title: how to copy files to Library or Document dir in iphone build phase?
body: <p>I want copy some files to <code>Library</code> or <code>Document</code> in the <strong>Product directory</strong>,
  but when I add a build phase and select <strong>Products Directory</strong> in <em>destination</em> and <em>input</em> my subdir it's like <code>Library/xxx/</code>.</p>
  
  <p>When I run the App in the simulator, I found nothing in the <em>destination</em> and if I set the <em>destination</em> to <code>Resources</code>, it will be there.</p>
  
  <p>Can you please tell me why this is happening and how I can make it?</p>
