I am using KVC to set properties of objects from a plist. I know I can save them as strings <string>{{66, 114}, {64, 64}}</string> and manually convert to structs, but how can I save for example a CGPoint or CGRect in a plist in a way that Cocoa KVC would understand? The Key-Value Coding Programming Guide seems to indicate that I need to...

I made a little test app to try to isolate this issue, but it exhibits the same behavior: the applicationMusicPlayer stops playing immediately when the app enters the background.

I have #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 40000 ...code #endif around my stuff but it seems to be failing on initial launch and I am thinking due to the linking of the EventKit....
So I know iOS apps run in a sandbox and all, but I thought I remembered Apple mentioning a way for apps to write to and read from a common file share, so that you can then deal with these files on your computer when you plug you iPhone in (mount the drive). I think this was in the context on the iPad, but I'm not sure. Anybody know anyt...

Hi everybody, A friend of mine told me that some frameworks (PhoneGap and/or QuickConnect) can transform my HTML/JS/CSS code to an iOS App. Personally, I hate this kind of frameworks because when you get a bug, it's very hard to debug. But, on the other hand, as i'm starting learning iOS programming, I find Objective-C hard to learn. ...
