title: UISearchBar Dismiss Method
body: <p>For a UISearchBar with UISearchDisplayController, when the searchfield is clicked, the keyboard appears and an overlay shows over the tableview.  When cancel is clicked</p>
  
  <pre><code>- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
  </code></pre>
  
  <p>is called.</p>
  
  <p>I am wondering if there is a method called when the overlay is clicked.  It does dismiss the keyboard and go back to the tableview.  Basically I want to make clicking this overlay run the same method as when cancel is clicked.  Any ideas?  I checked the Apple Docs and couldn't find anything other than the cancel button method.</p>
