I m using facebook SDK v3.11.1, and I have 2 facebook applications (on facebbok), each one has app ID.

I change the default app ID programmatically:

[FBSettings setDefaultAppID:<my_app_id>];

and then I invoke openActiveSessionWithReadPermissions, the facebook ask for permission to the relevant application.

After that i try to change the default app ID (same code as above) at the same session, and the facebook doesn't ask or permissions.

Should I close the old session, change the default app ID and reopen a new session?

Thanks in advance.

The FBSession object is used to authenticate a user and manage the user's session. After initializing a FBSession object the Facebook App ID and desired permissions are stored. Opening the session will initiate the authentication flow after which a valid user session should be available and subsequently cached. Closing the session can optionally clear the cache. If an request requires user authorization then an FBSession object should be used.

appID

Identifies the Facebook app which the session object represents. @property (readonly, copy) NSString *appID;
