avaudioplayer stops playing immediately with arc


avaudioplayer stops playing immediately with arc  using -'objective-c,ios,avfoundation,avaudioplayer,automatic-ref-counting'

I am trying to play an MP3 via AVAudioPlayer which I thought to be fairly simple. Unfortunately, it's not quite working. Here is all I did:


For the sake of testing, I created a new iOS application (Single
View) in Xcode.
I added the AVFoundation framework to the project as well as the #import
<AVFoundation/AVFoundation.h> to the ViewController.m
I added an MP3 File to the Apps 'Documents' folder.
I changed the ViewControllers viewDidLoad: to the following:


Code:

- (void)viewDidLoad
{
    [super viewDidLoad];        

    NSString* recorderFilePath = [NSString stringWithFormat:@"%@/MySound.mp3", [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]];    

    AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:recorderFilePath] error:nil];
    audioPlayer.numberOfLoops = 1;

    [audioPlayer play];

    //[NSThread sleepForTimeInterval:20];
}


Unfortunately, the audio obviously stops right after it starts playing. If I uncomment the sleepForTimeInterval it plays for 20 seconds and stops afterwards. This problem occurs only when compiling with ARC, otherwise, it works flawlessly.
