Ios 成功登录后，PFLoginViewController将重新出现

我正在使用Parse的LoginViewController，在登录或注册成功后，它会关闭登录屏幕，只是立即将其恢复，而不是继续下一个ViewController。我确信登录成功

DefaultSettingsViewController.m：

- (void)viewDidLoad

{

    [super viewDidLoad];

// Do any additional setup after loading the view.

}



- (void)viewDidUnload

{

    [super viewDidUnload];

    // Release any retained subviews of the main view.

}



- (void)viewWillAppear:(BOOL)animated {

    [super viewDidLoad];

    if ([PFUser currentUser]) {

        //[welcomeLabel setText:[NSString stringWithFormat:@"Welcome Back %@!", [[PFUser currentUser] username]]];

        NSLog(@"PFUser is not current user");



    } else {

        NSLog(@"PFUser is current user");

        //[welcomeLabel setText:@"Not logged in"];

    }

}



- (void)viewDidAppear:(BOOL)animated {

    [super viewDidAppear:animated];



    PFLogInViewController *login = [[PFLogInViewController alloc] init];

    login.fields = PFLogInFieldsUsernameAndPassword | PFLogInFieldsLogInButton | PFLogInFieldsTwitter | PFLogInFieldsFacebook | PFLogInFieldsSignUpButton | PFLogInFieldsPasswordForgotten;

    login.delegate = self;

    login.signUpController.delegate = self;

    [self presentModalViewController:login animated:YES];





    if (![PFUser currentUser]) { // No user logged in

        // Create the log in view controller

        PFLogInViewController *logInViewController = [[PFLogInViewController alloc] init];

        [logInViewController setDelegate:self]; // Set ourselves as the delegate



        // Create the sign up view controller

        PFSignUpViewController *signUpViewController = [[PFSignUpViewController alloc] init];

        [signUpViewController setDelegate:self]; // Set ourselves as the delegate



        // Assign our sign up controller to be displayed from the login controller

        [logInViewController setSignUpController:signUpViewController];



        // Present the log in view controller

        [self presentViewController:logInViewController animated:YES completion:NULL];

    } else {

        [self performSegueWithIdentifier:@"login" sender:self];

    }



}

为什么要创建两个PfLoginView控制器实例？首先登录，以modalview的形式显示，然后，如果用户未登录，则创建另一个登录到的LoginView控制器

您似乎一直在使用解析登录教程，但他们不像您那样创建了两次

您还需要实现

- (void)logInViewController:(PFLogInViewController *)logInController didLogInUser:
