IBAction not responding to touch

[Whitehk]

I've created several apps using buttons, so I know this should be working. The deal is I'm trying to make a mute button to stop sound from playing. I don't get any errors when I compile, but when I load the app in the stimulator or on the phone, it doesn't do anything when I press the mute button. Here is how I implemented it:

Where I made the sound start playing:

- (void)viewDidLoad {
NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource: @"Background Music" ofType: @"wav"];
NSURL *backgroundMusicURL = [[NSURL alloc] initFileURLWithPath:backgroundMusicPath];
AVAudioPlayer *backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:nil];
[backgroundMusic play];
backgroundMusic.numberOfLoops = -1;
}

The IBAction I used to stop the sound:

-(IBAction)muteTheSound:(UIButton *)button {
NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource: @"Background Music" ofType: @"wav"];
NSURL *backgroundMusicURL = [[NSURL alloc] initFileURLWithPath:backgroundMusicPath];
AVAudioPlayer *backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:nil];
[backgroundMusic stop];
}


I know it's not a problem of connecting the button to the action in IB because I made SURE (100%) that I connected it correctly. Did I stop the music incorrectly? Is [backgroundMusic stop]; not what I should be using to stop the sound in this situation? Any replies would be appreciated. Thanks!

NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource: @"Background Music" ofType: @"wav"];
NSURL *backgroundMusicURL = [[NSURL alloc] initFileURLWithPath:backgroundMusicPath];
AVAudioPlayer *backgroundMusic = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:nil];
[backgroundMusic play];
backgroundMusic.numberOfLoops = -1;
}

I think you should keep the reference of the backgroundMusic AVAudioPlayer you initaited in viewDidLoad, and stop the playing of this particular player in the IBAction function

If I do this, it will then give me an error saying backgroundMusic undeclared. I am at a complete loss here.

Did you declare backgroundMusic as a member variable of your viewController?

Don't use IB. Wire up the events manually, then come back and report your findings.
