title: Detecting touches on a UISlider?
body: <p>I have a UISlider on screen, and I need to be able to detect when the user stops touching it. (so I can fade some elements away).</p>
  
  <p>I have tried using:</p>
  
  <p><code>- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event</code> </p>
  
  <p>but this did not work when ending touches on a slider.</p>
