AVAudioPlayer audioPlayerDidFinishPlaying called when the file is played second time - ios

Question

I am using AVAudioPlayer class to play audio but the problem is that when I play the audio I do not receive the callback in audioPlayerDidFinishPlaying when the file is finish playing and the file starts again even when the number of loops is set to 1
Here is the code.
.h
#interface AudioController : NSObject <AVAudioPlayerDelegate>
-(void) playBigGameTheme{
-(void) playMusic:(NSString*) fileName isLooping: (BOOL) isLooping;
#end
.m
#implementation AudioController{
AVAudioPlayer *audioPlayer;
}
-(void) playMusic:(NSString*) fileName isLooping: (BOOL) isLooping{
int loop = 1;
if(isLooping){
loop = -1;
}
[audioPlayer stop];
NSURL* soundUrl = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:#"mp3"]];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundUrl error:nil];
audioPlayer.numberOfLoops = loop;
[audioPlayer setDelegate:self];
NSLog(#"===Number of loops : %d", audioPlayer.numberOfLoops);
[audioPlayer play];
}
- (void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
NSLog(#"HERE");
}
-(void) playBigGameTheme{
[self playMusic:BGAME_MAIN_MUSIC_FILE_NAME isLooping:NO];
}
#end
when I call playBigGameTheme the audio starts playing correctly. but it restarts when the sound is finished and when the audio finishes the second time then only the audioPlayerDidFinishPlaying method is called.
I am stuck and do not know whats going wrong..

Answer 1

even when the number of loops is set to 1
That's exactly why. The name and the behavior of this property is a bit counter-intuitive, but if you had read the documentation, it would have been clear that it sets the number of repetitions, and not the number of playbacks. Quote from the docs:
The value of 0, which is the default, means to play the sound once.
So set it to 0 (or don't set it, zero is the default value) and it will play the audio file only once:
audioPlayer.numberOfLoops = 0;
