iOS：發送Facebook請求

Question

我已發送Facebook請求。它的工作正常，但我得到的請求（通知）只在iPhone的Facebook應用程序，而不是在Facebook的Web應用程序。我希望Facebook本地應用程序和Web應用程序都能收到通知。我怎樣才能做到這一點？

如果您的應用程序實施了Facebook Canvas應用程序，則只能在Facebook Web應用程序上獲得通知。

invitable_friends API僅適用於使用Graph API版本2.0的Facebook Canvas應用實現的遊戲 。

Check here the full documentation

Canvas是在把你的應用程序或遊戲直接在 Facebook.com上的臺式機和筆記本電腦的框架。

注意：在文檔中，你會發現「你的遊戲」，他們的意思是「您的遊戲或你的應用程序」。
