title: Another question about iPhone application state
body: <p>I have another question about restoring application state, on the iPhone.
  Simple data (like the selected tab) can be stored in NSUserDefaults, but it is not enough.</p>
  
  <p>I want to restore the whole state, including the Navigation Controllers (go to the sub-sub-sub View Controller).</p>
  
  <p>My problem is that my application is divided in several xib files, so at the beginning, all the View Controllers are not instantiated.
  Is there any way to "force" the instanciation from a xib file ?</p>
  
  <p>(I have no code under the hand, but I can try to write a small end if it is not clear)</p>
  
  <p>Thanks a lot.</p>
