=== How to reset the button automatically after the audio stops ===

Dear DeltaClanOfficial,

I am glad you asked! This is a very easy process.

Go to your .h file and right under "IBOutlet UIButton *start;", create a new line and add the following before the ' } ':
NSTimer *timer;

Now go to your .m file. Look for "audioPlayer.numberOfLoops = X;" (X being whatever you set). Create a line BELOW that and add:

int timeTillStop = audioPlayer.duration;

timer = [NSTimer scheduledTimerWithTimeInterval:timeTillStop target:self selector:@selector(stop) userInfo:nil repeats:FALSE];

Ok, now we have a timer set to run the selector "stop" after waiting the length of the audio.

Right below "[audioPlayer release];", on a separate line add:
[timer release];

Right above "- (void)dealloc", add:

- (void)stop {
[start setTitle:@"Start" forState:UIControlStateNormal];
clicked = 0;
}

There you go! Just press RUN and it should work.

If you have any problems, just tell me.
