如何处理facebook对话框apprequest的取消按钮？

Question

As you know, you can display some facebook views to make some operations, like app requests, post etc. There is a delegate to manage the callbacks like : dialogDidComplete: , dialogDidNotComplete: . The view is like that :

But there is not differentiation between the cancel and share button. You will have the same callback in dialogDidComplete: . The only way to manage a cancelation is the little cross in the corner. In my case I would like to do some operations if the user pressed share and not when he pressed Cancel. The private social network Path manage this case and I'm wondering how ?

Do you guys have some ideas ?

Answer 1

If I am not wrong:

• if you press Share you get a requestID back as part of the returned URL

• if you press Cancel you are returned into dialogDidComplete but it does not return a requestID back as part of the returned URL.

Code:

- (void)dialogCompleteWithUrl:(NSURL *)url {
     if (![url query]) {
         NSLog(@"User canceled dialog or there was an error");
         return;
     }
  }
