I\'m having problems with my app saving the access_token. The problem is, when an iPhone hasn\'t the Facebook app installed, safari will handle this and there is no problem. But
Have you disabled multi-task on your app via Info.plist? The Facebook SDK makes the (undocumented assumption) that your app supports multi-task.
By that I mean you have a "Application does not run in background" (UIApplicationExitsOnSuspend) set to YES.
If that is the case, you're going to have to use login via an in-app browser for which I will update my post and provide a code sample.
