title: How do I write ALAsset in a NSData
body: <p>I'm trying to write <code>ALAsset</code> in a <code>NSData</code> and somehow came up with the following code which does not work. What I would like to know is, whether the code is similar to this? Or is there another way of doing it?</p>
  
  <pre><code>NSData *data = [[NSData alloc] initWithContentsOfFile:@"assets-library://asset/asset.MOV?   id=100000009&amp;ext=MOV" ];
  </code></pre>
