My application seems to have acquired a slightly odd behaviour when it terminates. When I close a the main window using the standard little red button in the top left the application crashes. I haven't made any changes to the application that would obviously cause this problem. I'm struggling to debug the problem because the application ...
Is there any way to tell if a Cocoa application, such as Safari, has finished launching and able to respond? I know it's easy to do using delegates within the actual code but that isn't possible for what I'm doing. Thanks ...
I want to be able to debug C structures without having to explicitly type every property that they consist of. i.e. I want to be able to do something like this: CGPoint cgPoint = CGPointMake(0,0); NSLog(@"%@",cgPoint); Obviously the '%@' won't work, hence the question. ...
I have a simple cocoa user interface with a list of items and a search field, implemented using NSTableView and NSSearchField, respectively. The data source and all of the bindings are set up and working nicely. I see my data in the list, and I can search through it by typing strings in the search field. As I type in more text, the numbe...
I'm using an NSTreecontroller in conjunction with an NSOutlineView in my program, and my program is constantly spitting out: malloc: *** error for object 0x1d70d0: double free. These messages go away when I remove the bindings in IB. Any idea why this is happening? Note: This is behavior is not crashing my program, but I suspect that it...
I'm trying to use the BEncoding ObjC class to decode a .torrent file. NSData *rawdata = [NSData dataWithContentsOfFile:@"/path/to/the.torrent"]; NSData *torrent = [BEncoding objectFromEncodedData:rawdata]; When I NSLog torrent I get the following: { announce = <68747470 3a2f2f74 6f727265 6e742e75 62756e74 752e636f 6d3a3639 36392f...
I wanna have a NSString object as NSData. Later this NSData-Object should return his stringValue with: NSData *data; NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; string shouldn't be nil... =D ...
I really enjoy using RBSplitView, an open source replacement for NSSplitView, but I have a problem in my shipping app and am experiencing it again in a new project. The problem is I'm telling the RBSplitView to autosave its position state by giving it an autosave name. When my app launches the RBSplitView doesn't seem to honor the save...

I have a project that compiles with some warnings. It's an iPhone project that uses some methods on NSDate, that are seemingly not the headers of the iPhone SDK, but work flawlessly none the less. When I call these methods I get warnings like: So how do I silence the warnings permanently, in order to tell XCode "it's OK, really." O...
Hello, I have a problem which I have been struggling with for a while. I have a Cocoa library which acts as a wrapper for a C++ library. C++ library is tested using a set of BOOST unit tests. The tests run normally under both debug and release modes. In order to test the Cocoa wrapper I am using otest. Here is the strange part, the te...
My iPhone client has a lot of involvement with asynchronous requests, a lot of the time consistently modifying static collections of dictionaries or arrays. As a result, it's common for me to see larger data structures which take longer to retrieve from a server with the following errors: *** Terminating app due to uncaught exception 'N...
Mac OS X Leopard has a virtual desktop implementation called Spaces. I want to programatically detect which space the user is currently on. Cocoa is preferable but AppleScript is acceptable if there's no other way. I've seen a couple of AppleScript implementations, but the techniques they used seemed a bit too hacky to use in producti...
I have a block of code which is similar to the following: for (NSDictionary *tmp in aCollection) { if ([[bar valueForKey:@"id"] isEqualToString:[tmp valueForKey:@"id"]]) { break; } else { [aCollection addObject:bar]; } } Is this technically an exception in Objective-C 2.0? It appears you cannot mutat...
Hello all - How can I use two separate CABasicAnimations to simultaneously animate the same property? For example Two CABasicAnimations, both animate position.y. The first animation will be a bounce (from 100, to 300, duration = 1, autoreverse = yes, repeatcount = 10) The second animation will be a slow scroll (by 100, duration = 10)...
I looked high and low for information on how to handle drag n drop to the dock in OSX. The drag n drop documentation (http://developer.apple.com/documentation/Cocoa/Conceptual/DragandDrop/DragandDrop.html#//apple_ref/doc/uid/10000069) I found all deal with dragging from view to view. If anyone can point me to some code samples, that woul...
Curious, how does an NSMutableArray mutate into a type of UIButtonContent? I'm currently working with an instance variable of type NSMutableArray which crashes upon receiving an error with: *** -[UIButtonContent count]: unrecognized selector sent to instance 0x393ed0 Wasn't even aware of UIButtonContent, so not explicitly working with ...
In observeValueForKeyPath:ofObject:change:context: - why do the docs use NULL instead of nil when not specifying a context pointer? ...
I'm used to programming and having log messages be viewable. I know you used to be able to use NSLog() to trace out messages when debugging Cocoa apps. What is the best way to "trace" messages when coding in a iPhone XCode development environment? ...
I'm trying to animate the drawing of a circle. Something the Shazaam app is doing while recording, but much simpler. I've got this code in the drawRect: method to draw the circle: CGContextRef currentContext = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(currentContext, 0.86, 0.86, 0.86, 1.0); CGContextSetLineWidth(currentC...
