Update: Somehow the behaviour seems to have changed. I don\'t get the error message any more but the native login still does not work. Instead I am redirect
Perhaps you may be missing this method:
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { return [FBSession.activeSession handleOpenURL:url]; }
It helped my case in which I had to migrate from 3.9.0 to the latest. Hope it helps.
