Facebook SDK 3.1 - Error validating access token
In my app I have a delete account option. When used it tells our server to delete the account and it removes the app from the user's App Center. I also call [[FBSession activeSession] closeAndClearTokenInformation]. Even if I delete the iOS application and reinstall it I continue to get the old access token which obviously doesn't work since the Facebook app doesn't even exist any more. This is happening when I'm using native login in iOS 6 through the new SDK. The only way I can get a fresh/working token is to go into the Settings.app and disable Facebook access to my app then reenable it. At that point I finally get a new token (as well as an alert asking the user if they want to give the app permission to open).
How can I really clear/reset the token that iOS is holding onto?
