I'm using Facebook iOS SDK 3.5 to log-in into my app, the following method is invoked:
FBSession openActiveSessionWithReadPermissions
If native iOS login is not enabled and facebook iOS app is installed, the login process will get redirected to the facebook app. The problem is that every single time 'FBSession openActiveSessionWithReadPermissions'is invoked, the facebook app presents the permission dialog to the user, even when the user already authorized the FB app.
The permission list is empty (nil). This problem does not happen if native ios or safari are used to log -in.
Any ideas? Thanks
