title: Use UISlider without user interaction
body: <p>I've got a customized UISlider that I want to use to display information to the user with and I don't want the user to be able to interact with the slider. I've tried</p>
  
  <pre><code>mySlider.enabled = NO;
  </code></pre>
  
  <p>but the slider becomes greyed out, which does not look the way I want it to look.</p>
  
  <p>So, how do I set a UIControl to disabled without "greying" it out.</p>
