推荐答案

也许这段代码可以帮助你，把它放在你的 AppDelegate.m 类

Maybe this code helps you, put it in your AppDelegate.m class

- (void)sessionStateChanged:(FBSession *)session
                      state:(FBSessionState) state
                      error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen: {
            self.loggedinVCController = [[LoggedinVC alloc] initWithNibName:@"LoggedinVC" bundle:nil];
            self.navController = [[UINavigationController alloc]initWithRootViewController:self.loggedinVCController];
            self.window.rootViewControlle`enter code here`r = self.navController;

        }
            break;
        case FBSessionStateClosed:
        case FBSessionStateClosedLoginFailed:
            // Once the user has logged in, we want them to
            // be looking at the root view.
            [self.navController popToRootViewControllerAnimated:NO];

            [FBSession.activeSession closeAndClearTokenInformation];

            self.viewController = [[SampleViewController alloc] initWithNibName:@"SampleViewController" bundle:nil];
            self.window.rootViewController = self.viewController;

            break;
        default:
            break;
    }

    if (error) {
        UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"Error"
                                  message:error.localizedDescription
                                  delegate:nil
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [alertView show];
    }
}
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{
    return [FBSession.activeSession handleOpenURL:url];
}
- (void)openSession
{
    [FBSession openActiveSessionWithReadPermissions:nil
                                       allowLoginUI:YES
                                  completionHandler:
     ^(FBSession *session,
       FBSessionState state, NSError *error) {
         [self sessionStateChanged:session state:state error:error];
     }];
}
