Expired access token after openActiveSession for Facebook iOS SDK

Question

I\'m using the 3.1 Facebook SDK with iOS 6 Facebook set up in Settings and my app authorized.

This executes flawlessly:

[FBSession openActiveSessionW         


        

Answer 1

So it's addressed, but I've been calling /me from our backend to verify since you can't trust the device.

So I make a call to FBSession's + (void)renewSystemAuthorization when the backend comes back with an authorization error.
