我是iOS的新手。我正在使用下面的Xamarin组件创建SlideoutNavigation Menu。 Github链接如下。iOS中的MonoTouch.SlideoutNavigation注销问题（Xamarin）

链接：https://github.com/thedillonb/MonoTouch.SlideoutNavigation

这个组件中的整个事情是工作的罚款。但我有一个小问题。

最初我的LoginViewController看起来像这样。

截图：

有一个在左侧无菜单按钮。

现在，当我登录新开放屏幕与菜单是这个样子

截图：

现在，当打开时滑出式菜单，然后选择Logout选项我想开始我的LoginViewController它也使用下面的代码工作正常。

代码：

var loginViewController = storyboard.InstantiateViewController("ViewController") as ViewController; 
BizApplication.clearCredential(); 
StyledStringElement logout = new StyledStringElement("Logout",() => NavigationController.PushViewController(loginViewController, true)){ TextColor = UIColor.White, BackgroundColor = UIColor.Clear }; 
logout.Image = new UIImage("filter_icon.png");

，但现在我越来越下方未想屏幕。我想要移除导航中的左侧菜单图标。

截图：

任何帮助理解。

更新：

新的控制器开启推代码：

if (BizApplication.getCredential() != null) 
        { 
         window = new UIWindow(UIScreen.MainScreen.Bounds); 
         Menu = new SlideoutNavigationController(); 

         var webController2 = Storyboard.InstantiateViewController("SearchViewController") as SearchViewController; 
         NavigationController.PushViewController(webController2, true); 

         Menu.MainViewController = new MainNavigationController(webController2, Menu); 
         Menu.MenuViewController = new MenuNavigationController(new DummyControllerLeft(), Menu) { NavigationBarHidden = true }; 

         window.RootViewController = Menu; 
         window.MakeKeyAndVisible(); 

         loadingOverlay.Hide(); 
        }

我的流程：

我只用一个我的项目故事板。所以所有的ViewController都在同一个StoryBoard中。

部署信息：

AppDelegate.cs我不会改变这个文件什么。

SplashViewController。CS

    { 
     UIWindow window;

更新最新：

如果我这样做的DummyLeftControllers.cs那么没有什么是发生：

StyledStringElement logout = new StyledStringElement("Logout",() => CallthisMethod(storyboard)){ TextColor = UIColor.White, BackgroundColor = UIColor.Clear }; 
      logout.Image = new UIImage("filter_icon.png"); 


void CallthisMethod(UIStoryboard storyboard) 
     { 
      var vwControllers = NavigationController.ViewControllers; 

      foreach (UIViewController signiinVC in vwControllers) 
      { 
       if (signiinVC.GetType() == typeof(ViewController)) 
       { 
        this.NavigationController.PopToViewController(signiinVC, true); 
       } 
      } 

      BizApplication.clearCredential(); 

      NavigationController.PopToRootViewController(true); 

    }

你怎么推新屏幕完成登录时？你能分享代码吗？ – Darshana

@NinjaHattori查看我的更新代码。 – Ironman

@NinjaHattori如果你需要其他代码，然后告诉我，我会更新它。 – Ironman

你推退出堆栈SignInView控制器 - 这是不正确。编写代码的方式，它使用来自堆以前压看法..

在Splashviewconrtroller变化按照viewDidLoad方法：

base.ViewDidUnload(); 

      storyboard = UIStoryboard.FromName ("Main", null); 
      var webController = storyboard.InstantiateViewController ("ViewController") as ViewController; 
      this.NavigationController.PushViewController (webController, false); 


      if (Reachability.IsHostReachable ("http://google.com")) { 
       if (BizApplication.CheckCredential()) { 
        //window = new UIWindow (UIScreen.MainScreen.Bounds); 

        Menu = new SlideoutNavigationController(); 

        storyboard = UIStoryboard.FromName ("Main", null); 
        var webController = storyboard.InstantiateViewController ("SearchViewController") as SearchViewController; 

        NavigationController.PushViewController (webController, false); 

        Menu.MainViewController = new MainNavigationController (webController, Menu); 
        Menu.MenuViewController = new MenuNavigationController (new DummyControllerLeft(), Menu) { NavigationBarHidden = true }; 
        this.NavigationController.PushViewController (Menu); 
        //window.RootViewController = Menu; 
        //window.MakeKeyAndVisible(); 

       } 
      }

在Logout..Call如下：

void onLogOut (object sender, EventArgs e) 
     { 
    //Write your code to clear 
      var vwControllers = this.NavigationController.ViewControllers; 
     foreach(UIViewController signinVC in vwControllers) { 
      if (signinVC.GetType() == typeof (ViewController)) { 
       this.NavigationController.PopToViewController (ViewController); 
      } 
     } 

     }

等待我尝试解决方案并尽快回复给您。 – Ironman

我有liitle问题因为我在故事板中使用了'SpalshViewController'。 – Ironman

你能解释一下你有什么问题吗？ – Darshana

我认为你应该以模态方式呈现你的视图控制器，因为你不需要后退按钮，所以不需要将它们推入堆栈。

，而不是

navigationcontroller.pushviewcontroller()

使用

presentviewcontroller()

可以使用dismissviewcntroller()当注销，这将不会在登录屏幕改变你的导航栏
