As I understand it, z-ordering of overlapping sibling views has never

I did the exact same thing in another project and I had no problem

I can't see any difference between the two! But one just wont work...!

The subviews of a view are an array in drawing order. (Element 0 is  
backmost, I believe, but I can never quite remember.) Therefore, you  
can use removeFromSuperview + addSubview:positioned:relativeTo:, or  
sortSubviewsUsingFunction:context:.

Re: NSDistantObject in Core Data

[Sebastian Morsch]

Hi,

I can't answer your first question, but concerning your second one:

check out NSPropertyDescription isTransient:. However, this applies to  
properties, not entities. I don't think entities can be transient in  
the true meaning of the word. But if all properties of an entity are  
transient, it probably has the same effect.


Best,
Sebastian

Please, read the link provided in the previous post. It describe in

Using a runloop without understanding what it does is not a good

Again about NSTableView and NSArrayController bindings

[Michele Barboni]

Hi,
 following Hillegass example (RaiseMan app) I'm trying to populate my  
NSTableView with bindings.


I've a custom class, 3 attributes, call it MyCustomClass.
I've an appController, where there's a NSMutableArray (called table)  
with instances of MyCustomClass.

I've a NSTableView in IB, 3 columns.
And of course an NSArrayController object in IB.

According to Hillegass here's what I've done:

1) (IB) In Array Controller Attributes, Object Controller, Class:  
MyCustomClass and for Key the three names of MyCustomClass attributes.
2) (IB) In Array Controller Bindings, Content Array, Bind to: App  
Controller, model key path: table
3) (IB) For each NSTableColumn of the NSTableView: bindings panel,  
Bind to: Array Controller, controller key: arrangedObjects, model key  
path:  the name of the key column should handle.


Now, in an awakeFromNib:  my application connect and query a MySQL  
database, retrieve entries and store them as MyCustomClass instances,  
then call addObject: on the NSMutableArray table.. but nothing appears  
in my NSTableView..


What am I missing?

One answer is to use a transient attribute to represent the  
relationship. Set the attribute's "kind" to Undefined, and use a  
custom NSManagedObject subclass. Define an instance variable in the  
subclass to hold the actual NSDistantObject pointer, and write custom  
accessors to get and manipulate its value:


	http://developer.apple.com/documentation/Cocoa/Conceptual/CoreData/Articles/cdAccessorMethods.html#/ 
/apple_ref/doc/uid/TP40002154-SW14


If you need a to-many relationship, the instance variable can be a  
NSSet* instead.


Then, add awakeFromInsert/awakeFromFetch methods to the entity's  
custom class to set up the initial relationship (give a suitable  
starting value to the instance variable).


That's the short version -- hope it makes sense.

IKImageBrowserView with NSArrayController bindings

[Florian Soenens]

Hi list,

i have an IKImageBrwoserView bound to an NSArrayController of objects.
The objects all conform to the IKImagebrowserItem protocol.

When running my application, all the images display correctly in the  
browser view, this al works fine, BUT:


In the IKImageBrowserDelegate, i implemented  
imageBrowserSelectionDidChange like this for testing purposes:

(I also have an IBOutlet to my NSArrayController)

- (void) imageBrowserSelectionDidChange:(IKImageBrowserView *) aBrowser
{
NSLog([[arrayController selectedIndex] description]);
}

The problem is that the NSArrayController always logs the same index,  
no mather what item i select in de BrowserView.

I assumed that it would always reflect the currently selected index.

I can fix it by doing this but i am not sure if this is the right way  
to go, or is it just a bug in IKImageBrowserView?


- (void) imageBrowserSelectionDidChange:(IKImageBrowserView *) aBrowser
{
[arrayController setSelectionIndexes:[aBrower selectionIndexes]];
NSLog([[arrayController selectedIndex] description]);
}

Help would be much appreciated.
Thanks,
Florian.

What am I missing?


Adding objects to a NSMutableArray with addObject: is not KVO- 
compliant. This means that observers of the array (e.g. your  
NSArrayController) don't get notified of the change automatically.


There are two easy solutions. One is modify the NSMutableArray  
compliantly. Instead of:


[table addObject: myCustomObject];

use:

	[[appController mutableArrayValueForKey: @"table"] addObject:  
myCustomObject];


The other is to use NSArrayController's addObject: method, which does  
approximately the same thing:


[myArrayController addObject: myCustomObject];

The slight drawback to this approach is that you have to create an  
IBOutlet on your app controller, and hook it up to the array  
controller in IB, so that you can have a reference to the  
NSArrayController to send the addObject: message to.


The other slight complication is that, in general, NSArrayController's  
arrangedObjects is a sorted and filtered version of the content array.  
Adding the object via the NSArrayController may put it in a different  
order from adding it via the NSMutableArray. However, if you have no  
sorting or filtering, the result should be the same.

Re: IKImageBrowserView with NSArrayController bindings

[Florian Soenens]

One more thing on this, if i bind an nstableview to my  
NSArrayController (to just display the path to the image object) the  
arrayController does reflect the changes, like so:


- (void)tableViewSelectionDidChange:(NSNotification *)aNotification
{
NSLog([[arrayController selectionIndexes] description]);
}

The log displays different indexes like it should, so i assume that  
IKImageBrowserView could have a bug in it's bindings.


PS: is it enough to just bind the IKImageBrowserView to Controller Key  
@"arrangedObject" without a Model Key Path?

Not related to your problem, but this style of NSLog has a potential  
pitfall if the description method were to return a string with any of  
the supported formatting sequences in it. It would be expecting other  
parameters to fill in the details.


The usual and simpler version would be:

NSLog(@"%@",  [arrayController selectionIndexes]);

(The %@ get replaced by the result of the supplied object's  
description method)

Animating frame width on UIButton with background image

[Bryan Hansen]

Is it possible to animate the width of a UIButton of  
UIButtonStyleCustom type? I have an animation on frame size which  
works fine when the UIButton is a UIButtonTypeRoundedRect. But has no  
visible affect when I am using a UIButtonStyleCustom with background  
image. I am trying to use a background image that has  
stretchableImageWithLeftCapWidth, but I have also noticed that a  
normal UIImage as the background fails to animate as well. My  
animation code is here:


[UIView beginAnimations:nil context:@"MyAnimation"];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.25];
CGRect tempFrame = myButton.frame;
tempFrame.size.width = tempFrame.size.width + 100.0f;
myButton.frame = tempFrame;
[UIView commitAnimations];

Thanks for the help!
Bryan

reorderable ( outline | collection ) view

[René v Amerongen]

Hi all,

Not yet a complete cocoa question, but I did see last week somewhere  
in an app an one column view.

In this view there where other views vertical drag-able/reorder-able.
When you did drag a view you saw the background getting solid grey and  
the dragging view was getting transparent, then when sliding that view  
over another view this view was sliding up or down.


I cant find it anymore, have googleing for some time now.

Does some one has an idea, which program that could be. So far as I  
remember there was also some code about this.


I want to show this to a client later today. She has less imagination  
how it will work and want to show this.


Thanks in advance

NSArrayController doesn't respond to 'selectedIndex' -- I think you

You should have got a compilation error for this. IAC, the index is an  
integer, not an object, so you couldn't have usefully sent a  
'description' message to it either.

 The drawing order of sibling views in AppKit was never guaranteed to  
be well-defined. In plain English that means the only drawing order  
you can rely on is that subviews will be drawn after their superview.  
I think you can turn on Layer-backed views to make this behaviour more  
predictable, but that's a bit fiddly, too.


 So, no, it's not an IB bug, it's simply a documented inability of  
AppKit. Don't ask me why it isn't supported. Even Carbon does that,  
and it's very easy to do this with good performance. Heck, I  
implemented speedy and correct overlapping with transparency back in  
the System 8 days for MacZoop, and I was just starting out as a  
programmer...

core data + bindings + custom view ?

[eblugamma]

heres a little more detail:
I have an NSControl subclass that maintains a list of cells, and an  
NSMutableArray called "content". I have
successfully bound its "content" to the core data based array  
controller's "arrangedObjects" array. I thought that was all I needed  
to do to get bindings working, so I made my  setContent: accessor  
method so that it kept my cell list updated with the content list...  
this did not work.  my setContent accessor was called once, during the  
initialization phase of the app.


next, I tried registering for KVO on the array controller's  
"arrangedObjects" value, thinking that... since it is an array, it IS  
a "to many" relationship, and I would not only get alerts to changes  
to the array, but also information about the changes, in the change  
dictionary under the "NSKeyValueChangeKindKey" key.  This sort of  
worked. I get a notification when the ArrangedObjects is altered, but  
the information about the change is NOT in evidence. Apparently, this  
is not a "to many" relationship after all?  (ummm... what??!!?!?  is  
this true?) And isn't this KVO a little redundant anyway? doesn't  
bindings do this already? isn't there some way for me to automatically  
get notified BECAUSE "content" is bound to the array controller?  
(which is what I was trying to do with the setContent: method)


currently, I am thinking that I will have to discover the changes  
myself, by comparing my content against my cells. it seems a bit  
redundant (read: wasteful), but that seems to be the order of the  
day... do everything twice.


so in all of this, i am frantically looking for ANY documentation that  
explains how to duplicate any part of something I see and use every  
day... namely the smooth interaction between a custom UI element (that  
works SORT of like a tableview, in that it displays a list of things)  
and an array controller that happens to use core data for its  
content.  The official apple docs, are... anemic at best, and my  
google searches have come up empty.


it seems from my worm's eye view, that what I am trying to accomplish  
SHOULD not be this difficult, nor this kludgey, I really feel like I  
am missing something important, but try as I might, the documentation  
falls extremely short of being helpful.


thanks guys,

Help mangling my server URL

[David]

I'm setting up help for my application to have priority for a server
copy. In Help Indexer I've specified my remote root as
http://foo/help/1.0/ and told it to prefer network files to local
files.

When I run the application and try to look at help it says that
"/help/1.0index.html" could not be found. It should be looking for
/help/1.0/index.html. Why did it mangle the name?

Any ideas appreciated.

XCode 3.1 compiler doesn't like CFDataRef bridge to (NSData *) object.

[Lee, Frederick (Ric)]

Greetings:

The following code:

 

CFDataRef faxMsgData = (NSData *)[[self.faxHistoryItemDict
objectForKey:@"msg"] dataUsingEncoding: NSUTF8StringEncoding];

CGDataProviderRef faxMsgDataRef =
CGDataProviderCreateWithCFData(faxMsgData);

 

 

gives me the following compiler warning:

...: "warning: initialization from incompatible pointer type"

 

 

I get the same warning with/without the (NSData *) cast.

 

What am I doing wrong?

 

Regards,

Ric.

Re: Weird bug in IB...

The drawing order of sibling views in AppKit was never guaranteed to  
be well-defined. In plain English that means the only drawing order  
you can rely on is that subviews will be drawn after their  
superview. I think you can turn on Layer-backed views to make this  
behaviour more predictable, but that's a bit fiddly, too.


So, no, it's not an IB bug, it's simply a documented inability of  
AppKit. Don't ask me why it isn't supported. Even Carbon does that,  
and it's very easy to do this with good performance. Heck, I  
implemented speedy and correct overlapping with transparency back in  
the System 8 days for MacZoop, and I was just starting out as a  
programmer...

Re: Core Data + Unidirectional Relationships

The station has a to-many "ports" relationship with a cascade delete

I delete a station, all of its ports will also be deleted from the

from the ports relationship on the station, but leave the station  
otherwise intact.


This can not be if „port has a to-one "station" relationship with a  
cascade delete rule“. This should be nullify.



My trouble comes in relating the ports and the pipes.  I'd like to  
model the pipe by having a to-one "sourcePort" relationship (to  
represent the port at the start of the tunnel - note: all of my  
tunnels are one-way) and a to-one "targetPort" relationship to  
represent the port at the end of the tunnel.


Sounds right if each pipe is unidirectional.

A port would have a to-many relationship with pipe as the target  
entity.  The difficulty comes in specifying an inverse... for the  
port's "pipes" relationship, I'm forced to choose from either the  
sourcePort or the targetPort as the inverse, and for the pipe's  
sourcePort or targetPort relationships, setting either to port's  
"pipes" breaks the inverse setting of the other.


Ports don’t have only one pipe-relationship. Each port has two:  
sourcePipes and destinationPipes. This has to be as your ports have to  
know if a pipe comes or goes.

NSConnection/NSMachPort and CPU Loads.

Hi Everyone..

I have a Daemon communicating with an application using NSConnection/

extremely heavy CPU loads on the System. Has anyone heard of this, or  
experienced it? I am trying to duplicate what my customer is seeing.  
So far without luck. I just wanted to ping this list, just in case I  
am barking up the wrong tree.

NSTableView Issue

[Chris]

Hello,

This is an issue I've been stuck on for a while, I'm trying to load an  
instance of NSHTTPCookieStorage into a table view.  I have it far  
enough so that when I build the app and load it, it displays this http://i38.tinypic.com/315en3c.png 
.  However when I attempt to scroll up or down, the app does nothing  
and I receive these error message in the console:


*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (2)

and

[ valueForUndefinedKey:]: this class is not key  
value coding-compliant for the key name.


Here are my two table methods for reference:

- (int)numberOfRowsInTableView:(NSTableView *)tableView
{
return ([cookies count]);
}

- (id)tableView:(NSTableView *)tableView
objectValueForTableColumn:(NSTableColumn *)tableColumn
row:(int)row
{

NSHTTPCookie *cookie = [cookies objectAtIndex: row];
NSString *identifier = [tableColumn identifier];
return [cookie valueForKey: identifier];
}


Thank you, any guidance would be appreciated!

An outlet can be an ivar. But his might be private to your superclass.
Always use [self ivar] to access them as someday someone might  
override the method.

In your example you could use
NSWindow *aWindow = [self window]
if you want to do use the window more than one line of code.

Re: JPEG compression in TIFF files. NSTIFFCompressionJPEG

[Heinrich Giesen]

On 13.11.2008, at 00:34, Alexander Shmelev wrote:


Our customer asks us to save images in TIFF files with JPEG
compression. But in NSImage documentation is written that JPEG
compression is no longer supported. Why Apple decided to stop support
JPEG compression in NSImage class?



The difficulties with JPEG-compression in TIFF-files reach back to  
1995. In that year a
draft  from  
the TIFF-people (formerly Aldus, now Adobe)
was published and give a deep look into these difficulties. One of  
the first sentences is:


... TIFF writers are strongly discouraged from using the 6.0 JPEG  
design



In another document 

search for a statement by Tom Lane (the jpeg guru) where he explains :

TIFF 6.0 added JPEG to the list of TIFF compression schemes.  
Unfortunately, the approach taken in the 6.0 specification is a  
very poor design. A new design has been developed by the TIFF  
Advisory Committee. If you are considering implementing JPEG in  
TIFF, I strongly urge you to follow the revised design described in  
TIFF Tech Note #2 rather than that of the 6.0 spec.




Meanwhile some fixes have been made. But we still have TIFF 6.0 and  
maybe the long expected
TIFF 7.0 will never come. The Adobe - TIFF story has never been a  
love story.


To directly use the current TIFF library tiff-3.8.2 may help if  
really needed.

  Hard to say without some basic debugging information. Is "cookies"
being mutated by another thread? Is "cookies" being properly retained?
What do you see if you break on your "NSHTTPCookie *cookie = [cookies
objectAtIndex: row];" line and examine the "cookies" array each time?

Yes, on 10.5 AppKit allows and guarantees the correct behavior of
overlapping sibling views. I'm not sure where to find the Official
Word of this, but it's been mentioned on this list by AppKit engineers
more than once. The old wisdom that this is Not Allowed is no longer
valid if you're targeting 10.5+.

Does HELP cache source location?

[David]

I'm getting really wierd results that make me think the Help system is
caching its source location somewhere. I changed the URL used in Help
Indexer for a network location for help. Sometimes the changes seems
to take effect and often it doesn't. Is it stored in preferences? Does
Help remember across invocations of an application?

I'm originally had http://foo/help. No complaints, but it didn't read anything.
Then switched to using http://foo/help/1.0

I uploaded my content. Now it complains that it can't find,
http://foo/help/1.0index.html. What happened to the directory
delimiter between 1.0 and index.html?

So I added a / at the end of the root URL, http://foo/help/1.0/
No change, same error.

I changed it to http://foo/help1.0/ and I still got an error about
http://foo/help/1.0index.html even though that wasn't the path
anymore.

Now I'm getting weird results where sometimes it complains, and
sometimes it shows the local page.

I need more clarity on what the help system is doing. This black box
magic stuff is ok if it works, but when it doesn't its a HUGE waste of
time.

I believe this guarantee really only applies when using layered back
views. The documentation still currently states the following.

"Note: For performance reasons, Cocoa does not enforce clipping among
sibling views or guarantee correct invalidation and drawing behavior
when sibling views overlap. If you want a view to be drawn in front of
another view, you should make the front view a subview (or descendant)
of the rear view."

I an fairly sure I have seen issues even when compiled against the
10.5 SDK (however it may be a side effect of IB mishandling ordering).
Also IIRC ibtool sill produces warnings about overlapping sub-views
even when you set the xib for 10.5 compatibility.

I believe you should still use nesting (view hierarchy) when you want
to ensure proper ordering.

The documentation is busted. Here's a message from Corbin Dunn stating
that they work without layers:

http://www.cocoabuilder.com/archive/message/cocoa/2008/8/28/217039

And here's another one from Scott Anguish:

http://www.cocoabuilder.com/archive/message/cocoa/2007/11/23/193766

The documentation is wrong, but what else is new?

Not with any of the built-in classes. If mysite.com supports WebDAV  
(e.g. iDisk), then you could use a third-party framework like  
ConnectionKit to get a listing.

Yes, I have found that I should not do it both. That is, if I check also in 
code on maximum/minimum, an error message 'multiple validation errors' will 
come up.

Well, that turns out to be complicated... I have to retrieve the validation 
predicates for max, min from the model:
 
 NSEntityDescription * recipeEntity = [NSEntityDescription entityForName: 
@"Recipe" inManagedObjectContext: [[NSApp delegate] managedObjectContext]];  
NSAttributeDescription * targetDescription = [[recipeEntity propertiesByName] 
valueForKey: @"target"]; NSArray * validationPredicates = [targetDescription 
validationPredicates];
after which the predicates need to be parsed in order to find which is the max 
/ min predicate. Then, the custom error message has to be fed to the managed 
object model's localizationDictionary, which I don't fully understand... The 
following code does not work:
 
 NSManagedObjectModel * model = [[NSApp delegate] managedObjectModel]; 
NSMutableDictionary * localizedDict = [NSMutableDictionary dictionary];
 for (unsigned int i = 0; i < [validationPredicates count]; i++) {  
NSComparisonPredicate * predicate = [validationPredicates objectAtIndex: i];  
NSString * description = [predicate description];  double value = [[[predicate 
rightExpression] constantValue] doubleValue];if ( [description hasPrefix: 
@"SELF >"] )  {   minimumTarget = value;   id validationWarning = 
[[targetDescription validationWarnings] objectAtIndex: i];   [localizedDict 
setValue: @"Test string 123" forKey: [NSString stringWithFormat: 
@"ErrorString/%@", validationWarning]];   [model setLocalizationDictionary: 
localizedDict]; } 
 }
 
Any ideas on how this can be done in a *simpler* way?
 
 
Thanks so far,

Re: core data + bindings + custom view ?

I have an NSControl subclass that maintains a list of cells, and an  
NSMutableArray called "content". I have

needed to do to get bindings working, so I made my  setContent:  
accessor method so that it kept my cell list updated with the  
content list... this did not work.  my setContent accessor was  
called once, during the initialization phase of the app.


I'm not sure what you're saying here, but if you're saying you added a  
"content" property (getter and setter) to your control, then  
programatically used [NSObject bind:toObject:withKeyPath:options:] to  
"bind" the property to an array, then it won't work because that's not  
what bindings are. I won't go into the gory details because this has  
been discussed at length on this list in the last month or so, but the  
short version is that a binding has to be implemented with a lot of  
fiddly code before it can actually be used, and a binding name is NOT  
a property name (though it kinda sorta partially seems to work if you  
mix them up).


It's not usually worth the trouble. It's easier just to use KVO  
notifications directly.


next, I tried registering for KVO on the array controller's  
"arrangedObjects" value, thinking that... since it is an array, it  
IS a "to many" relationship, and I would not only get alerts to  
changes to the array, but also information about the changes, in the  
change dictionary under the "NSKeyValueChangeKindKey" key.  This  
sort of worked. I get a notification when the ArrangedObjects is  
altered, but the information about the change is NOT in evidence.  
Apparently, this is not a "to many" relationship after all?   
(ummm... what??!!?!?  is this true?)


Nope, it's a long-standing bug in NSArrayController. This is also  
often discussed on this list, most recently a couple of days ago.


And isn't this KVO a little redundant anyway? doesn't bindings do  
this already?


The bindings mechanism is built on top of KVO, not the other way around.

isn't there some way for me to automatically get notified BECAUSE  
"content" is bound to the array controller? (which is what I was  
trying to do with the setContent: method)


You *are* getting notified, you said, but just not getting the correct  
change information.


currently, I am thinking that I will have to discover the changes  
myself, by comparing my content against my cells. it seems a bit  
redundant (read: wasteful), but that seems to be the order of the  
day... do everything twice.


That, or observe the underlying array (NSArrayController's  
contentArray) instead of arrangedObjects, or find a way of doing what  
you need without knowing what changed, or ...


so in all of this, i am frantically looking for ANY documentation  
that explains how to duplicate any part of something I see and use  
every day... namely the smooth interaction between a custom UI  
element (that works SORT of like a tableview, in that it displays a  
list of things) and an array controller that happens to use core  
data for its content.  The official apple docs, are... anemic at  
best, and my google searches have come up empty.


Yup, it's very annoying, because you are trying to do the right thing.  
Time for Plan B.

Personally, I go with writing a 'validateTarget' method and do all the  
validations there. The documentation implied you don't need to call  
the built-in property-level validation if you don't need it, but if  
I'm wrong about that then I'd just remove the validation constraints  
from the entity in the model.

EXC_BAD_ACCESS with 10.5.5 AppKit on some MacPros

[Robert Monaghan]

Hi Everyone..

I have a really weird problem with my basic application.
From time to time, on only a very few machines, (running 10.5.5), my  
application crashes when a user clicks on a button. It reports a  
EXC_BAD_ACCESS. Here is the crash report:


Code Type:   X86 (Native)
Parent Process:  launchd [71]

This crash isn't happening with any of my code. It seems to be  
crashing when referring to something in my Object. The weird part is,  
is that I am not releasing anything that the UI would be concerned  
with. The button in question is connected to an IBAction. Nothing fancy.


Ideas??

bob.

Re: Weird bug in IB...

Hi.  This is correct, as prior to 10.5, clipping among overlapping  
views was not enforced, and your program's functionality could very  
well be unpredictable.

If your server allows "directory content listing" (it show you a page  
with the content of the folder when you type the folder adress in a  
browser), you can use webkit to retreive the page, and then extract  
links from the page DOM.

It looks like it is crashing in your code not in AppKit code (the
backtrace may be a little confused if a tail-call optimization is
taking place). It appears that something is attempting to access a
NULL pointer in your code.

Use atos and/or gdb to understand what is going on at/around 0x0031b9a
in your application (you hopefully have a symboled version of what you
shipped to customers).

Review the following for information on how to work with a crash report log...

Creating directory at path, recursively

[Jean-Nicolas Jolivet]

I know there's a method to do just that in Leopard, however I want my  
app to work on Tiger too, therefore I'm trying to put together a  
simple "createDirectoryRecursivelyAtPath" method, however for some  
reason it doesn't seem to work


Here's a simplified version of my method:

- (void)createDirectoryRecursivelyAtPath:(NSString *)path
{
//check if the dir just above exists...
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL isDir;
NSString *directoryAbove = [path stringByDeletingLastPathComponent];
	if ([fileManager fileExistsAtPath:directoryAbove isDirectory:&isDir]  
&& isDir)

{
// Fine, create the dir...
[fileManager createDirectoryAtPath:path attributes:nil];
}
else
{
// call ourself with the directory above...
[self createDirectoryRecursivelyAtPath:directoryAbove];
}
}

Am I missing something? If I'm trying to create for example: /a/b/c  
(and none of them exists) only /a  is created...

Re: NSConnection/NSMachPort and CPU Loads.

[Robert Monaghan]

Here is what my user reports:
- Under extremely heavy CPU Loads, my software app, and the daemon  
looses its connection. The user is rendering a lot of imagery on the  
same machine. I am assuming that the CPUs are being maxed out with a  
lot of threads tying up the machine.


- Just about every user out there with moderate CPU usage appears to  
be fine.

NSString *directoryAbove = [path stringByDeletingLastPathComponent];

{
 // call ourself with the directory above...
[self createDirectoryRecursivelyAtPath:directoryAbove];

Do you happen to listen for NSConnectionDidDieNotification? If so is
that notification coming in? I am curious if things are detecting some
type of connection death or if this failure is silent.

Re: Does HELP cache source location?

[David]

I've removed all references to http://foo/help/1.0 and still it
complains that the url can't be found.

Where is it getting this URL from? I've erased my application's
preferences plist. I've rebooted the whole machine. I've scanned my
project directory for this string even in binary files. I've checked
the helpindex file.

IT IS NOT THERE.

Where is it coming from? Where does Mac help pick this stuff up from?

The "Apple Help Programming Guide" says that help will show up in the
"Library" menu. Library menu of what application? I don't see a
library menu and I don't see it show up.

I'm running Leopard.

Re: Weird bug in IB...

[Jonathan Hess]

There is a bug that causes "custom views", the blue ones, to reverse  
the z-order of their subviews when decoded. You can workaround this by  
re-ordering the subviews in awakeFromNib, or, you can use an instance  
of NSView instead of "custom view".


To create an instance of NSView instead of "custom view", you can  
create a window, select the content view in the outline view, copy it,  
and paste it back into the top level of your document. After copying  
and pasting it to the top level of your document, you might consider  
dragging it back to the library for later reuse.


Good Luck -
Jon Hess

Mounting AFP Programatically.

[Sandro Noel]

Greetings.

I would like to mount the drives off a server programatically without  
having the window open itself when the drive is mounted.
I've tried a shell script, the drive does get mounted but it does not  
sow up on the desktop like it should.

I can see it in the finder tho.

can anyone point me towards the right framework ?

Thank you!

Re: Does HELP cache source location?

[David]

For the benefit of others who may run across this horrible Help design...

I was trying to create help for my application. Used Help Indexer to
give it a remote root url to use overriding local help.

When I first put in the URL, I did it in the form, http://foo/help/1.0

Little did I know that Help does a non-intelligent concatenation of
the URL with the path in the help. This results in the help viewer
looking for http://foo/help/1.0index.html.

Seems very simple right? Just add the / at the end. How hard could that be...

Well turns out that this value gets cached. I've wasted an entire day
because of a lack of transparency regarding what the help system does.

I have to scan the entire file system to figure out where this was
being stored. Turns out it was being cached in
~/Library/Caches/com.apple.helpui/

I erased the application's help cache directory and suddenly it FINALLY worked.

NSColorWell opacity...

I have an NSColorWell which I bound to an NSColor object of my  
controller, however for some reasons, the color well does not display

Didn't you have the API reference in Xcode ?

+[NSColor setIgnoresAlpha:];

http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSColor_Class/Reference/Reference.html#/ 
/apple_ref/occ/clm/NSColor/setIgnoresAlpha:


If the application doesn't support alpha, no opacity slider is  
displayed in the color panel, and colors dragged in or pasted have  
their alpha values set to 1.0. Applications that need to import alpha  
can invoke this method with flag set to NO and explicitly make colors  
opaque in cases where it matters to them. Note that calling this with  
a value of YES overrides any value set with the NSColorPanel method  
setShowsAlpha:.

Somehow I was able to have the opacity displayed by using:

[NSColor setIgnoresAlpha:NO];

In my awakeFromNib...

However, I have no idea why/how it is working... is this setting  
global for the whole app?

Is there a way I can force the NSColorWell to display its opacity

Model mapping crash

[Steven Hamilton]

Hi folks,
I have a Core data application. I've versioned my model, created a new  
version and added one new entity. When I create a mapping model file  
and choose my two models. It creates a default mapping but if some of  
the entities are selected in teh mapping view, XCode hard crashes with  
the following error. If I don't select a broken entity and try and  
compile I get a build failure with the same error. Something about  
unable to parse the mapping string. I've tried upgrading my XCode from  
3.1 to 3.1.1 to no avail. Has anyone seen this before or be able to  
decipher whats going wrong with the string its producing?

True. But it's *supposed* to work I'm not sure exactly what the
practical difference is between not supported but mostly working and
supported but not always working. I guess in the latter case you can
hope that the bugs will be fixed as time goes by.

Re: Does HELP cache source location?

[David]

I take it back. Its not working. Its acting even weirder.

For a file that's missing locally... it works. It obtains it from the
web at the /help/1.0/file.html location.

But for files which ARE present locally, it fails. I get a message such as:

"Multiple Choices
The document you requested (/htlp/1.0file.html) could not be found on
this server. However, we found documents with names similar to the one
you requested.

Available document:
-  /help/1.0 (common basename)"

And the /help/1.0 is a link. If I follow it, I can then access all the
server based files.

I'm at wits end. I cannot figure this beast out.

Can anyone provide any guidance or pointers. Is there some other
mailing list where folks know more about this subsystem?

Again this is on Leopard which apparently has changed the help system.

NSSearchField constants in search predicate binding?

[Steve Mykytyn]

I'd like to use constant values in certain NSSearchField search  
predicate bindings, but can't seem to get them to work.  As in these  
two predicates


ALL

phoneNumber contains $value

USA ONLY

(phoneNumber contains $value) and (countryName contains 'United States')

Is this possible, and what's the correct syntax if it is possible?

 I could not find anything obvious online, and thought the example  
above ought to work

In your situation then yes, you should not do this. Since you want the
smaller view to appear on top of the larger view, you can just make it
a subview of the larger view instead. Alternatively, you can subclass
the larger view and override its drawRect: to draw the label manually.

Note that it is possible to have overlapping views on 10.4. The caveat
quoted else-thread is fairly specific about what doesn't work, and if
you arrange things properly you can work around the problems. I have a
shipping app that's had overlapping views on Tiger for two years with
no problems. But I recommend using just about any alternative you can
find first, especially if you're using standard Apple views. (My
working overlapping views are all custom views.)

The nice thing is that Tiger is a stationary target these days, so if
you get it working on Tiger despite the warnings and rely on the
guaranteed behavior in Leopard, you should be in good shape. In theory
a security update or something of that nature could be released which
breaks your stuff, but that's really unlikely to happen at this point.

Hi Rich,

I've found out that Panther's SNMP dylib's "compatibility version" is
6.0.0 and on Tiger it is 8.0.0, this is different than the actual
source-code version. Leopard comes with the same compatibility version
as Tiger as well as the latest SNMP libraries (they sit side by side).

Since my Bundle was linked with the Tiger SNMP library, even though it
has the same file name on Panther, it wouldn't load the library on
Panther because the compatibility version of Tiger's SNMP library was
greater. So, I linked with Panther's library instead, and did a little
version detection to make some adjustments in my parameters to the
API, and it worked, but the Panther library is PPC only (I had to
remove i386 as a target architecture for it to link at all) and so my
Bundle wouldn't work on Intel.

So, I created a new Xcode project; a fake dylib called
libnetsnmp.5.dylib (the same name as the actual version), and it
contained dummy entries for all the APIs I called from the real
library. I compiled this fake library for both Intel and PPC, and made
the "compatibility version" 6.0.0 so it would load on Panther and
Tiger. When I linked this against my Bundle it would resolve all the
external links OK against this so-called "libnetsnmp.5.dylib", not
knowing that this wasn't the actual library it is going to be using.
My Bundle now also contained information that it requires the SNMP
library with a compatibility version of 6.0.0 or greater.

Keeping my version detection in play, I could now distribute my Bundle
across Panther, Tiger and Leopard and it worked perfectly on both PPC
and Intel, and I don't need to statically link against any libraries,
or distribute a static version of the library either! Huzzah!

It's a Mickey Mouse way to do things but it works. I never like doing
version detection.

Cheers,
Dave.

deep deep copies, or shallow deep copies?

[Graham Cox]

Does anyone know whether methods such as:

[NSArray initWithArray: copyItems:YES];

continue to deep-copy items for further collections within the root  
collection, or do they fall back to a shallow copy (retaining)?


If no-one knows I can spend an hour or two doing some experiments but  
if it's just a known 'yes' or 'no' I'd rather save the time!

It will send the -copy method to each of the items in the array, and
insert the resulting copies into the new array.

So, context specific.  If the items are Cocoa collections, that means
shallow copies of items.

Actually, overlapping subviews are supported in 10.5 regardless of
whether views are layer backed!

The enabling change was to track dirty regions at the window level
instead of at the view level.

Hi Graham,

If you do want a deep copy of a collection, check out . NSPropertyListSerialization would be the Cocoa equivalent of this  
API.

Thanks Ken and Kiel,

I have code that does a deep copy recursively, but I was wondering if  
these methods would be useful in their place. Seems not, oh well.

Re: Detect the login window is being displayed

[Maggie Zhang]

We have login agent and daemon components which do the work regarding user
logout. I am trying the SystemConfiguration which we were using a bit in the
daemon component.

Do you mean I just need to get a callback when somebody logs out?

In order to make SCDynamicStoreCopyConsoleUser work, do I need to find the
current user info and give the uid and gid of the current user? Or
SCDynamicStoreCopyConsoleUser(NULL,
NULL, NULL) will do the work? I tried NULL for uid and gid but I got uid =
56 and gid = 0, which definitely wasn't the right user information I
expected to see.

Will the callback be sent as well when the machine shuts down or restarts? I
only want to get it when user logs out otherwise I won't be able to
distinguish logout from shutdown or restart.

Thanks for your help!

Distributed Objects Performance

[Bridger Maxwell]

Hello,

I am building a server that will rely on distributed objects, and am
worried about the performance. I am not quite done yet, but I  afraid
to spend too much time on this system before discovering it will not
be able to handle the network traffic. Perhaps one of the more
seasoned developers would be kind enough to share his/her thoughts.

Where I work we run space simulations. There are several
"stations/terminals" in each simulator which each have a unique role,
but share much of the same data. To keep everything in sync I would
like to have a central database that contains the entire ship's state.
When a client connects to the server it retrieves the initial state
for all of their relevant keys and subscribes for changes. Any time
that a change is made to one of these items, the new value is pushed
to all of the clients who have subscribed to it. In this way the
clients do not need to poll the server, as they can use the cached
value.

So that is how the networking system will hopefully be set up. To give
a rough estimate of network traffic, there are anywhere between 5 and
30 "stations" in each simulator that will be connected to the server.
Network data would consist mostly of strings, numbers, and arrays. No
particularly large media like pictures, music, or video. I wouldn't
think any of these items would be larger than say a page of apple
docs. However, values would be changed quite often. The server would
be connected through the LAN and would probably be running on a mac
mini.

So, do you think distributed objects is the right solution? Is there a
rule of thumb on network traffic size or maximum number of clients
distributed objects can support?

Thank You,
Bridger Maxwell

You really need to sit down with the numbers.  How big your datasets
are, how sustained your transfer is, how many devices are on each
Ethernet segment, how big the backplanes are in your switches/routers
if your network spans multiple segments... using DO won't introduce
much more overhead than you'll already have to deal with.

This is an absolutely fantastic effort, well done. This is how  
Interface Builder should work out of the box!

You'll need to calculate the amount of data you're expecting to  
transfer, worst case.

I would say about every five seconds often, max. The problem is, once I have
a worst case scenario calculated (which would be very difficult to
calculate, and would be little more than a bad guess), I wouldn't know if
that is reasonable or not. Perhaps there is an example of what DO is well
suited for, and what it is not? Then, as we design these stations we can
either strive for absolute efficiency, or know there is a little breathing
room if it makes the programming easier. I have absolutely no experience
here (in network efficiency) so I feel like I am shooting in the dark.

Thank You,
Bridger Maxwell
