Trying to play sound on iPhone

Question

Ok this works

- (id)initWithCoder:(NSCoder*)coder
{
 if ((self = [super initWithCoder:coder]))
  {
   // Load the sounds
  NSURL *soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Begin Drawing" ofType:@"wav"]];
  AudioServicesCreateSystemSoundID((CFURLRef)soundURL, &_boomSoundIDs[0]);
  soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Middle Drawing" ofType:@"wav"]];
  AudioServicesCreateSystemSoundID((CFURLRef)soundURL, &_boomSoundIDs[1]);
  soundURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"End Drawing" ofType:@"wav"]];
  AudioServicesCreateSystemSoundID((CFURLRef)soundURL, &_boomSoundIDs[2]);  
  }
 return self;
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
 UITouch *touch = [touches anyObject];

 if ([touches count] == 1)
  {
  AudioServicesPlaySystemSound(_boomSoundIDs[0]);
 }

But this is what I am trying to fix

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{
if ([touches count] == 1)
  {
  AudioServicesPlaySystemSound(_boomSoundIDs[1]);
 }

It just plays so continuously that the sound will not play all the way through, but begin every time the user moves their finger, I want is to actually play all the way through then loop again

Answer 1

Before you play the sound, check to see if it's already playing.

Also please reformat your code, it's hard to read.

Answer 2

The system sound API is probably not the best pick for what you are trying to do. Take a look at AVAudioPlayer. The API is simple and it lets you check if the sound is already playing.
