title: UIApplication delegate method is not called
body: <p>I have a problem integrating Facebook SDK 3.2 with my app, my app goes to facebook app for approval and login, but when </p>
  
  <pre><code> - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation;
  </code></pre>
  
  <p>needs to be called when facebook authorization is done, it simply skips it. 
  It works great when I force webView facebook login via modal viewcontroller, but when I want to use installed facebook app/safari it just doesn't work.
  Any suggestions?
  Thank you.</p>
