I\'m using a pop up Facebook dialog for the user login and the publishing of a post on his/her stream
NSMutableDictionary* params = [NSMutableDictionary dict
I just had the same problem and solved it. You NEED to implement
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
in your app delegate class, not your custom UIViewController or any other class. Then direct the call from your app delegate to whatever controller is responsible for your Facebook.
