My code is not referencing this. it's all from withing UIApplicationMain(). So I'm not sure how to control this. Any ideas? Thank you. ...
So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets autoreleased from the pool (i.e. the pool is releasing, not when I'm calling [view autorelease], du...

The openGLView and SplitView are resizing asynchronously. i found a solution in apple mail list thread http://developer.apple.com/mac/library/samplecode/GLChildWindowDemo/Introduction/Intro.html and i found a solution with some carbon calls. but now i g...
The idea of MVC itself seems clear to me but I have trouble understanding how the concept 'scales up' to multiple views and controllers. It appears that Cocoa takes the approach of the controller being the 'switchboard' between the model and the view. How would the application be organized and function in case of multiple views? If ther...
I know that table sources need a data source to hold the data that the tableview will display. Lets' say that I'm going to make my AppController be the data source of my tableview and that I make the connection in interface builder. My question is since my actual data is going to be stored in an array,let's call it myArray, when I set th...
Can anyone tell me why this colorUsingColorSpaceName is returning nil? For example, the following code block will print "deviceColor is nill": NSColor *color = [NSColor windowBackgroundColor]; NSColor *deviceColor = [color colorUsingColorSpaceName: NSDeviceRGBColorSpace]; if(deviceColor == nil) NSLog(@"deviceColor is nill"); How can I...
I'm trying to debug an iPhone app I'm working on, and the idea of adding fifty NSLog statements to the various source files gives me the willies. What I'd like to do is write a pair of statements, say NSString *methodName = [self methodName]; NSLog(@"%@", methodName); that I can just paste into each method I need to. Is there a way t...
I'm working on a Cocoa app that monitors what you're listening to in iTunes, and since I'm targeting Mac OS 10.5 and higher, I've decided to use Scripting Bridge. If I try to close iTunes too close to the time that my app polls it for the current track, iTunes will immediately relaunch! The only way to reliably prevent this behavior is ...
Hello, I have a texfield bound to an ArrayController. The controller key is "selection" because I select items from a NSTableView. But when there are no items in the table the textfield shows the gray text "no selection". How can I suppress this text and have just an empty textfield? Or how can I change the "No selection" text to somet...
Hello in my application I have a NSTableView bound to an ArrayController (arrangedObjects). I also have a Details-View (just some textfields) bound to the same Controller (selection).

I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything sim...
