xcoded mute button on toolbar to mute sound just of the App

I am brand new to iOS development. I have a simple 'clicker' app which makes a sound (mp3 file) every time you click an on screen button.

I want to implement a mute button which when selected:

  1. The button image changes (and stays changed until selected again)

  2. The sound of just the app is muted

  3. On selecting again returns to original state - sound on and previos button image

Here is how I'm playing my sound:

- (IBAction)click;


#import "soundButtonViewController.h"

@implementation soundButtonViewController

-(IBAction)click
{
   CFBundleRef mainBundle = CFBundleGetMainBundle();
   CFURLRef soundFileURLRef;
   soundFileURLRef =CFBundleCopyResourceURL(mainBundle, 
   (CFStringRef)@"click",CFSTR ("mp3"), NULL);
   UInt32 soundID;
   AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
   AudioServicesPlaySystemSound(soundID);
}

Is there any example code of this anywhere? I have done some research and there seems to be a few methods out there, but was wanting specific to my requirements. Any help or direction would be greatly appreciated. Thanks.

For changing the button, my usual way of doing this is to create a BOOL to keep track of the state of the button. In this case, the BOOL is "muteOn" and the IBOutlet for the Button is muteButton. Then, I use this code to control the button image and whether or not the app is muted. You can also put an if/then inside your click action (also shown below) to either play a sound or Do Nothing, if muteON is set to YES. Remember to declare your Bool in the .h file, too.

-(IBAction)muteToggle{

if (muteOn == YES) {
    muteOn = NO;
    UIImage *buttonImage = [UIImage imageNamed:@"muteOff.png"];
    [muteButton setImage:buttonImage forState:UIControlStateNormal];
}

else {
    muteOn = YES;
    UIImage *buttonImage = [UIImage imageNamed:@"muteOn.png"];
    [muteButton setImage:buttonImage forState:UIControlStateNormal];
}

}


-(IBAction) click {

 if (muteOn == YES){
//Do Nothing
 }

 else{
CFBundleRef mainBundle = CFBundleGetMainBundle();
CFURLRef soundFileURLRef;
soundFileURLRef =CFBundleCopyResourceURL(mainBundle, 
 (CFStringRef)@"click",CFSTR ("mp3"), NULL);
  UInt32 soundID;
 AudioServicesCreateSystemSoundID(soundFileURLRef, &soundID);
  AudioServicesPlaySystemSound(soundID);

}
}
