问题 I've been struggling with adding assets from the iPhone Photo Library to a AVMutableComposition and then export them. Here is what I got: Finding the assets: (here I grab the AVURLAsset) -(void) findAssets { ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init]; // Enumerate just the photos and videos group by using ALAssetsGroupSavedPhotos.

问题 So I am trying to log into my site using an NSMutableURLRequest which presents the credentials via a post. As a noobie, I have some questions about the functionality of this method to make sure I am understanding it.

问题 I was just curious weather it is a good idea to call viewdidload a method like in an ibaction or something of that kind. thanks, TC 回答1: Check: UIViewController Class Reference viewDidLoad This method is called after the view controller has loaded its associated views into memory. This method is called regardless of whether the views were stored in a nib file or created programmatically in the loadView method. This method is most commonly used to perform additional initialization steps on

问题 When I'm running my app on my device using XCode and I have a crash it's easy tracking where it happened on code. However, when I deploy my ad-hoc version to testers and they have a crash, is there a way for me to load the crash on XCode as if it crashed on my computer, actually seeing the stack and the variable values ? Thanks 回答1: As far as I know, there is no known method to obtain a full core dump file for iOS apps that you can later load on GDB. Are you already asking your testers to

But each UItableVIew consists of

问题 I use Matt Gallagher's audio streamer for streaming radio stations. But how to record the audio? Is there a way to get the downloaded packets into NSData and save it in an audio file in the documents folder on the iPhone? Thanks 回答1: Yes, there is and I have done it. My problem is being able to play it back IN the same streamer (asked elsewhere). It will play back with the standard AVAudioPlayer in iOS. However, this will save the data to a file by writing it out in the streamer code. This
