POHow to have a music on/off setting objective-c

copied!<p>I am making a simple game in cocos2d and I wanted to make a simple button toggle to keep sounds on or off. This is what I did so far...</p> <p>In my <code>.h</code>:</p> <pre><code>CCMenuItemImage *sound; CCMenu *menu2; </code></pre> <p>In my <code>init</code>:</p> <pre><code>[[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:@"musicon"]; // Sound Buttons sound = [CCMenuItemImage itemWithNormalImage:@"music.png" selectedImage:@"music.png" target:self selector:@selector(turnOffSound)]; sound.scale = 1.1; menu2 = [CCMenu menuWithItems:sound, nil]; menu2.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menu2]; </code></pre> <p>And then my <code>turnOffSound</code> and <code>turnOnSound</code> method:</p> <pre><code>-(void) turnOnSound { [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:@"musicon"]; [self removeChild:sound cleanup:YES]; [self removeChild:menu2 cleanup:YES]; sound = [CCMenuItemImage itemWithNormalImage:@"music.png" selectedImage:@"music.png" target:self selector:@selector(turnOffSound)]; sound.scale = 1.1; menu2 = [CCMenu menuWithItems:sound, nil]; menu2.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menu2]; } -(void) turnOffSound { [[NSUserDefaults standardUserDefaults] setBool:FALSE forKey:@"musicon"]; [self removeChild:sound cleanup:YES]; [self removeChild:menu2 cleanup:YES]; sound = [CCMenuItemImage itemWithNormalImage:@"music-not.png" selectedImage:@"music-not.png" target:self selector:@selector(turnOnSound)]; sound.scale = 1.1; menu2 = [CCMenu menuWithItems:sound, nil]; menu2.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menu2]; } </code></pre> <p>Right now, the toggle works but only on this screen (this is the title screen), because when I go to another screen, then go back to the title screen, the BOOL is being set to true again. Do you know how I can make it not reset again? Any help is appreciated, thank you!</p>
