title: cannot disable UIButton
body: <p>I have UIView > UIView > Custom UIButton with a simple image.<br>
  It is a refresh button that I need to hide while I am downloading and processing the xml file, so the user is not able to trigger the refresh multiple times.<br>
  This is the code I use to do that:  </p>
  
  <p>self.myRefreshButton.enabled = NO;<br>
  self.myRefreshButton.userInteractionEnabled = NO;<br>
  [self.myRefreshButton removeFromSuperview];  </p>
  
  <p>Unfortunately, it does not work. Although the button is removed, I am able to touch and trigger the button.</p>
  
  <p>Any ideas what I am doing wrong?</p>
