iOS FBConnect access_token and resuming

I am using FBConnect in my iOS app, with the latest version of FBConnect-iOS.

The github docs claim that no "resume" function is available for fbconnect sessions because the developer is not responsible for storing the access_token information. Link Here

This 开发者_如何学运维is all well and good, and I can grab the access_token string using [_facebook access_token]; however, I can't figure out how to resume a session using this token so the user doesn't have to login every time the app is opened.

Does anyone know how to resume a session using the access_token key?

Many thanks! Brett

Just call [_facebook isSessionValid] the function to check the session.
