title: Explicitly disabling UIView animation in iOS4+
body: <p>I have been reading that Apple recommends to use block-based animations instead of CATransaction</p>
  
  <p>Before, I was using this code to disable animations:</p>
  
  <pre><code>[CATransaction begin];
  [CATransaction setDisableActions: YES];
  // !!! resize
  [CATransaction commit];
  </code></pre>
  
  <p>Is there a new recommended method to do this, or is this still okay?</p>
