I have 5 songs in my app that I would like to play one after the other with AVAudioPlayer.

Are there any examples of this? How can I accomplish this?

For every song you want to make make a single AVPlayer.

NSURL *url = [NSURL URLWithString:pathToYourFile];
AVPlayer *audioPlayer = [[AVPlayer alloc] initWithURL:url];
[audioPlayer play];

You can get a Notification when the player ends. Check AVPlayerItemDidPlayToEndTimeNotification when setting up the player:

  audioPlayer.actionAtItemEnd = AVPlayerActionAtItemEndNone; 

  [[NSNotificationCenter defaultCenter] addObserver:self
                                           selector:@selector(playerItemDidReachEnd:)
                                               name:AVPlayerItemDidPlayToEndTimeNotification
                                             object:[audioPlayer currentItem]];

this will prevent the player to pause at the end.

in the notification:

- (void)playerItemDidReachEnd:(NSNotification *)notification
{
    // start your next song here
}

You can start your next song as soon as you get a notification that the current playing song is done. Maintain some counter which is persistent across selector calls. That way using counter % [songs count] will give you an infinite looping playlist :)

Don't forget un unregister the notification when releasing the player.
