title: UITapGestureRecognizer waiting for second tap, buttons slow
body: <p>I have a UITapGestureRecognizer waiting for a doubletap to zoom out an scrollview back to the original level. However there is a situation that I add a couple of buttons on top of the scrollview. These buttons react very slow (sluggishly) because once I tap a button, the app waiting for the second tap. If this does not come, the button is pressed.</p>
  
  <p>Anyone have an idea on how to get the buttons to respond quickly? Can I temporarily disable the GestureRecogniser while the buttons are up?</p>
  
  <p>Cheers
  Nick</p>
