title: Clear a delegate
body: <p>What is the correct way to clear a UIWebView delegate ?</p>
  
  <p>In my dealloc function, I added </p>
  
  <pre><code>[myWebView setDelegate:nil];
  [myWebView release];
  </code></pre>
  
  <p>And is the first ligne necessary ?</p>
  
  <p>EDIT : and what if my object was not a UIWebView but a <code>NSFetchedResultsController</code> ?</p>
  
  <p>Thanks</p>
