Facebook sdk: ActiveSession is still closed after I give permission

I am integrating facebook login in my application. I jsut want the user to be able to login and I get his birthday and Location.

I got the latest Facebook SDK and successfully added it to my application. I also created a new application on facebook and added the key provided to my application.

I have created a button "Login with facebook" and done the following

When the user clicks the button

// handler for button click
- (IBAction)facebookLoginTouched:(id)sender {
    [self openSessionWithAllowLoginUI:YES];
}

This method will show the user the facebook login page in order to get his permission

-(BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
    NSArray *permissions = [[NSArray alloc] initWithObjects:
                            @"user_location",
                            @"user_birthday",
                            nil];
    return [FBSession openActiveSessionWithReadPermissions:permissions
                                          allowLoginUI:allowLoginUI
                                     completionHandler:^(FBSession *session,
                                                         FBSessionState state,
                                                         NSError *error) {
                                         [self HandleLogin];
                                     }];
}

Then if login and permission successful

- (void)HandleLogin {
    if (FBSession.activeSession.isOpen) {
        //THIS IS NEVER REACHED

        [FBRequestConnection
         startForMeWithCompletionHandler:^(FBRequestConnection *connection,
                                       id<FBGraphUser> user,
                                       NSError *error) {
             //DO SOMETHING WITH THE USER INFO
         }];
    }
}

My problem:

When I click on the button the facebook page comes in correctly and I enter my username/password. It logged me correctly and I gave permission for the application to access my information. When I finish, I return to the app successfully.

However when the code reaches FBSession.activeSession.isOpen it returns false.

Why is the session still closed after I correctly logged in and gave permission?

Any help is greatly appreciated.

Thanks

You may be missing code to process the return from the Facebook app. Add the following in your app delegate implementation file:

- (BOOL)application:(UIApplication *)application 
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    // attempt to extract a token from the url
   return [FBSession.activeSession handleOpenURL:url]; 
}
