 UIImage *image = [UIImage imageNamed:@"audio-off.png"]; 
     UIButton *myMuteButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
     myMuteButton.bounds = CGRectMake(0, 0, image.size.width, image.size.height);  
     [myMuteButton setImage:image forState:UIControlStateNormal]; 
     [myMuteButton addTarget:self action:@selector(mute) forControlEvents:UIControlEventTouchUpInside];  
     UIBarButtonItem *myMuteBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:myMuteButton]; 

     [buttons addObject:myMuteBarButtonItem]; 



     [myMuteBarButtonItem release];
