title: How to disable CALayer implicit animations?
body: <p>It's driving me crazy! I am working on a drawing application. Let's say I am working on a <code>UIView</code> called sheet.</p>
  
  <p>I am adding some sublayers to this view (<code>[sheet.layer addSublayer:...]</code>) and then I want to draw into them. To do so I am creating a <code>CGImageRef</code> and putting it into the layer's <code>contents</code>. But it's animated and I don't want that.</p>
  
  <p>I tried everything:</p>
  
  <ul>
  <li><code>removeAnimationForKey:</code></li>
  <li><code>removeAllAnimations</code></li>
  <li>set the actions dictionary</li>
  <li>using the actionlayer <code>delegate</code></li>
  <li><code>[CATransaction setDisableAnimations:YES]</code></li>
  </ul>
  
  <p>It's seems correct. I don't understand why this layer is still animated ;_;<br>
  Am I doing something wrong? Is there a secret way?</p>
