title: How to repeat an action while MenuItem button is held down? (cocos2d)
body: <p>How to repeat an action while MenuItem button is held down?
  I tried to make a subclass on CCMenuItemImage and made</p>
  
  <pre><code>@implementation CCMenuItemSpriteHoldable
  
  @synthesize buttonHeld;
  
  -(void) selected
  {
  [super selected];
  buttonHeld = true;
  }
  -(void) unselected
  {
  [super unselected];
  buttonHeld = false;
  }
  
  @end
  </code></pre>
  
  <p>and put this on my init</p>
  
  <pre><code>CCMenuItem *upButtonItem = [CCMenuItemSpriteHoldable
                              itemFromNormalImage:@"up.png" selectedImage:@"upsel.png"
                              target:self selector:@selector(upButtonTapped:)];
  </code></pre>
  
  <p>but it did nothing... :(
  it just loads the (void) upButtonTapped when I release the button.
  is there any way to make a button that allows u to hold down?</p>
  
  <p>Thank you</p>
