I am creating a music player application and it need that 2 actions to be called from a single button, one to skip to next track by touch up inside event and other to fast forward the curenttrack incase of a 'long press'.

The only way around this I could find was the pause the specific AVAudioPlayer instance in: applicationWillResignActive I moved the creation of the

I've developed an iPhone application that allows other apps to play audio in the background. To achieve this, I initialize my audio session like this: [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil]; At some point in my application I provide an audio player to play some files stored in CoreData with AVAudioPlayer. When the user hits the play button, the background audio should be paused. When the player has finished or is paused, the background audio should resume playback. While resuming after the player has finished playback with -(void
