and build and go on the debug build I see "Run" appear in the lower console log in XCode and then nothing. I've been over the build configurations (but I admit I weary). I have cleared XCode caches and done clean build - 10.6 - XC 3.2.2 Any thoughts on what would cause this? Thank you!

NSWindowController for Prefs XIB Question (Core Data involved)
Folks;
I have a feeling that this is an embarrassing one so try and go easy on me…
XC 3.2.2
I have a main nib that opens a window and that works fine.
I used to have an NSPanel in this nib to handle preferences.
I've decided it's a good idea to split the nib into two different nibs: the
main nib and a preferences nib.
I've looked over the Sketch project and used it as a model.
I've also read over the Document-Based App Overview FAQ
I've added a window nib to the project and then subclassed a NSWindowController.
I've made the xib's files owner this window controller
At this point I can get a simple empty window to open just fine.
However, I'm using CoreData and I want to pass the existing MOC to the pref
window:
I have added an array controller to the pref nib with its MOC set to files
owner's MOC in IB.
The controller manages an entity not a mutable dictionary.
MOC is a synthesized property of the PrefController (the windowController
mentioned above).
if (!prefPanelController) {
prefPanelController = [[PreferencesController alloc]
initWithWindowNibName:@"testPref"];
[prefPanelController setManagedObjectContext:[self
managedObjectContext]];
}
[prefPanelController showWindow:sender];
No window opens and I get a console error: Cannot perform operation without a
managed object context
Could someone give me the gentle head slap I need here?
Steve

Re: NSWindowController for Prefs XIB Question (Core Data involved)
Folks;
This one is driving me mad!
I'm trying to bust up an overly complicated xib into 2 xibs - the main xib and
a preference xib
I've started completely over trying to implement a pref xib -- no CoreData just
bare bones….
I have created a brand new subclass of NSWindowController: Pref2Controller
there is not a single line of code in this object nor any instance
variables.
I have created a brand new xib file: ptest
XCode creates the xib with a FilesOwner, FirstResponder, Application,
and Window (set to releaseOnClose and visibleAtLaunch)
I have set the FilesOwner to be an instance of Pref2Controller (using IB)
I have set the window outlet of the FilesOwner to point to the NSWindow object
(using IB)
These two are the only changes I've made to ptest.xib
When I use this code in the appDelegate:
- (IBAction) configure:(id)sender {
if (!prefPanelController) {
prefPanelController = [[Pref2Controller alloc]
initWithWindowNibName:@"ptest"];
}
[prefPanelController showWindow:sender];
}
The new ptest.xib window will open once but never again if I close it.
this is true regardless of whether I set the window to releaseOnClose
or not
this is also true regardless of whether I have hooked up the window
outlet or not
logging [pController window] shows (null) regardless of whether
I have outlet assigned or not
as well as regardless of whether prefPanelController already
exists or has just been alloc'ed and init'ed..
What I am just not understanding here?
Please?

Re: NSWindowController for Prefs XIB Question (Core Data involved) - Solved
Folks;
I have figured at least part of this out.
My PrefsController had an instance variable that was of a class from the Core
Data Model.
Since the MOC was not available until after the initWithWindow, anything
derived from NSManagedObject is not valid.
Once I removed this instance variable the window now now opens.
Hopefully this is helpful to someone else….

Multiple copies of an application installed
Folks; I've found through field testing that some of my customers are keeping several copies of my application on their computer. At various points in the usage, it is possible to launch the application using AppleScript as well as by invocations of -launchAppWithBundleIdentifier: However, when there are stale versions of an application around these do not launch the appropriate application. NSWorkspace does not appear to handle the notion that there might be more than one.. The return of absolutePathForAppBundleWithIdentifier is a NSString! How do other folks handle this situation? Ideally I would like to offer a list of the applications and inform the user of the unexpected consequences of this "collection"… Any thoughts appreciated.

'ditto' troubles
Folks; This is a Mac application. I have a helper app that I want to transport inside of a larger app (Mother) At the user's discretion I want to deploy the helper app The helper app CAN be called by AppleScript. In order to help with Mother's file size and inadvertent calling of Helper (when not yet deployed) I want to do is compress the app inside of the mother application. When the user asks for it I will decompress Helper and deploy into the local file system. I have all of this working including a build step that compresses the appropriate release version of Helper (/usr/bin/ditto -c -k --sequesterRsrc --keepParent) At the time the user requests I initiate an NSTask and deploy: NSTask *unzipTask=[[NSTask alloc] init]; [unzipTask setLaunchPath:@"/usr/bin/ditto"]; [unzipTask setArguments:[NSArray arrayWithObjects:@"-x",@"-k",sourcePath,targetPath,nil]]; The problem is that the deployed Helper file has the 'X' icon and displays the "application is damaged.." message. If I take the Helper.zip file from the 'contents' and manually double click it then the decompression works fine…. I'm so close and just I can't see what's stopping this deployment. Is there a ditto flag I need to set that I'm not seeing? Any thoughts appreciated!

Improving the User Experience when Installing a Snow Leopard Service
Folks; I'm a big fan of Snow Leopard's revised support for Services. In fact my application has a service that I would like most of my customers to use. What I have found from watching test subjects install my software is that many folks stumble on enabling the service. I understand that user needs to be in charge but ... What I'm looking for here is if anyone on this list has encountered these issues and has developed improved experiences for the user. My initialization process 1) creates the user 'Services' directory if required 2) installs the XYZ.service file into this 'Services' directory 3) calls NSUpdateDynamicServices() so the user's view is updated 4) calls NSWorkspace with an 'openFile' to get the Keyboard pane open @"/System/Library/PreferencePanes/Keyboard.prefPane" At this point all the user has to do is check the checkbox for the XYZ Service (it's a Text service) The issues that I've observed are: The prefpane does not initially necessarily open to the 'shortcuts' tabView The 'Services' item is not selected in the source list The 'Text' section is far down out of view and the order of the section is not alphabetic so the user is confused where to find this section. Is there a Cocoa way to remedy any of these that does not involve SystemEvents? mainly 'cause using 'System Events' cascades a whole new 'get the user to check the checkbox' activity….. All in all getting the user to simply check this checkbox makes for a really bumpy "out-of-box" experience for my new customers….

Improving the User Experience for First Use of Downloadable Software

Re: Improving the User Experience for First Use of Downloadable Software
Folks; Thanks for the thoughts on this matter! I think Matt raises an great point about hijacking on subsequent launches. Personally I'm mistrustful of installers.. why does a simple application need to go mucking around on my system? why is this application different than all the other 'drag-n-drop' applications? I think it creates another barrier to installation - another excuse for the customer to bail... And it is yet more code to maintain -- for what benefit?

Re: Improving the User Experience for First Use of Downloadable Software
Nick; Sorry I created the wrong impression there. Of course I understand that there are 'things to be done' but Joe Consumer doesn't necessarily know this... Furthermore the installer don't make it clear what these things are nor why they should have to be installed now (while the customer is still just trying to figure out if they even want to use the software) If they want the bells and whistles then the application should provide a way to add these later… Installers are 'intimidating' and another reason to abandon the fragile 'investigation' impulse a the potential customer… I'm on a tear to reduce these reasons for abandoning…. My research shows if folks actually install and try my program - they tend to buy it!

NSTableViewDropAbove visual remnant
Folks; I have a tableView which is working pretty handily. I support a form of import by dropping a text file on it. The backing arrayController returns an NSTableViewDropAbove for UI feedback purposes. (the row the file is dropped on (or above) doesn't actually matter) I chose NSTableViewDropAbove because DropOn might cause some to feel that a replacement would occur…. When I have complete the import process I call rearrangeObjects and all is well there is a bound filter predicate in the windowController EXCEPT the targetting indicator in the tableView remains visible… How do I clear this?

Dragging text between NSTextFields - A 'source' question
Folks;
I want to allow users to drag selected text between text fields.
I have subclasses NSTextField and implemented:
- (void)awakeFromNib { [self registerForDraggedTypes:[NSArray
arrayWithObject:NSStringPboardType]];}
- (unsigned int)draggingEntered:(id )sender { ...
- (BOOL)performDragOperation:(id )sender { ...
So I have the dragging part working just fine. But what I really want
is - NSDragOperationMove
The documents state that I should implement the
NSDraggingSourceProtocol method:
- (void)draggedImage:(NSImage *)anImage endedAt:(NSPoint)aPoint
operation:(NSDragOperation)operation
the discussion states:
This method is invoked after the dragged image (anImage) has been
released and the dragging destination has been given a chance to
operate on the data it represents. This method provides the source
object with an opportunity to respond to either a successful or a
failed dragging session. For example, if you are moving data from one
location to another, you could use this method to make the source data
disappear from its previous location, if the dragging session is
successful, or reset itself to its previous state, in the event of a
failure.
I have implemented this method in the subclass but it is never called!
What am I overlooking?
I did try adding to the .h @inteface declaration
but it didn't change anything.
Thanks for any help,
Steve

Approaches for this Matching Problem?
Folks;
I would like to solicit feedback on the best approach to solve this
problem: "phrase contains any word in set {a,b,c...}"
I have a user supplied phrase (usually 3-5 words; max of 10 words) ->
thePhrase
The user may provide any random phrase...
I also have a user managed array of words (somewhere around 250 words)
-> theTags
Currently these are stored as records in a Core Data entity.
This set of tags is fairly stable but is nonetheless managed by the user
I want the fastest means of determining if thePhrase contains ANY
member of theTags.
Position and frequency are not important. If ANY Tag is found the
'evaluation' can stop immediately.
method signature proposal - (BOOL) containsAnyTag:(NSString *)
thePhrase;
[NOTE: I may run this evalution several times in succession on
different phrases so, for now, the set of Tags is already setup as an
instance variable]
I am open to considering all options. Speed is THE top priority.
Code complexity is a far distant second.
Seems like a job for regex but I'm a total newbie there and since I
don't care about actual location nor frequency maybe it is NOT a job
for regex..
Seems like there could be many ways to proceed but I hoping somebody
might share some experience or insight.
Thank-You,
Steve

Re: Approaches for this Matching Problem?
Ken & Jerry;
Thanks for the quick response!
So I've been pondering and testing...
1) Why would I have to bust up/loop on thePhrase? This makes me face
Jerry's issue of a universal solution for breaking on words.
Just on general principal what would that solution be?
[thePhrase componentsSeparatedByString:@" "] sure is easy, fast and
effective for most of the folks who are going to pay for indie
software
But what is the right solution??
Seems like a common enough problem that there should be a well-
defined, easily obtained, well-documented answer
BUT in my case I don't care where, what word or how often - I just
want to know IF a tag occurs in thePhrase!!
thePhrase = 8 words
theTags = 150 words
the code below: 0.001 sec on 2Ghz MacBook -- Yeeoowssah!
-- added benefits beyond spec
-easy code to understand - not prone to error
-Search and Comparison options allow for easily implemented
flexibility - case-sensitivity; anchored, etc..
- (BOOL) containsTag:(NSString *)thePhrase {
BOOL tagFound = NO;
NSString *tag;
NSEnumerator *tagEnum = [tags objectEnumerator]; //tags is an NSSet
instance variable built from Core Data
while ((tag=[tagEnum nextObject])!=nil) {
if ([thePhrase rangeOfString:tag
options:NSCaseInsensitiveSearch].location!=NSNotFound) {
tagFound = YES; break;
}
}
return tagFound;
}
Thanks for making life good!

Re: Approaches for this Matching Problem?
Ken;
Thanks as always for a thought-provoking and thorough response!
1) I haven't given up on those Tiger users yet...
2) I don't see how looping on the 'words' in thePhrase would change
the 'ham' issue you raise - it would still match either on the word or
the phrase.
Am I missing something?
3) The actual tags in this particular context are extensive enough
that this 'ham-confusion' is pretty unlikely and could be easily
remedied by the user's management of the tag list... [e.g. service,
management, institute] -- I know there remains the root forms issue
but let's not drag that issue in here

Then you shouldn't refer to "words". If you just care if any of a
set of strings appear in a given string, that's a different question.
If one of your tags is "ham", do you want it to match a phrase
containing "shame"?
- (BOOL) containsTag:(NSString *)thePhrase {
BOOL tagFound = NO;
NSString *tag;
NSEnumerator *tagEnum = [tags objectEnumerator]; //tags is an
NSSet instance variable built from Core Data
while ((tag=[tagEnum nextObject])!=nil) {
if ([thePhrase rangeOfString:tag
options:NSCaseInsensitiveSearch].location!=NSNotFound) {
tagFound = YES; break;
}
}
return tagFound;
}
If you can target Leopard or later, you can simplify this even more
by using "for (NSString* tag in tags) ...". It's more efficient, too.
Regards,
Ken

Sorting on a table view of a managed object - debugger throws exception
Folks; 10.5.7 - 10.5 SDK - target 10.4 I have a managed core data entity working pretty nicely. I can display values in a tableView blah-blah Clicking on table column headers does as expected IN RELEASE versions for both Tiger and Leopard. However, in the debugger a click on table column header causes an objc- exception.

Re: Sorting on a table view of a managed object - debugger throws exception
Quincy; Hey thanks for some useful data! BUT it is not what is happening in this case. I have a base class MyManagedObject that all entities are derived from. MyManagedObject has the - setNilValueForKey: method defined. I set a breakpoint there and a log message as well. Neither are ever called. I have an array controller whose sort descriptors are bound in IB. This appears to work because the initial display of the table is ordered accordingly. There is no sort key nor selector specified in IB for the table column. The table column value is bound in IB to the array controller. Below is the full trace when I click on the table column header... Thanks for your time!

Re: Sorting on a table view of a managed object - debugger throws exception
Quincey;
Do you in fact have a "code" property? On the app delegate? What's
does it's @property (or accessor prototype) look like?
The 'code' property is declared on an entity: MyEntity.
The accessors were created by XCode itself using the 'Copy Method
Declaration/Implementation to Clipboard'
- (NSString *)code {
NSString * tmpValue;
[self willAccessValueForKey: @"code"];
tmpValue = [self primitiveValueForKey: @"code"];
[self didAccessValueForKey: @"code"];
return tmpValue;
}
- (void)setCode:(NSString *)value {
[self willChangeValueForKey: @"code"];
[self setPrimitiveValue: value forKey: @"code"];
[self didChangeValueForKey: @"code"];
}
The accessors work because the table is sorted when first presented.
Sorted according to the sortDescriptor which is declared in
MyAppDelegate and bound using IB to MyArrayController.
SortDescriptor is, of course, an NSArray - which is also named 'code'.
Furthermore this all works peachy in a Release build on either Tiger
or Leopard.
Clicking on tableColumn headers sort just as expected.
But not in Debug build - In Debug if I click on table column header I
get thrown into an error:
Error setting value for key path value of object 0x852600> (from bound object 0x3cbe30>[entity:MyEntity, number of selected objects: 1](null)): [<
MyAppDelegate 0x852600> setValue:forUndefinedKey:]:

Sorting an editable tableView of managed object
Folks;
I have a simple one column tableView of a managed object.
The text field in the table view is editable.
I want to keep the table sorted when the user manually changes a value,
I have registered for the notification:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(myRefreshManagedObjects:)
name:NSManagedObjectContextObjectsDidChangeNotification object:[self
managedObjectContext]];
This notification is called at appropriate times.
I iterate over the updated set NSUpdatedObjectsKey checking for the
entity.
If I find a match I determine what tableView is to be updated and call
a method which does the following;
- (void) sortManagedTable:(NSTableView *)tableView; {
//array controllers use 'prepare content' and a fetch predicate
//there is NO binding to a sortDesctiptor - the tableView handles the
header clicks correctly without one
NSSortDescriptor *titleDescriptor = [[tableView
tableColumnWithIdentifier:@"titleValue"] sortDescriptorPrototype];
NSMutableArray *newSortDescriptors = [NSMutableArray arrayWithArray:
[tableView sortDescriptors]];
[newSortDescriptors removeObject:titleDescriptor];
[newSortDescriptors insertObject:titleDescriptor atIndex:0];
[tableView setSortDescriptors:newSortDescriptors];
[tableView scrollRowToVisible:[[tableView selectedRowIndexes]
firstIndex]];
[tableView setNeedsDisplay];
}
But the tableView does not update to reflect the new ordering.
What am I missing?

Re: Sorting an editable tableView of managed object
Matt; Thanks that did the trick! I didn't add the binding because I only want to add bindings when I understand the value of doing so. In this case the table column headers all performed their various sorts as expected without the bindings - hence no bound sortDescriptors. Adding the binding does get the UI job done but leaves me at a dead end in my understanding of why the code I submitted doesn't accomplish my goal! Thanks for your time and help!

AppleScript Record and NSDictionary
Folks;
From my Cooca app I want to call an AppleScript with several
parameters one of which is an AppleScript record.
I've got everything about calling and return values working smoothly.
What I can't seem to get is how to create that parameter record.
I have been able to build AppleScript lists using:
NSAppleEventDescriptor *stringDesc, *thisList =
[NSAppleEventDescriptor listDescriptor];
NSIndexSet *rowIndexes = [myTableView selectedIndexes];
unsigned int descIndex = 0, index;
index = [rowIndexes firstIndex];
do {
descIndex ++;
stringDesc = [NSAppleEventDescriptor descriptorWithString:[[myArray
objectAtIndex:index] valueForKey:@"someKey"]];
[thisList insertDescriptor:stringDesc atIndex:descIndex];
} while ((index = [rowIndexes indexGreaterThanIndex:index]) !=
NSNotFound);
When I look at the docs for -recordDescriptor and I see the 4
character code business - I get the ugly sinking feeling but maybe
that's the only way...
I've tried to move the coercion into AppleScript but there is nothing
that will do that except the magic 'user record fields'.
But there are warnings about resouce use for the 'magic' values
(And anyway while seated in front of this machine, I don;t really like
magic!!)
- (NSAppleEventDescriptor) coerceDictionary(NSDictioanary *)dictionary {
NSAppleEventDescriptor *result = [NSAppleEventDescriptor
recordDescriptor];
NSArray *keysArray = [dictionary allKeys];
NSArray *valuesArray = [dictionary allValues];
unsigned int keyCoount = [keysArray count];
for ( i = 0; i < keyCount; i++) {
//the good stuff happens here
}
return result;
}
So is there an exprienced soul out there who might share a snippet of
code or a an illuminating link?

IB TextField Bindings and dragging text
Folks; I have several text fields bound to a mutable dictionary in the window controller. Works fine. I want to provide drag-n-drop text snippets into these text fields. I have all the drag-n-drop working just fine -- (uses custom text fields and the window field editor) Within the performDragOperation there is a [self setString:newString]; This, unsurprisingly, does NOT update the bindings mechanism. Is there a way that I can 'flash' the bindings mechanism from within the custom text field or do I need to build out something in the delegate? Any other notions appreciated!

Intermittent Console Log Entries '.sdef error' - Where from? What does it mean?
Folks;
I have a logging facility built into my application to assist in
troubleshooting from the field.
These 4 lines appear SOMETIMES in user submitted log files:
2009-08-12 10:57:55.383 MyApp[296:20b] .sdef error: (null)
2009-08-12 10:57:55.383 MyApp[296:20b] line number: 2
2009-08-12 10:57:55.430 MyApp[296:20b] .sdef error: (null)
2009-08-12 10:57:55.431 MyApp[296:20b] line number: 2
They occur during a method which processes an array response from an
NSAppleScript:
NSDictionary *errorDict = nil;
NSAppleScript *appleScriptObject = [[[NSAppleScript alloc]
initWithSource:theScript] autorelease];
NSAppleEventDescriptor *eventDescriptor = [appleScriptObject
executeAndReturnError: &errorDict];
if (([eventDescriptor descriptorType]) && (errorDict==nil)) {
return [appleScriptManager
arrayFromAppleEventDescriptor:eventDescriptor];
} else {
...
}
I have never seen these lines appear during any testing on the test
machines here nor during development.
This method is executed by every customer who is submitting a log BUT
these 4 lines only appear sometimes.
There are no apparent repercussions to their appearance.
The log files are fine either way.
What causes this?

Core Data Predicate Builder - comparing dates
Folks; I have a Core Data entity that has a dateCreated and a dateModified - both NSDates in the object files. I'd like to construct a predicate that will retrieve all records where a record's dateModified is greater than that record's dateCreated. Its deceptively easy to setup something that looks like it should work using 'Control-click' and 'Key' in the predicate builder in XCode. But when I run queries it doesn't appear to yield the right results. My thinking is that the comparison operators don't properly evaluate dates (am I wrong?) So dropping back to code - how would I write this predicate in code? Thanks for any help!

Re: Core Data Predicate Builder - comparing dates
Ben; Thanks for taking the time to respond. I believe that I was blinded by a build issue in my allegation that the Predicate Builder mechanism was not giving correct results. This seems to be working fine now. I'm glad you have expressed the fragility issue on equivalence - I'll remember that. Thanks for the predicate in code. It's amazing how often the Cocoa answers are simple and straightforward when you finally see them. I might suggest the predicate you cited be considered for inclusion in the Apple documentation somewhere. Most (all?) the examples use operators and some fixed value. I know it may seem obvious (it does seem obvious now) but, when you don't know, a range of different examples can be a godsend... Thank-you!

Is checking -count worth it?
Folks; I'm really trying to learn how to write smart fast code. Code that takes maximum advantage of all of the battle-tested intelligence built into Cocoa/ObjC2. Now days with the "halo" and the "JesusPhone", I personally smell an excellent book opportunity... But enough chit-chat. I have a mutable array, M. I want to remove an object, O, from M; O might not be in M. M which is being constantly diminished could become empty. Is this code worth it? if ([M count]>0) [M removeObject:O]; OR should I just do [M remove O]; I assume that I can't write better code than the removeObject's use of -indexOfObject to determine the existence/location of O. So there I get 'best performance' for free by just getting out of the way and letting Cocoa do its thing. Is the only way to really tell to test? Or is there a deeper insight that makes the choice clear? Steve ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Coding around a known bug
Folks: I'm looking for some advice on how to code around a Leopard bug (radar 5905139 & 5599887). Leopard broke the following: OSStatus returnCode = TransformProcessType(&psn, kProcessTransformToForegroundApplication); TransformProcessType used to bring a background app to the foreground, which it still does EXCEPT for the fact that the menubar does not get correctly established until the user first brings another app to the foreground and then re-establishes the 'wounded' app as the foreground. Once this 'app toggling' is done, all is well. So I can trap Tiger v. Leopard and do toggling only on Leopard, that's pretty straight-forward. What I'm looking for is best advice on how to get the menubar to be 'right' in code. I've tried: [[NSWorkspace sharedWorkspace] launchApplication:@"Finder"]; followed by an Applescript to 'activate' myself. OK it works, but it jarring to have the 'Finder' just suddenly jump into view and I'm quite sure customers will NOT like it. Any thoughts? Also any thoughts on how possibly to code this so that when, or if, Apple ever fixes TransformProcessType that the fix might right itself and not require a new version.

I have created a folder in my "Applications Support" directory called "Scripts" and copied my script and several items into this directory. Note that this has a space in the full pathname! SO I have tried the following: NSString *myScriptPath = [[self scriptsFolderPath] stringByAppendingPathComponent:@"myUseful.script"]; //yes I have verified this is a valid path!!! NSTask *task = [[[NSTask alloc] init] autorelease]; [task setLaunchPath: myScriptPath]; [task setArguments:[NSArray arrayWithObject:...]]; [task setStandardInput:[NSPipe pipe]]; [task launch]; ERRROR: launch path not accessible So, thinking that the 'space' maybe wanking out the 'setLaunchPath' I tried to convert to a 'safe' url path: NSURL *myScriptFileURL = [NSURL fileURLWithPath:t]; ... [task setLaunchPath:[myScriptFileURL absoluteString]]; Same error! The docs don't make it clear TO ME why I would need special permissions to launch a script in my own "App Support" directory. Am I out in the weeds chasing the wrong rabbits? Any guidance appreciated!

Re: Launch Path Not Accessible
Andrew:
Thanks for the slap on the head!
So I chmod'ed the file and no longer get the 'not accessible error'
YEAH!
BUT now I get:
*** NSTask: Task create for path '/Users/steve/Library/Application
Support/XYZ/Scripts/myUseful.o' failed: 88, "Malformed Mach-o file"
So I must be missing something about the contents of script files.
Here's my script:
myUseful.m
#import
int main(int argc, char **argv)
{
char dummy;
read(STDIN_FILENO, &dummy, 1);
[NSAutoreleasePool new];
NSURL *url = [NSURL fileURLWithPath:[NSString
stringWithUTF8String:argv[1]]];
LSOpenCFURLRef((CFURLRef)url, NULL);
return 0;
}
You will just have to trust me that I DO need to launch the file in
this manner.
What do I need to do to this file to make it into the correct format?
THANKS AGAIN for the chmod help!

Are you sure myUseful.script is directly executable? Just because

if this is an AppleScript, though, you may have better luck working

Nope. NSTask takes a filesystem path, not a URL.

Re: Coding around a known bug - SOLVED (acceptably)
Andrew & Aaron
Yes I have read the discussion in the docs related to
TransformProcessType(). My bad - here's a more complete snippet:
if (...some condition..) {
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) { SetFrontProcess(&psn); }
}
The result of this is that an icon does appear in the dock BUT the
menubar is NOT shown until the application toggling business I
described in the initial email occurs.
I've also tried all Aaron's various suggestions related to NSMenu, and
NSApplication all with the same result.
Seems to me TransformProcessType(&psn,
kProcessTransformToForegroundApplication) leaves the transformed
process in a strange state; a state not expected by NSApplication.
So here's what I've finally gotten to as an acceptable solution.
This flashes the menubar but otherwise the context switch is as
expected - no unexpected app jumps to front.
(AppleScriptTool is a custom object which has various convenience
methods I've developed)
NSString *currentApp = [AppleScriptTool stringFromAppleScript:@"tell
application \"System Events\" to name of first process whose frontmost
is true"];
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) {
[[NSWorkspace sharedWorkspace] launchApplication:currentApp]; //
this step is necessary - if left out the menubar is not updated
[AppleScriptTool
bringApplicationToFront:myAppName]; //uses @"tell
application \"[EMAIL PROTECTED]" to activate" [NOTE: SetFrontProcess() doesn't work]
}
I cannot use NSWorkspace's -activeApplication in the first line
because it sees the calling app as the active app...
It also seems to me that when (if) Apple does fix
TransformProcessType(), since the call to SetFrontProcess() is spelled
out as necessary, that my solution will not break nor result in
undesired behavior.
Maybe someone else will find this useful...
Thanks to all,
Steve

Folks:
I'm looking for some advice on how to code around a Leopard bug
(radar 5905139 & 5599887).
Leopard broke the following:
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
TransformProcessType used to bring a background app to the
foreground, which it still does EXCEPT for the fact that the
menubar does not get correctly established until the user first
brings another app to the foreground and then re-establishes the
'wounded' app as the foreground. Once this 'app toggling' is done,
all is well.
So I can trap Tiger v. Leopard and do toggling only on Leopard,
that's pretty straight-forward.
What I'm looking for is best advice on how to get the menubar to be
'right' in code.
I've tried:
[[NSWorkspace sharedWorkspace] launchApplication:@"Finder"];
followed by an Applescript to 'activate' myself.
OK it works, but it jarring to have the 'Finder' just suddenly jump
into view and I'm quite sure customers will NOT like it.
Any thoughts?
Also any thoughts on how possibly to code this so that when, or if,
Apple ever fixes TransformProcessType that the fix might right
itself and not require a new version.
Thanks,
Steve
Hi, Steve,
The docs appear to mention something that may be of use -- see the
Discussion for TransformProcessType():
You can use this call to transform a background-only application
into a foreground application. A foreground application appears in
the Dock (and in the Force Quit dialog) and contains a menu bar.
This function does not cause the application to be brought to the
front; you must call SetFrontProcess to do so.
Apologies if you are already, but -- are you calling
SetFrontProcess()?
Cheers,
Andrew

Restarting an app -- AppleScript 'launch' in a detached shell
Folks; I am trying to simply restart my app. To my dismay, I cannot find a way to do this in Cocoa. Please enlighten me if I have failed to understand something!! After perusing the archives, what makes the most sense to me is to launch a detached shell that executes a simple AppleScript. The script has a delay of 2 seconds and then simply does a 'launch'.

[task setStandardError:[NSFileHandle fileHandleForWritingAtPath:errorOutPath]]; [task waitUntilExit]; // <-- I've also tried [task launch] but the same result. [[NSApplication sharedApplication] terminate:self]; This unsurprisingly DOES quit the application but the script doesn't appear to execute, nothing further happens... Am I not using the argument list correctly? I also do not see anything at all in the file @ errorOutPath nor do I don't see any console messages. How could I pick up any data on what IS happening?

Re: Restarting an app -- AppleScript 'launch' in a detached shell
Andrew;
OK for the sake of the group I will parade my ignorance so that
perhaps others can learn too...
First I do understand your point that using AppleScript is using an
unnecessary high-level tool when a lower-level tool will do!
Thanks for keeping me on-point there!! Good old-school unix thinking
- always a good thing.
I have 4 questions
1) Given that it is higher-level than necessary, I would still
appreciate understanding why it doesn't work.
I revamped the '&' and added it to the end of the osaxscript command
instead of passing as argument -> no change..
2) In the script you cited, I don't understand the 'if(fork() ||
fork())' conditional test. Can you clarify this statement?
3) Why are you using 'execl' and not 'exec'?
4) When you say "...launch this with a single argument..." I' not
sure of exactly what you mean. Launch how?
I tried creating a text file with your script as the contents
(Restart.unixscript)
//enclose the paths in single quotes because there are potentially
spaces in either path (eg 'Application Support')
NSString *scriptPath = [NSString stringWithFormat:@"'%@'",[[self
scriptsFolderPath]
stringByAppendingPathComponent:@"Restart.unixscript"]];
NSString *myPath = [NSString stringWithFormat:@"'%@'",[[NSBundle
mainBundle] bundlePath]];
NSFileHandle *stdErrors = [NSFileHandle
fileHandleForWritingAtPath:@"/Users/steve/Desktop/RestartErrors.txt"];
NSTask *task = [[NSTask alloc] init];
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:scriptPath, myPath,
nil]]; // no -c means that first parameter is file of commands
[task setStandardError:stdErrors];
[task setStandardOutput:stdErrors];
[task launch];
[[NSApplication sharedApplication] terminate:self];
When I do this I get the following in stdErrors:
/bin/sh: '/Users/steve/Library/Application Support/XYZ/Scripts/
Restart.unixscript': No such file or directory
NOTE: enlosing in double quote doesn't change the result; nor
obviously does not enclosing the paths in a delimiter at all
Seems like I'm missing something
Thank-you for your patience on this!

You're overcomplicating things.
int main(int argc, char **argv) {
if(fork() || fork()) exit(0);
sleep(2);
execl(argv[1], argv[1], NULL);
exit(1);
}
Launch this with a single argument - the path to your application's
executable. It'll background itself, sleep two seconds, and exec
your application.
(Standard disclaimer: typed out in Mail, untested.)
I've got the script working like a champ in a straight terminal
session:
> /usr/bin/osascript '/Users/steve/Desktop/Restart.script'
So now:
NSString *cmdString = [NSString stringWithFormat:@"/usr/bin/
osascript '%@'",[[self scriptsFolderPath
stringByAppendingPathComponent:@"Restart.script"]];
NSTask *task = [[[NSTask alloc] init] autorelease];
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:@"-c", cmdString, @"
&", nil]]; //the '&' detaches the shell, yes?
& only detaches a command when it's part of a shell command. You're
passing it as an argument to /bin/sh here, which is subtly different.

CoreFoundation Command Line Tool - an easy beginner question
Folks;
Here's the pretty simple tool I'm trying to create (THANK-YOU Michael
Ash!!)
int main (int argc, const char * argv[]) {
char dummy;
read(STDIN_FILENO, &dummy, 1);
[NSAutoreleasePool new];
NSURL *url = [NSURL fileURLWithPath:[NSString
stringWithUTF8String:argv[1]]];
LSOpenCFURLRef((CFURLRef)url, NULL);
return 0;
}
I'm using XCode3.1 with the 10.5 SDK deploying to 10.4.
I open new project using the CoreFoundation - Command Line Tool
template, and place the code shown above.
My question is what are the #imports necessary to make this work?
I have figured out:
#import
//for the STDIN_FILENO and the read()
#import //for the
LSOpenCFURLRef
I've tried various usages of #import but
can't seem to get it right so that NSURL & NSAutoreleasePool are
defined...
I believe that both NSURL and NSAutoreleasePool are defined in the
Foundation framework, which is why I am focused on getting it
#imported, I just need the syntax..
(with Foundation framework added to the project)
NO --> #include (~700 errors...)
NO --> #include (45 errors..)
Oh out of exasperation, I tried ---> ~1700 errors
I know this is probably pretty easy for most, but its got me just
bamboozled
THANK-YOU for any help!

StatusItem to foreground app
Folks;
I'm building a tool that I want to allow the user switch 'modes'
either running as a menubar statusItem or as regular dock-based
application.
NOTE: The info.plist has LSUIElement=1.
If the user designates the application to run as regular dock-based
application then, early in startup, I do:
ProcessSerialNumber psn = { 0, kCurrentProcess };
OSStatus returnCode = TransformProcessType(&psn,
kProcessTransformToForegroundApplication);
if( returnCode == 0) {
...
I have this working fine under Leopard, however, the application's
deployment target is 10.4.
On the Tiger machines I'm getting a returnCode = -50.
GetMacOSStatusErrorString tells me that there is an error in the user
parameters.
I have examined the psn high = 0 and low = 2 which seems right to me...
The 10.4 application does NOT die; rather it continues to load and run
EXCEPT there is no menu bar, no dock icon, and it is not listed in
'Force Quit'. (The TransformProcessType has failed.)
Is the LSUIElement confusing 10.4?
Was this a known bug on 10.4 that was never fixed?
Was there a 10.4 workaround?
So here's my predicament:
I need the LSUIElement set to run as a statusItem (yes?)
LSUIElement cannot be changed by code (yes?)
If I have this set LSUIElement then I can ONLY run as a status item in
10.4.
If I do not set LSUIElement then I can NEVER run as a status item in
either Leopard or Tiger
I really don't want to deploy separate binaries for obvious reasons.
Does anyone have any insight into what is going on here?
Thanks for any thoughts!
Steve

Built Menu not firing the action
Folks;
I'm building a data driven submenu programmatically.
The submenu appears correctly in the UI with the correct titles but
nothing happens when these items are selected.
submenu build code:
menu1 = [[[NSMenu alloc] initWithTitle:@"__"] retain];
[menu1 setAutoenablesItems:NO];
NSEnumerator *titleEnum = [someArray objectEnumerator];
while ((nextTitle = [titleEnum nextObject])!=nil) {
[menu1 addItemWithTitle:nextTitle action:@selector(customAction:)
keyEquivalent:@""];
}
...
[[mainMenu itemAtIndex:3] submenu] itemWithTag:1000] submenu]
itemWithTag:1003] setSubmenu: menu1];
I spit menu1 out to NSLog and it looks fine.
I set a breakpoint at customAction: it NEVER gets called.
(Yes I have spelled it correctly [- (void) customAction:(id)sender;]
This is on the mainMenu in the main XIB file. There is an outlet from
appDelegate for mainMenu, this is set.
The menu itself has the appDelegate set as its' delegate.
The selector method is o method in the appDelegate object.
There are no selector bindings set.
(Note: there are enabled bindings set which are working correctly)
I'm just stumped! I probably could use some sleep...
Also how do you show some useful data from a SEL value in NSLog? ie
print [NSMenuItem action]?
Since nothing happens how do I debug this?
Thank-you for any insights!

Re: Built Menu not firing the action
Peter; Thanks for the tip on NSStringFromSelector()! On the responder chain: I'm not sure I precisely understand your question - where are you expecting me to call this? If I call it at the time the submenu is being constructed I get: appDelegate Since I can't get any response to selecting the item itself, I can't tell you what I would get if I called it when the item is invoked =;-( If you use the NSMenu method -addItemWithTitle:(NSString *) action: (SEL) keyEquivalent:(NSString *) what is the recommended way to set the target for the menuItem added by this method? Why doesn't the method allow you to set the target as well as the selector, in one fell swoop? How can I effect the responder chain, if I am just adding a submenu to menuitem on the menubar? The REAL maddening thing here is that I have another similar data driven submenu that uses the same mechanism and it works fine. I've been over and over the IB settings for the darn things and I can't find any differences! Same point in time the submenu are being constructed and attached; and same exact objects involved in the selector Thanks for any additional data.

Strange Strange Bug
Folks; OK this behavior has me a little spooked... This behavior occurs the first time through the method!

For this string variable the 'Summary' will be empty as opposed to all other 'Summary' which have 'Invalid' The debugger is paused several lines above the declaration of this variable... If I merely switch the positions of the variables I can change which variable has the 'bad' instance id. It is always the 6th declared string variable.

Re: Strange Strange Bug
Kai; OK That seems reasonable but: why do I not see this behavior anywhere else? why have I never seen it before now? why if I restart XCode does the 'bad' instance fall on exactly the same string? Thanks, Steve On Sep 5, 2008, at 4:11 AM, Kai wrote: Steve, looks like the debugger tries to inspect your uninitialized string pointers. And it happens that the stack location assigned to the 6th string pointer still contains the address of a now deallocated object left there when another method exited. So this is a debugger-only problem and completely harmless without debugger (if I am not mistaken, of course). To fix it, assign nil to the string pointers when you declare them: NSString *gAsOf = nil; etc.. Or, better yet, do not declare the variables before using them (that is, not all together at the start of the method). (Note that this style may be only possible with certain C dialects. I use Objective C ++, therefore I’m not sure). Hope this helps. Kai On 5.9.2008, at 09:04, Steve Cronin wrote: Folks; OK this behavior has me a little spooked...

Folks; I'm trying in 10.4+ to implement dragging data from a tableView to the desktop. My problem is probably a dunderhead oversight but I can't see it. I have NOT subclassed an NSTableView. In a windowController I do the following in -awakeFromNib: (myTableView is an Outlet) ... [myTableView registerForDraggedTypes:[NSArray arrayWithObjects:NSFilenamesPboardType, NSFilesPromisePboardType, nil]]; [myTableView setDraggingSourceOperationMask:NSDragOperationNone forLocal:YES]; //local [myTableView setDraggingSourceOperationMask:NSDragOperationCopy forLocal:NO]; // external ... I get a local copy, drag some selected rows initiates a 'carrying' cursor, but as soon as I leave my application it invalidates. This is exactly the opposite of the desired/expected behavior... NOTE: If I change both drag operations in the setDraggingSourceOperation method to NSDragOperationEvery - no difference. myTableView has the windowController set as its delegate. The tableView:writeRowsWithIndexes:toPasteboard is being called (its in the windowController too) What am I overlooking?

Horizontal SplitView Resize Question
Folks; I have a horizontal split bar inside of a resizable view -the parent view grows both horizontally and vertically. The standard behavior for horizontal split views appears to be that the the bottom view is grown or shrunk. (In my testing this is true regardless of the resize attributes of the enclosed bottom view) I have ALL of the resize widgets set ON for this splitView. What I would like is the divider to stay fixed at its current height from the bottom throughout a resize and the top view to grow or shrink. Is there a setting I am overlooking or is the way to accomplish this by overriding -splitViewDidResizeSubviews?

How to debug a nib loading error?
Folks; Tiger 10.4.11 -- XC 2.4.1 I'm baffled by an IB error. Reasonable development has been on-going. Pretty stringent Build Rules and no errors or warnings. I decide to do a clean build, torch the app's prefs file and the CoreData store. I want to focus on the initial installation phase of the app... To my great surprise I cannot now get the app to launch successfully. It ran fine 15 minutes beforehand... Regardless of whether I 'Run' or 'Debug' I get the exact same result: I get all the way through the appDelegate's -awakeFromNib and the pref window opens (as I expect on first launch) but the debugger kicks in with the following: #0 0x90a594c7 in objc_msgSend #1 0xb7b8 in ?? #2 0x932849d8 in loadNib #3 0x932843d9 in +[NSBundle(NSNibLoading) _loadNibFile:nameTable:withZone:ownerBundle:] #4 0x9328403a in +[NSBundle(NSNibLoading) loadNibFile:externalNameTable:withZone:] #5 0x93283f7c in +[NSBundle(NSNibLoading) loadNibNamed:owner:] #6 0x93283cc3 in NSApplicationMain #7 0x00405ffc in main at main.m:18 In the Console I see: Normal log messages that I generate and expect (including the 'end-of-awake-from-nib' stamp) Program received signal: "EXC_BAD_ACCESS". I have the [NSException raise] as a Global breakpoint but it doesn't fire. Using the po command I can tell that MainMenu is the nib involved; the prefs window is in a separate nib...

XCode3 & NSLog & Tiger compatibility
Folks; I've finally begun to use XCode3 and I know I need to learn my way around the new world. I have an existing Tiger project that I will be shipping under Tiger but I need to ensure Leopard compatibility. So I can't convert it to the new world - I just need to be able to run/debug it. So immediately I run into the changes to Run log -> Console. OK - I try and understand what's going on but I can't seem to find anything useful which explains: If you have line of Tiger Code: NSLog(@"Hello World"); Where does this output appear in XCode3? I can see it sometimes in the Console.app but not reliably... (I have setup a database query for my 'Sender'.) I can see it sometimes in the Console log in XCode but not reliably.. I can't change the statements to ASL based statements per above.. How can I best use XCode3 to accomplish this mission? Thanks!

CoreData code working on Tiger - not on Leopard
Folks;
I am now testing a Tiger application on Leopard and learning the new
Leopard way at the same time.
I admit I have a lot of Leoparding to do!
I use Core Data (SQLite) pretty extensively on Tiger - life is good.
I take the project and run it without any changes to the model or the
code and Core Date won't save to disk.
I load a set of data on initial launch and at the end of that process
I have Core Data 'save'.
The data loading all appears to run fine:
recX = [NSEntityDescription insertNewObjectForEntityForName:@"XYZ"
inManagedObjectContext:moc];
[recX setValue:@"123" forKey:@"source"];
...
5 different entities and 1,000s of records..
I've looked over the 'Core Data - Release Notes' but I don't see
anything that seems to indicate a model conversion or persistant
store conversions I have not made any changes (no versioning...)
Here's the 'save' code:
- (void) updateCoreData {
NSManagedObject *moc = [self managedObjectContext];
[moc processPendingChanges];
if ([moc commitEditing]) {
NSError *error;
if ([moc save:&error]) {
if (error!=nil) {
On Leopard in the 'processPendingChanges' invocation I get the
following:
0 0x900ef0f4 in ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___
#1 0x93d680fb in objc_exception_throw
#2 0x9649a2a5 in -[NSManagedObjectContext
(_NSInternalChangeProcessing) _processRecentChanges:]
#3 0x964adbea in -[NSManagedObjectContext processPendingChanges]
#4 0x0002032e in -[AppDelegate updateCoreData] at AppDelegate.m:700
BTW: I also get a similar error if, during the loading, I try to get
a 'count' using a FetchTemplate with a null predicate (works on Tiger)
It appears the fetch also causes a 'processRecentChanges)
What am I missing?
Thanks for your help!
Steve

Re: CoreData code working on Tiger - not on Leopard
Folks;
I have a little more data on this issue:
After I have done any insert, if I subsequently call -
processPendingChanges I get an error in CoreData.
There are no pending messages in the log and no custom catch blocks
(other than what is show below).
The debugger halts on the @try command
The Code:
@try { [moc processPendingChanges]; }
@catch ( NSException *e ) {
NSLog(@"%@: Caught %@: %@", NSStringFromSelector(_cmd), [e name],
[e reason]);
}
The Log:
Program received signal: “EXC_BAD_ACCESS”.
The Stack:
#0 0x93d736ec in objc_msgSend
#1 0x9649aed1 in -[NSManagedObjectContext
(_NSInternalChangeProcessing)
_registerUndoForOperation:withObjects:withExtraArguments:]

The Maddening Part:
All of the code works like a charm on Tiger.
I know I must be missing something pretty basic in the Leopard world
but I sure would appreciate a pointer to what that might be!
Thanks!

How to debug this Tiger release error?
Folks; On Tiger, I have an app that has a popup button which allows a user to make a selection from a supporting array. Once a new selection is made a collection of images are redraw in a view. Has been working reasonably well... Now sometimes, not consistently, when the selection is made the app will crash. Sometimes I see the following in the console log: 2008-03-19 01:36:20.231 XYZ[3035] *[XYZMainWindowController setUserSelectedData] XYZ(3035,0xa000d000) malloc: *** error for object 0x315730: double free XYZ(3035,0xa000d000) malloc: *** set a breakpoint in szone_error to debug I have the following environment variables set: NSZombieEnabled(YES) MallocStackLogging(1) and these Global Breakpoints set: [NSException raise] szone_error [NSObject setNilValueForKey] -[_NSZombie release] malloc_printf The crash doesn't appear to fire any of these breakpoints and leaves only this meager trace in the stack: #0 0x90a594c7 in objc_msgSend #1 0x00315730 in ?? #2 0x90824f84 in __CFDictionaryDeallocate #3 0x9080e0c6 in _CFRelease #4 0x927dc96f in NSPopAutoreleasePool #5 0x9328fab1 in -[NSApplication run] #6 0x932839c0 in NSApplicationMain#7 0x00405ffc in main at main.m:18 If I step thru the code it eventually starts off into the assembly code for handling the interface and bindings and as you all are well aware there is an astonishing amount of such code underlying the Mac OS interface If I pause the app and enable a breakpoint on [NSObject release] I get so many breaks that I just can't make any headway. How DO I -- most efficiently -- figure out what dictionary is the culprit in frame 2 above? Thanks for any help!

__setjmp linking error in Leopard
Folks; I'm trying to build a test case for a DTS support incident regarding an issue I posted earlier concerning CoreData in Leopard. I have an existing app which compiles without inicident on both Tiger & Leopard. To build the DTS test project, in Leopard I added the data model and several supporingt classes from this existing app, as well as the AppDelegate. I stripped out all the unnecessary code. I confirmed that all the build settings are identical. I did not write a single line of new code. I have the enable ObjC exceptions option turned ON. When I compile on Leopard I get: "__setjmp", referenced from: +[XYZBase allActiveInContext:] in XYZBase.o +[XYZXBase allActiveInContext:] in XYZBase.o +[XYZManagedObject allInContext:] in XYZManagedObject.o +[XYZManagedObject allInContext:] in XYZManagedObject.o -[AppDelegate(PrivateUtilities) setupDefaultSQLLiteStore] in AppDelegate.o -[AppDelegate(PrivateUtilities) setupDefaultSQLLiteStore] in AppDelegate.o +[Owner loadOwnerInContext:] in Owner.o +[Owner loadOwnerInContext:] in Owner.o +[DataImporter importSupportDataInContext:] in DataImporter.o +[DataImporter importSupportDataInContext:] in DataImporter.o ld: symbol(s) not found collect2: ld returned 1 exit status Build failed (1 error) All of the cited classes contain @try - @catch blocks. Is there another compiler setting I an not aware of? When I compile on Tiger: life is good! No warnings, no errors, runs flawlessly... Identical compiler settings! Man I had no idea how much grief I was going to run into just to get running on Leopard!!! I haven't even execised the bulk of the code I'm just trying to get out of -init!

Consistent Contextual Menu in NSTableview
Folks;
I'm having some difficulty getting consistent contextual menu behavior
in NSTableView.
In the Finder and iTunes (what I feel most users are familiar with) if
a row is selected but the user causes a contextual menu on a different
row then row selection changes.
(I don't want to start a UI flame about 'correctness') I'm only
interested in consistency!!
NOTE: the contextual menu can appear by a right mouse click, a two-
fingered tap, and a control-click which appear to be detected as
different events (see below)
The base NSTableView class does NOT change the selection when a
contextual click occurs on a row
If I sub-class and add:
- (void)rightMouseDown:(NSEvent *)theEvent {
[self selectRow:[self rowAtPoint:[self convertPoint:[theEvent
locationInWindow] fromView:nil]] byExtendingSelection:NO];
[super rightMouseDown:theEvent];
}
I get half-way home. Now the right mouse click and the two-fingered
tap will alter the selection.
BUT
the control-click does not.
The Cocoa adage, "if you are working too hard, you probably are" keeps
rummaging around my brain
What is the preferred means to efficiently make consistent contextual
menu behavior like Finder and iTunes?
Thanks,
Steve

AppleScript - occasional crashes on Leopard
Folks; I've seen some inconsistent behavior on AppleScript running under Leopard. Here's an example: ... NSString *theScript =@"some valid dynamic script text" NSDictionary *errorDict = [NSDictionary dictionary]; NSAppleScript *appleScriptObject = [[NSAppleScript alloc] initWithSource:theScript]; NSAppleEventDescriptor *eventDescriptor = [appleScriptObject executeAndReturnError: &errorDict]; ... will OCCASIONALLY crash at the NSAppleEventDescriptor specification: #0 0x932c3d5c in getDescDataType #1 0x932c7ab7 in aeCoerceDescInternal #2 0x932cc055 in AECoerceDesc #3 0x1d4a8150 in ComponentCoerceDesc #4 0x1d48cbec in ASCompile #5 0x903bacb8 in CallComponentFunction #6 0x1d487ae2 in AppleScriptComponent #7 0x1d4a3927 in AGenericManager::HandleOSACall #8 0x903755cd in CallComponentDispatch #9 0x953fc513 in OSACompile #10 0x93e6edaf in -[NSAppleScript compileAndReturnError:] #11 0x93e6f096 in -[NSAppleScript(NSPrivate) _executeWithMode:andReturnError:] #12 0x93e6ee51 in -[NSAppleScript executeAndReturnError:] Is there a new/better means in Leopard of accomplishing the execution of dynamic scripts? NO the crash is NOT related to the validity of the script, of this I am absolutely certain! (It only crashes sometimes using the same resulting script!!) Is a dual processor Intel creating a risk here? Is there something better I can do to handle the error? Why should I have to use a @try block here? I thought that was what the executeAndReturnError parameter was for!! But I don't get a chance to examine the errorDict. It will crash only every so often My hunch is that crashes are more likely when machine is under load and memory swapping might be involved. This is running on a 4G MacBook... Any wisdom appreciated!

Re: AppleScript - occasional crashes on Leopard
NO threading involved here. Just straight up Cocoa code... Do you know enough about AS internals to read the stack trace and KNOW that the error is during compilation? If so, why is the error not being propagated back thru errorDict? And the biggest mystery (to me anyway) why only sometimes?

Re: AppleScript - occasional crashes on Leopard
Mark; 10 months after the first Leopard seed to developers, 6 months after commercial release, and after 2 system updates to the commercial product, the message to developers using ANY AppleScript in Cocoa is: "No Garbage Collection for you!" Perhaps you can try and understand how this might be potentially irritating to some Turning off Garbage collection has profound impacts on the rest of the code base NOT just AppleScript. As I am sure you are aware, turning off Garbage Collection is WAY more than a compiler switch! For my ongoing better understanding of Cocoa, could you provide a link to where I SHOULD have researched so that I would not end up in this corner.

A Cocoa means to detect SysPref 'Enable access for assistive devices"
Folks; Is there a straight Cocoa means to detect the System Preferences/ Universal Access setting for 'Enable access for assistive devices'? I've found plenty of references on using Applescript to detect this setting. The Cocoa Assistive API seems pretty extensive but I can't glean a way to just determine this setting using Cocoa... I understand the potential 'admin' aspects of the setting. All I want is a means to know what the current setting is. Any links or code snippets appreciated!
