title: Facebook Login does not return to App with Xcode 7 iOS 9
body: <p>I have implemented this method for Facebook Login in the App Delegate using Xcode 7 and it works perfectly:</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary&lt;NSString*, id&gt; *)options {
  
  return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                        openURL:url
                                              sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                     annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
  }
  </code></pre>
  
  <p>However, since I need to use Xcode 6 to submit my app to the App Store, this method does not exists and it give me errors. </p>
  
  <p>If I comment the above method, and leave only the following:</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
  
  return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                        openURL:url
                                              sourceApplication:sourceApplication
                                                     annotation:annotation
          ];
  
  
  }
  </code></pre>
  
  <p>it will not work, that is, when the user tries to Login, it does not return to the Application.</p>
  
  <p>Is there an easy fix for this? Thanks!</p>
