title: UIControlEventTouchUpInside not called after separate touch event
body: <p>I have an interface where you can hold a button down with one hand, and manipulate settings with the other hand via a pan gesture or a pinch gesture.</p>
  
  <p>The problem is that the <code>UIControlEventTouchUpInside</code> callback for my button is never called after one of the other gestures. If I only push and release the button, the callback runs ok, but if I push it, then drag with another finger, and then release it, the callback is silent.</p>
  
  <p>Is there anyway for gestures recognizers and control events to be compatible?</p>
