I have been reading up on OS X's Core animation. I would like to know if it is possible to control the OS windows in a similar way to Expose, Time Machine, and or switching user screens. I am aware that it is possible to easily do these effects in your own program. But if one wanted to control Safari's browser windows, let's say, is that...
If a retain (reference) count of an object is greater than 1 in a dealloc method right before releasing does this mean there will be a memory leak? I was debugging my code to find another issue but then ran into this subtle one. One of my object's retain counts was 3 in the dealloc method. This object is a property with retain and is ...

Can anyone just clarify this for me, I was under the impression that to use webViewDidFinishLoad: I would have to conform my class to <UIWebViewDelegate>. However I forgot to do this but found it still works where I was expecting an error/warning. Can anyone explain for me? -(void)webViewDidFinishLoad:(UIWebView *)webView { // do st...
I am very much new to the iPhone SDK. I just haven't been able to find the right search query to find out how to do this kind of checking for the existence of a new or deprecated feature. Case in point: iOS4 deprecates UIKeyboardBoundsUserInfoKey used for checking the height of the keyboard (and moving, scrolling or whatever to adjust ...
This is a design questions, so multiple ideas will be fine. In my iPhone app, I keep track of Multiple players' life, which can increase and decrease over time. After the game is done, I want to be able to show them their life throughout the game, so they can see how they did. Now, this will also be stored in Core Data, so they can lo...

I think) to manipulate their data. Where in...
Is there a way to simulate a break statement in a dispatch_apply() block? E.g., every Cocoa API I've seen dealing with enumerating blocks has a "stop" parameter: [array enumerateObjectsUsingBlock:^(id obj, NSUInteger i, BOOL *stop) { if ([obj isNotVeryNice]) { *stop = YES; // No more enumerating! } else { NSLog(...

I want to use pathForResource, but it doesn't look like it will create the path if one doesn't exist. Therefore I'm trying to create one manually by doing the following: NSString *path = [NSString stringWithFormat:@"%@/%@.plist",[[NSBundle mainBundle] bundlePath],@"myFileName"]; I'm creating files dynamically, so I need to access th...
I'm trying to implement local notifications for a calendar-esque application, and I've hit a barrier with reminder intervals.

Hi, I'm new to Interface Builder and Objective-C. I'd like to layout an iPhone interace in IB similar to the "edit event" or "edit contact" in the native iPhone apps where Grouped Tables are used. It seems like i have to add several very generic-looking Grouped Tables in IB, and then write a bunch of -cellForRowAtIndexPath: and numberOf...
