从 xib 而不是主场景切换到情节提要中的场景

Question

我正在尝试实现一个包含主登录页面（在 Storyboard 中实现）的应用程序，它将用户引导到 UIWebView（在 xib 中实现）。登录成功后，我希望应用程序从 xib 返回到特定场景（由 Segue 连接），而是返回到主场景。

我从以下链接获得了帮助，但是我仍然遇到同样的问题： How to load a scene in a storyboard from a view controller 和 Add subview from a xib or another scene with storyboard

我的主视图控制器如下所示：

- (IBAction)loginButton:(id)sender

{

    oAuthLoginView = [[OAuthLoginView alloc] initWithNibName:nil bundle:nil];
    [oAuthLoginView retain];

    // register to be told when the login is finished
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(loginViewDidFinish:)
                                                 name:@"loginViewDidFinish"
                                               object:oAuthLoginView];

    [self presentModalViewController:oAuthLoginView animated:YES];
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
   UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    UINavigationController *navigationController = [self.storyboard instantiateViewControllerWithIdentifier:@"check2"];
//    SecondViewController *viewController = navigationController.viewControllers[0];
//    
//    // setup "inner" view controller
//   // viewController. = bar;
//    
//    [self presentViewController:navigationController animated:YES completion:nil];

}


-(BOOL) loginViewDidFinish:(NSNotification*)notification
{

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

    return YES;


  // [self performSegueWithIdentifier:@"mainApp" sender:self];


    // UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    //  ProfileTabView * yourView = (ProfileTabView *)[storyboard instantiateViewControllerWithIdentifier:@"segueID"];
    //   [self.presentedViewController:yourView animated:YES completion:^{}];

    //[self switchToStoryBoard];
}

我尝试了很多不同的方法（在此处的代码中进行了注释），但它要么导致应用程序崩溃，要么返回主登录屏幕。

我错过了什么？

任何帮助表示赞赏:)

Answer 1

Check2 *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"check2"];
    [self.navigationController pushViewController:viewController animated:YES];

'Check2' 应该是您的视图控制器。 这就是我在我的应用中所做的。
