title: Referencing a button when the action's sender is a UIGestureRecognizer
body: <p>I've got a button called <code>myButton</code> and I gave it a <code>UIGestureRecognizer</code> so that an <code>IBAction</code> is only run when <code>myButton</code> is pressed with two fingers:</p>
  
  <pre><code>UIGestureRecognizer  *tapper = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(twoFingerTap:)];
  [(UITapGestureRecognizer *) tapper setNumberOfTouchesRequired:1];
  [newTaskButton addGestureRecognizer:tapper];
  </code></pre>
  
  <p>Prior to adding the gesture recognizer, I could use <code>sender</code> to reference the button that was just pressed, however now <code>sender</code> is now the gesture recognizer. I still need to reference the button that was pressed...Is there any way to go about doing so? An easy method that returns whatever is using the gesture recognizer maybe? Thanks!</p>
