iOS facebook login ask for permission every time

Question

I'm using FBLoginView in my iOS app. I do everything like in this tutorial. Everything works great except one thing. When I logout and then login again via facebook it opens view with ask for grant permission to app with information I grant permission already. How can I skip this view after grant permission first time?

Answer 1

There are two ways to log out :

Closes the local in-memory session object, but does not clear the persisted token cache.

[[FBSession activeSession] close];

and

Closes the in-memory session, and clears any persisted cache related to the session.

[[FBSession activeSession] closeAndClearTokenInformation];

In your case, I think that using the first option rather than the second will keep your token, and you won't need to ask permission again.
