title: iPhone, hook for edit/done button click in table view
body: <p>In my table view controller there is</p>
  
  <pre><code>self.navigationItem.leftBarButtonItem = self.editButtonItem;
  </code></pre>
  
  <p>which produces a regular edit/done button at the top left corner. Hence, once the user clicks "Edit", the button caption changes to "Done" and the table entries may be deleted or reordered. I would like to get notified once the user actually clicks "Done". Is there a hook for that?</p>
  
  <p>Background: I'd like to persist the order of the entries i.e. next time the user pulls up this view I'd like to present the entries in the least recently used order.</p>
