Sound overlapping with multiple button presses

Question

When I press a button, then press another one, the sounds overlap. How can I fix that so the first sound stops when another one is pressed?

 - (void)playOnce         


        

Answer 1

In your playOnce method the 'path' variable is unused -- remove that to get rid of your warning message. Your playOnce does not set anything up to play so I'm not sure how that is supposed to work -- unless you call playLooped first? You also need to be calling prepareToPlay after the initWithContentsOfUrl.

 - (void)playOnce:(NSString *)aSound {

  NSString *path = [[NSBundle mainBundle] pathForResource:aSound ofType:@"caf"];
  if (theAudio && [theAudio isPlaying]) {
    [theAudio stop]
  } else {
         theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL: [NSURL fileURLWithPath: path] error: NULL];
         [theAudio prepareToPlay];

         [theAudio setDelegate: self];
    [theAudio setNumberOfLoops: 1];
    [theAudio setVolume: 1.0];
    [theAudio play];
  }

}
