title: UIButton that will ignore a 'drag' and pass it to UIScrollView
body: <p>I know there are similar posts on Stack but nothing that I've found has helped me find a solution.</p>
  
  <ul>
  <li>I have a <strong>scrollview</strong> added to a <strong>UIView</strong>.</li>
  <li><p>I have added a <strong>UIButton</strong> to the <strong>same UIView above the scrollview</strong>.</p>
  
  <ol>
  <li>I want the UIButton to respond to a touchUp and fire an event.</li>
  <li>If someone <strong>DRAGS</strong> on the UIButton I want it to <em>pass the event to the scrollView and drag the UIScrollView without firing the button event.</em></li>
  </ol></li>
  </ul>
  
  <p>I know how to pass on a touch with hitTest returning the scrollview but this stops anything getting to the UIButton.</p>
  
  <p>I <strong>don't</strong> want to add the UIButton to the UIScrollView. </p>
  
  <p>Does anyone have a proposed solution?</p>
