Problem with wav loops that stop working after awhile.

[8bitninja]

So, my problem is that after turning on and off my sound looping button several times, it eventually stops producing sound. I'm kind of at a dead end with this. So, if theres any new terms that you could sugest I look up or anything that could help me find my way would be greatly appreciated. Thanks again and I'll post my code below.


///MainView.h
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <AVFoundation/AVFoundation.h>

@interface MainView : UIView {

IBOutlet UIButton *soundbutton1;
IBOutlet UIButton *soundbutton2;

AVAudioPlayer*sound1;

}
-(IBAction)start;
-(IBAction)stop;

@end


///MainView.m

@implementation MainView


-(IBAction)start{

soundbutton1.hidden = TRUE;
soundbutton2.hidden = FALSE;


NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/sound1.wav", [[NSBundle mainBundle] resourcePath]]];

NSError *error;
sound1 = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
sound1.numberOfLoops = -1;

if (sound1 == nil)
NSLog([error description]);
else
[sound1 play];



}

-(IBAction)stop{

soundbutton1.hidden = FALSE;
soundbutton2.hidden = TRUE;

[sound1 stop];

}

@end

Ok, so i found that if I add [sound1 release]; to my stop loop action it totally fixes the stoping problem, like so.


-(IBAction)stop{

soundbutton1.hidden = FALSE;
soundbutton2.hidden = TRUE;

[sound1 stop];
[sound1 release];


}
But now the problem I'm having, is whenever I press my back button my app crashes. here is the code.


-(IBAction)goback{
[UIView beginAnimations:Nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFl ipFromLeft forView:self cache:YES];
[view2 removeFromSuperview];
[self addSubview:view1];
[UIView commitAnimations];

soundbutton1.hidden = FALSE;
soundbutton2.hidden = TRUE;

[sound1 stop];
[sound1 release];

}
Any tips would be very much appreciated, Thanks.
