I have designed an iris shutter animation for a camera view in an iPhone app. Unfortunately, it seems impossible to hide Apple's shutter when the view appears, even if I hide the camera controls and create a custom cameraOverlayView. I have gotten around this by animating my shutter on top of the normal shutter when the view appears, u...

Hi there, Well, the title says it all. I'd like to have a UIViewController which has an Add and a Trash button both right to the title, either by adding two UIBarButtonItems to the navigation item/bar or by adding them to a UISegmentedControl and then adding the SegmentedControl to the item. Is this possible? If yes, how is it achieved ...
From reading the memory management docs in the SDK, I gathered that factory methods (static constructor methods) would typically be retaining the object for me and adding it to the autorelease pool? This would mean I have no need to retain & release an object as long as the pool does not get released before I expect? (Which should be at...

Is transfering a file from the desktop to an iPhone quicker than downloading the same file from the Internet to the iPhone? My app allows users to download video files, which are stored locally on the app. These aren't streamed but instead watched from the iPhone's hard drive once downloaded. The downloads are fairly slow using 3G or ...
I see how to solve the problem but it bothers me that I don't understand why this doesn't work. I have a UIViewController subclass that uses Core Data, so it needs the NSManagedObjectContext. The controller is loaded from a nib file where it's placed under a navigation controller which is inside a tab controller. I tried doing this in i...
If i am palying a sound using the AVAudioPlayer in the AVFoundation framework (I can already do this), is there any way to detect the current level of the audio playing, like a VU meter that is listening to the mp3 playing. I don't want to detect the audio of the mic, just the file playing. I want to animate a mouth to prerecorded audi...
I am having some trouble getting my application to properly resize the text of UILabels when the user does a swipe to delete or other type of delete. Currently, the delete button is covering up the text that is in the cell (if it is really long). I would like for them to operate like how SMS (move clipped text down a line) or iPod (del...
