title: How do you move a CALayer instantly (without animation)
body: <p>I'm trying to drag a <code>CALayer</code> in an iOS app.</p>
  
  <p>As soon as I change its position property it tries to animate to the new position and flickers all over the place:</p>
  
  <pre><code> layer.position = CGPointMake(x, y)
  </code></pre>
  
  <p>How can I move <code>CALayers</code> instantly? I can't seem to get my head around the Core Animation API.</p>
