Is there a way to know with FACEBOOK SDK 3.1 and iOS 6 if the user has defined his facebook account in the iPhone settings for native facebook use?
What I want to do is when opening my app, if the user has defined a "native facebook account" in iPhone setting, immediately show the "allow/don't allow" iOS 6 alert. But I want to do it only for native integration. What I mean, is that if know I can just try an "openSession" with FBSession, and it will show it, but if user has not defined the native account, I don't want the app to go to Safari or the facebook app. So I want to try to connect only if user has defined an account.
anyone knows a way to know?
