Re: BSD TCP Programming on iPad

[Bing Li]

Dear Lance,

Your experiences are important to me. I would like to use BSD sockets to
implement the peer-to-peer model.

I got a basic problem. I follow the book, Unix Network Programming, 3rd
edition. When compiling the simple code, TCPEchoServer, some errors exist in
unp.h. Moreover, the basic APIs, such as Socket, Bind and etc, cannot be
linked.

I commented the lines that cause errors in unp.h. Is it proper? But I don't
know which frameworks in Cocoa should be added so that Socket and Bind can
be compiled.

Could you please give me a hand?

Thanks,
Bing

How to store main window frame to user defaults?

[Vyacheslav Karamov]

Hi All!

I need to save main window size and position to user defaults:

 NSValue * rect = [NSValue valueWithRect: [[NSApp mainWindow] frame]];
 [[NSUserDefaults standardUserDefaults] setObject:rect 
forKey:@"MainWndFrame"];


but console output is:

2011-04-28 11:45:00.139 UserDefaults[32801:a0f] *** -[NSUserDefaults 
setObject:forKey:]: Attempt to insert non-property value 'NSRect: {{525, 
701}, {303, 99}}' of class 'NSConcreteValue'.

Re: How to store main window frame to user defaults?

[Aaron Burghardt]

Use NSStringFromRect() and NSRectFromString() to convert to/from a string to 
store in the defaults. However, it might be easier to set frameAutosaveName and 
let the window save and restore the frame itself. Just enter the key in the 
autosave attribute in Interface Builder and it should work.

Show UIActivityIndicatorView asynchronously

[Philip Vallone]

Hi,

I have a UIViewController that can take a few seconds to load. The view 
searches an XML file and eventually displays the resuts.  I want to show a 
UIActivityIndicatorView while the view loads. Unfortunately they are on the 
same thread. How can I get the UIActivityIndicatorView to display befiore the 
view loads? With the below code, the UI freezes up (indicator never shows) 
until the search is done.

[self.activityIndicator startAnimating];   

TitleSearchResultsViewController *controller = 
[[TitleSearchResultsViewController alloc] 
initWithNibName:@"TitleSearchResultsViewController" bundle:nil];
[controller setTitle:@"Search Results"];


Thanks,

Phil

Re: How to store main window frame to user defaults?

[Vyacheslav Karamov]

I can't use Interface builder, because it crashes while opening NIB 
file. I'm currently using XCode 3.2.6, but NIB file was created with IB 
2.x using plug-in.
So, where is it better to save main window frame? I've tried to do do it 
in [NSWindow close]:


- (void) close
{
NSString * rc = NSStringFromRect([[NSApp mainWindow] frame]);
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: rc forKey:@"MainWndFrame"];
[super close];
}

but it doesn't work.

Accessing NSWIndowController attribute from a subview in IB

[Ben Golding]

I feel like I should be able to figure this out but I feel like I'm going 
around circles.  I've looked through the mailing list and can't find anything 
similar (but I might be searching using the wrong terms).

I have a document-based app which loads a couple of NSWindowController 
subclasses.  That's fine.  In one of the subclasses, I load a nib with a NSView 
subclass.  It wants to access one of the instance vars in the window controller 
subclass.  I thought "no worries, I should be able to hook up a connection in 
IB and it will be right".

In my NSWindowController subclass (called "Face"), I have a method:

- (id)initWithSundial:(Sundial *)sundial
{
if ((self = [super initWithWindowNibName:@"Face"]) == nil)
return nil;

[self setSundial:sundial];

return self;
}

In the window that's loaded from Face.xib, there's a custom view (SundialView) 
which needs to access the sundial instance variable in File's Owner.  I just 
don't seem to be able to control-drag in some order to hook them up and I think 
I should be able to.

Am I doing this the wrong way or do I have some sort of misunderstanding about 
how this works?

Ben.

Why not build one if you need it? Does not sound that hard.

Binding a to-many relationship into a table subview of NSCollectionItemView

[Gustavo Pizano]

Hello all.

I have been researching and I only found somebody who had the same problem, but 
the question went unsolved, so Im sorry if I ask again, I hope somebody can 
enlighten me. 

I have a NSCollectionView and its respective NSCollectionViewItem,  also I have 
a NSTableView wich displays the properties of an Entity VERSION,  The 
NSCollecitonView contents its bound to the selectedObjects of this table, so 
one I select something (1 or more) I see that the view I designed for the 
NSCollectionViewItem appears with the properties of VERSION (which were bound 
to the NSCollectionViewItem as representedObject.number , etc).
Now problem is that VERSION has a to-many relation with a entity called 
FILES_PER_VERSION, and in the view of the NSCollectionViewItem need to display 
in a table the properties of this entity.

I have tried using directly IB bindings but that doesnt seem to work. So I 
subclassed NSCollectionViewController and add a NSArrayController as an ivar 
called representedToVersionFilesArrayController.

then in the setRepresentedObject Im doing the following:



-(void)setRepresentedObject:(id)representedObject{
[super setRepresentedObject:representedObject];

if([[representedObject entity].name isEqualToString:DPA_VERSION_KEY] ){
NSLog(@"DP Analyzer >>> represented Object is kind of entity 
DPAVersionFile");
DPAVersion * ver = (DPAVersion *)representedObject;
NSLog(@"DP Analyzer >>>  Got version files ");
self.representedToVersionFilesSet = [[NSArrayController alloc] init];
[self.representedToVersionFilesSet setAutomaticallyPreparesContent:YES];
[self.representedToVersionFilesSet setEntityName:DPA_FILE_VERSION_KEY];
[self.representedToVersionFilesSet 
setManagedObjectContext:[(DP_AnalyzerAppDelegate *)[[NSApplication 
sharedApplication] delegate] managedObjectContext]];
[self.representedToVersionFilesSet bind:@"contentSet" toObject:ver  
withKeyPath:DPA_VERSION_TO_VERSION_FILES_KEY options:nil];

}


}

and then in IB in the table with is inside the view of the 
NSCollectionViewController (or in this case my subclass of it), Im binding each 
table column to 
representedToVersionFilesArrayController.arrangedObjects.http://lists.apple.com/mailman/options/cocoa-dev/archive%40mail-archive.com

I've not used NDAlias for alias files, only for alias records.  I just
looked at the example, and it does seems somewhat crusty.  Still, I
think you are misunderstanding the 'fromFile' parameter.  Have you read
Apple's docs for FSNewAlias()?  That should clarify things.  I'll be
pushing a couple of minor fixes to the example regardless.

The standard conspiracy theory is because aliases come from Classic Mac
OS, and the unix/Cocoa folks hated everything from there, that they were
never added.  Whatever the delay, they are finally in Cocoa as of 10.6.
Mysteriously, they decided to switch from the term 'alias' to 'bookmark'
despite the term alias being consistently used in both the UI and API
since System 7 (and the term 'alias' persists in the UI, and the term
'bookmark' is already overloaded). Rant over. :)

You can not. The display will wait for the end of the runloop.

Your UI would still freeze, even if you could get the indicator on screen.

Your controller needs to to its work in another thread and signal the main 
thread if it is done.

You can not connect to an ivar/attribute of an object. You can just connect to 
an object.

Either or both.

The view itself should not know anything about its controller or the 
controllers ivars. Wrong direction.
You should make your WindowController set SundialView's sundial when it has 
been loaded. Problem solved.

Is the window in the NIB a standard NSWindow or is a subclass? You can't 
override -[MYWindow close] in your subclass and expect it to change the 
behavior of the superclass.

If the window in the NIB is an instance of your subclass, then the explanation 
may be that the runtime is skipping some cleanup and exiting quickly, leaving 
the cleanup to the OS. I think it does this instead of releasing/freeing some 
objects, but I'm not sure what else might be skipped. Regardless, it probably 
makes more sense to move your code to the NSApplication delegate method 
applicationWillTerminate:.

Tab spacing in NSTextView

[Дмитрий Николаев]

Hello!

I'm trying override - boundingBoxForControlGlyphAtIndex for NSTypesetter, but 
logs shows that this method never called.

If this is most appropriate place to override position of the tab

Re: Binding a to-many relationship into a table subview of NSCollectionItemView

[Gustavo Pizano]

Hello again me.

So I solved this doing the following.

Separate the NSColletionViewItem into a different XIB.
In the Main Xib the the Object Controller for the NSColletionViewItem tell it 
to load from that new XIB.
Now the funny part, Bindings and Core Data still doesn't work, so what I did 
was :


-(void)setRepresentedObject:(id)representedObject{
[super setRepresentedObject:representedObject];

if([[representedObject entity].name isEqualToString:DPA_VERSION_KEY] ){
DPAVersion * ver = (DPAVersion *)representedObject;
self.dataSource = [[NSArray arrayWithArray:[[ver 
valueForKey:DPA_VERSION_TO_VERSION_FILES_KEY] allObjects]] retain];
}
 
}


and then I connect the dataSoruces and delegate of the table view to the File 
Owner (which is my subclass of NSCollectionViewItem), and then implemetn the 
proper methods and voila it worked..

Now a downside is that I will have to implement the sort of the table because I 
lost that feature as Im not using an NSArrayController to populate the table 
but a datasource.

No. It will be *far* easier to use -[NSParagraphStyle tabStops] or
-[NSParagraphStyle defaultTabInterval] with tab characters, rather
than control glyphs and a custom typesetter.

Re: How to store main window frame to user defaults?

It doesn't work because NSValue objects aren't valid in a property list, which 
is what the user defaults are.

That's why, if you can't using the window's autosave name for some reason, you 
use NSStringFromRect() instead, as was already suggested.

Another alternative is to use a NSData object, whose data is an archive (via 
NSKeyedArchiver encodeRectForKey:, most easily) of the frame. You use an 
archive so that architecture (word size/endianness) issues are taken care of 
for you automatically.

You could control-drag to connect a controller *outlet* to a view.

You could control-drag to connect a control's *action* to a target.

But you're doing neither here. You don't need to. The code in your custom view 
can simply access the controller property directly as '[[[self window] 
windowController] sundial]'.

There are only a couple of gotchas in this.

First, make sure that the window controller's 'window' outlet is actually 
connected to the window in the NIB.

Second, the view's access to the window's windowController property won't be 
available until some point in the NIB loading process (specifically, not until 
after the view is added to the window's view hierarchy). If you try to 
reference the property too early, you'll get nil. 'viewDidMoveToWindow:' is a 
good place to intervene if you want to know when the window controller is 
available to the view.

Use delayed performance. Here's sample code from one of my own apps:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath 
*)indexPath {
[act startAnimating];
// jump out using delayed performance, to give us a chance to start 
animating the UIActivityIndicatorView
[self performSelector:@selector(showItemsForRow:) withObject:indexPath 
afterDelay:0.1];
}

And then showItemsForRow inits the view controller and loads its view in the 
usual way. m.

Re: Aliases with NDAlias not appearing where I tell them to be.

[Kevin Muldoon]

FSNewAlias() huh? I'll take a look. So, you think I'm reversing the
'fromFile' parameter with 'aliasWithPath' ? That would be embarrassing!
Still, the example code shows the following...


NSString * kDirOfTestProject = @"~/Developer/Projects/NDAlias/"; // you need
to change this to the location of NDAlias


NSString * filePath = @"Test File.txt",

* folderPath = @"Test Folder",

* aliasFilePath = @"AliasFile";


testCreatingAliasFileFor( [[kDirOfTestProject stringByAppendingString:filePath]
stringByExpandingTildeInPath] );



void testCreatingAliasFileFor( NSString * aFilePath )

{

if( [[NDAlias aliasWithPath:aFilePath fromPath:NSHomeDirectory()]
writeToFile:aliasFilePath] )

{

printf("I have created an alias file for\n\t%s.\n", [aFilePath
fileSystemRepresentation]);

[[NSWorkspace sharedWorkspace] selectFile:aliasFilePath
inFileViewerRootedAtPath:@""];

}

else

{

printf("Alias file creation failed.\n");

}

}


or in other words..

The variable aFilePath passed into the function testCreatingAliasFileFor()
is clearly the full path of the file I want an alias of.

The NSHomeDirectory() at fromPath is clearly the path to the users home
directory.

The variable aliasFilePath (which should be renamed to something like
aliasFileName) is the name of the alias file that writeToFile needs,
apparently stringing fromPath of the method it's wrapped around.

Anyway, thanks for the rant! I very much appreciate a historical perspective
on things. I'll keep banging away it when time permits.

Yes, but this isn't what you did, or what you wanted. The sample code is 
intentionally putting the created alias file in the *current* directory, which 
is why 'aliasFilePath' specifies no explicit directory. You want to put it in a 
different place (the desktop), but you passed 'aliasName' instead of 
'aliasFilePath' for that parameter.

Re: iOS Version Install Base

[Steve Christensen]

We're only supporting iOS 4.0 and later since we feel like there's sufficient 
adoption rate to make it worthwhile. Certainly if you feel like you still need 
to support pre-4.0, you could build against the current 4.x SDK, set the 
deployment target to be iOS 3.x (or whatever), and conditionally include the 
non-block animation code with a runtime check to handle each case. Putting a 
build-time conditional around the "legacy" code, and runtime check, means that 
it automatically gets compiled out when your builds stop supporting pre-4.0.

#if __IPHONE_OS_VERSION_MIN_REQUIRED < __IPHONE_4_0
if (![UIView 
respondsToSelector:@selector(animateWithDuration:animations:completion:)])
{
[UIView beginAnimations:...];
...
[UIView commitAnimations];
}

{
[UIView animateWithDuration:...];

I think Quincey is right, which is probably why the beginning of the
example calls and prints the result of getcwd().

This was wrong though, as 'aliasFilePath' was not a full path.  I've

onSocketDidDisconnect in CocoaAsyncSocket

[Bing Li]

Dear all,

I started to use CocoaAsyncSocket to establish TCP connections among iPads.

I got a problem. According to the references (
http://code.google.com/p/cocoaasyncsocket/wiki/Reference_AsyncSocket),
onSocketDidDisconnect would be invoked immediately if the connection is not
already disconnected. I felt confused. What does "not already disconnected"
mean? I think onSocketDidDisconnect should be called when a connection is
disconnected. The description in the reference is wrong?

I implemented a server and a client using CocoaAsyncSocket. When closing the
client disgracefully, I noticed that onSocketDidDisconnect was NOT called.
Anything wrong with it?

Thanks so much!

Why not build one if you need it? Does not sound that hard.

Maybe you can utilize my collection view class:

Here are some questions that might help get some further context:

how are you closing the client "disgracefully"?  

did the companion [AsyncSocketDelegate onSocket: willDisconnectWithError:] 
method get called?  

did you properly set your delegate and define that your object (the one that 
holds your delegate methods) conforms to the delegate protocol in it's .h file?

Scroll view within scroll view blocks scrolling

[Indragie Karunaratne]

Despite the confusing title, I'm sure this is an issue that someone else has 
run into before. I have a parent scroll view that houses a bunch of subviews, 
including an NSTextView (and its own scroll view). The problem is that if I try 
to scroll vertically through the parent view, the text view's scroll view 
"blocks" my scrolling if I try to scroll while the cursor is within the text 
view. How can this be avoided?

Thanks,

Yes, you're right.  I wanted to try to make IB do everything but it can't.  I 
(independently) did exactly as you suggested and it works fine.  Thanks.

By not embedding scroll views inside other scroll views?

Is there a reason you want to do this? Can you not just resize the
contents of the outer scroll view to fit your NSTextView plus whatever
other content you want?

Scroll views within scroll views seem like potentially VERY confusing UI's for 
end users.  I can't think of any major shipping apps that have scrolling 
NSTextViews contained within a parent NSScrollView. Wouldn't it be possible to 
try to simplify the user interface?

But if you insist on going this route, I believe one way of solving your 
problem would be to detect where the event is happening, and if it's happening 
in the sub-scrollview.. have the parent scrollview resign first responder so 
events can flow through to hit the sub-scrollview.  When the mouse exits the 
subscrollview, re-enable (or becomeFirstResponder) the parent scrollview.  I'm 
not certain that this is right solution or not, but at least this might help 
give you some good hints.

Re: Scroll view within scroll view blocks scrolling

[Indragie Karunaratne]

I have resized all my text views so that all the content is visible without 
vertical scrolling, and I have disabled the vertical scroller on its scroll 
view. I would remove it from the scroll view entirely and avoid this issue, but 
I still need the text view's scroll view to horizontally scroll text. Would I 
be able to subclass the text view's scroll view to pass scroll events to the 
parent scroll view?

It sounds like the only scrollview you have now is the scrollview that contains 
the text, yes?  Or do you still have one scrollview (the one that contains the 
text view) inside another?  

p.s. Quincey mentioned Safari.  Bleh. I should've thought of the browsers.  
Safari has to handle all kinds of completely fugly website layouts.

Re: Scroll view within scroll view blocks scrolling

[Indragie Karunaratne]

I have one inside another. The parent scroll view contains a bunch of stuff 
(the text view being just one of the subviews). I would use the text view 
without its own scroll view if it weren't for the fact that I still need 
horizontal text scrolling.

Why not just let the outer scroll view also scroll horizontally?

I can resort to this if there is no other option, but I would prefer not to 
have to do that because extending the text view past the margins I have on the 
parent view wouldn't look that great.

Compile Error Wierdness

[koko]

I have built an iOS Cocoa Touch Static library.  The source is C++.  Builds 
with no error or warnings.

NOw I add this library to a View based iOS project.

I add a C++ file defining a test C++ class.

IN the .cpp I include a header for access to library finctions ... and here is 
what is wied to me ...

I get errors in the files that compiled as the library.

I get the following on inline, class and  statements

error: expected '=', ',', ';', 'asm' or '__attribute__' before '&' token

So is there a setting I am unaware of that lets me use this library in an iOS 
app?

Re: Scroll view within scroll view blocks scrolling

[Indragie Karunaratne]

Figured out a super easy solution for this. Override scrollWheel: in an 
NSScrollView subclass:

- (void)scrollWheel:(NSEvent *)theEvent
{
[super scrollWheel:theEvent];
[[self nextResponder] scrollWheel:theEvent];
}

Works great :-)

Also iTunes -- the Apps tab, for example. I suspect, like Safari, it's using a 
WebView. I wonder if they'd designed the iTunes UI differently if there were no 
WebKit.

Will this give the best behavior?  Without testing, I assume that this
always hands scrolling off to the superview (in your case).

However, when I view a page in, say, Safari that has a scrollable
textarea, I observe that:

1) If I start scrolling with my cursor in the textarea it scrolls the
textarea.

2) If I start scrolling outside the textarea and scroll through it, the
page continues to scroll instead of triggering scroll of the textarea.

3) If I pause scrolling with my cursor in the textarea, there is a
couple second period during which resuming scrolling will still scroll
the page.  After this "cooling off" period, scrolling is handled as in
case #1.

While such behavior might not be what you envision, it does seem to be
uniform across multiple browsers and therefore might be what a user
expects (if you choose to go this route).

Re: Scroll view within scroll view blocks scrolling

[Indragie Karunaratne]

Notice that in my code I'm making a call to super, so using the above code, 
scrolling inside the text view would scroll both the parent scroll view and the 
text view scroll view at the same time. In my case, 2) was the only important 
thing for me because my text views don't scroll vertically (only horizontally). 
You could make it behave like Safari by using an NSTimer to create the "cooling 
off" period, but this simple workaround was good enough for my needs :)

Well, apparently, compiling for iOS app versus iOS static lib treats the 
processing of the .pch diifferently.
Moving some things out of .pch in the app build which are in the .pch of the 
lib build solved my problem.
I would like to know more about this if anyone can shed some light.

a. Don't cross-post. It violates the list guidelines.

b. It's likely not an Xcode problem or a Cocoa problem.

c. It's highly likely that your problem is the rookie mistake of leaving out a 
semicolon (or some similar syntax error) at the end of the .h file included 
just *before* the .h file where the error is reported. In "moving some things 
out", you probably eliminated the problem by luck.

If you put it in the .pch, it will get compiled for each of the languages used 
in your project, including obj-c (which does not understand "class'). The lib 
probably does not have any .m files, whereas the app does.

That's my guess. You can put preprocessor conditionals around the C++ code so 
that it only gets precompiled for the languages that support C++. 

For example:

#ifdef __cplusplus 

// code that requires C++ or obj-c++

#endif
