title: Graph API iOS picture
body: <p>I have a graph api call from my ios application.  It looks something like this:</p>
  
  <pre><code>[[appDelegate facebook] requestWithGraphPath:[NSString stringWithFormat:@"%i/picture", [[userData objectForKey:@"id"] intValue] andDelegate:self];
  </code></pre>
  
  <p>(might be some typos)</p>
  
  <p>But in the request did load when i nslog the result, it is <code>(null)</code>.  Graph API says that you need to use fields=picture or something to get the url.  How would I do this?  If it is possible could somebody show me some example code?</p>
