title: viewdidunload is not getting called at all
body: <p>My problem is like this:</p>
  
  <ol>
  <li>Parent class loads a child view.</li>
  <li>Child removes itself during an action by using "removeFromSuperView".</li>
  <li>Parent class gets a delegate call when the child gets removed and hence makes the child object nil.</li>
  </ol>
  
  <p>Still the child class's viewdidunload is not called!</p>
