AVAudioPlayer not playing any sound

I found the solution and it's related to something I didn't mention and didn't think about: I'm compiling with Automatic Reference Counting (ARC).

ARC inserts a release call to the audio player, so it's deallocated right after leaving the method where it is created. It has nothing to do with AVAudioPlayer but with ARC.

In order to solve this issue, I just created an AVAudioPlayer attribute to the class that deals with sounds so that it is not released anymore by ARC. Well, at least, it's not released until the instance of this class is released.

For more information about ARC, refer to Automatic Reference Counting: Zeroing Weak References with details on why I had this issue.

Yes, absolutely; ARC was the reason with my code as well.

I introduced a property:

@property (strong, nonatomic) AVAudioPlayer *audioPlayer;

and that made everything work out fine.
