title: Facebook SDK share always returns sharerDidCancel
body: <p>I'm trying to share a post with the Facebook SDK, but sharerDidCancel is always called, either if I share or cancel the post.
  Here is my code</p>
  
  <pre><code>- (void)shareFacebook {
      FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
      content.contentURL = [NSURL URLWithString:@"http://www.google.com"];
      [FBSDKShareDialog showFromViewController:view
                                   withContent:content
                                      delegate:self];
  }
  
  - (void)sharer:(id&lt;FBSDKSharing&gt;)sharer didCompleteWithResults :(NSDictionary*)results {
      NSLog(@"FB: SHARE RESULTS=%@\n",[results debugDescription]);
  }
  
  - (void)sharer:(id&lt;FBSDKSharing&gt;)sharer didFailWithError:(NSError *)error {
      NSLog(@"FB: ERROR=%@\n",[error debugDescription]);
  }
  
  - (void)sharerDidCancel:(id&lt;FBSDKSharing&gt;)sharer {
      NSLog(@"FB: CANCELED SHARER=%@\n",[sharer debugDescription]);
  }
  </code></pre>
  
  <p>This class implements the FBSDKSharingDelegate, in my Info.plist I already entered the FacebookAppID and FacebookDisplayName.</p>
  
  <p>In my AppDelegate I have this method:</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
  {
      return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];
  }
  </code></pre>
  
  <p>What I'm doing wrong? I exactly followed the Facebook SDK guide.</p>
  
  <p>Thanks</p>
