Mvvmcross - 容器UIViewController(Mvvmcross - Container UIViewController)

 我正在尝试实现一个Custom UIViewController类，它将充当我的导航控制器，而不是使用默认的导航控制器。 下面是我的容器类： 
 
 enter code here public partial class ContainerView：MvxViewController {static bool UserInterfaceIdiomIsPhone {get {return UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Phone; }} 
 
    private UIViewController _currentView;

    protected ContainerViewModel ContainerModel
    { get { return base.ViewModel as ContainerViewModel; } }

    public ContainerView ()
        : base (UserInterfaceIdiomIsPhone ? "ContainerView_iPhone" : "ContainerView_iPad", null)
    {

    }



    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        var loginView = this.CreateViewControllerFor(ContainerModel.Login) as UIViewController;
        ShowViewController(loginView);
        // Perform any additional setup after loading the view, typically from a nib.
    }

    public ContainerView(UIViewController controller)
        : base(UserInterfaceIdiomIsPhone ? "ContainerView_iPhone" : "ContainerView_iPad", null)
    {
        ShowViewController(controller);
    }

    public void ShowViewController(UIViewController viewController)
    {
        if (_currentView !=null)
        {
            RemoveCurrentViewController();
        }

        AddChildViewController(viewController);
        viewController.View.Frame = GetViewFrame();
        containerView.AddSubview(viewController.View);
        _currentView = viewController;
        viewController.DidMoveToParentViewController(this);

    }

    public void RemoveCurrentViewController()
    {
        _currentView.WillMoveToParentViewController(null);
        _currentView.View.RemoveFromSuperview();
        _currentView.RemoveFromParentViewController();

    }

    public RectangleF GetViewFrame()
    {
        return containerView.Bounds;
    }
}
 
 我的第一次加载很好，因为登录视图被加载到containerView中，这是一个来自笔尖的插座。 问题是随后的请求我的插座是空的。 我可能做错了，但我试图在Presenter Show方法中设置viewcontroller，如下所示： 
 
public class MyPresenter: MvxTouchViewPresenter
    {
        private static ContainerView _cv;

        public BlackhawkPresenter(MvxApplicationDelegate appDelegate, UIWindow window)
            : base(appDelegate, window)
        {
            _cv = new ContainerView();
            window.RootViewController = _cv;
        }

        protected override UINavigationController CreateNavigationController(UIViewController viewController)
        {
            return new BlackhawkNavigationController(viewController);
        }

        public override void Show(Cirrious.MvvmCross.ViewModels.MvxViewModelRequest request)
        {
            var viewController = (UIViewController)Mvx.Resolve<IMvxTouchViewCreator>().CreateView(request);
            if(request.ViewModelType == typeof(ContainerViewModel))
                base.Show(request);
            else
                _cv.ShowViewController(viewController);

        }

    }
 
 对于show中的else语句，因为“ViewDidLoad”从不触发我的插座是null。 我不确定是否有任何阻止ShowViewModel将其显示在容器类容器View中的调用。 

I am trying to implement a Custom UIViewController class that will act as my navigation controller rather than using the default navigation controller. Below is my container class I have:
 
enter code herepublic partial class ContainerView : MvxViewController { static bool UserInterfaceIdiomIsPhone { get { return UIDevice.CurrentDevice.UserInterfaceIdiom == UIUserInterfaceIdiom.Phone; } }
 
    private UIViewController _currentView;

    protected ContainerViewModel ContainerModel
    { get { return base.ViewModel as ContainerViewModel; } }

    public ContainerView ()
        : base (UserInterfaceIdiomIsPhone ? "ContainerView_iPhone" : "ContainerView_iPad", null)
    {

    }



    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        var loginView = this.CreateViewControllerFor(ContainerModel.Login) as UIViewController;
        ShowViewController(loginView);
        // Perform any additional setup after loading the view, typically from a nib.
    }

    public ContainerView(UIViewController controller)
        : base(UserInterfaceIdiomIsPhone ? "ContainerView_iPhone" : "ContainerView_iPad", null)
    {
        ShowViewController(controller);
    }

    public void ShowViewController(UIViewController viewController)
    {
        if (_currentView !=null)
        {
            RemoveCurrentViewController();
        }

        AddChildViewController(viewController);
        viewController.View.Frame = GetViewFrame();
        containerView.AddSubview(viewController.View);
        _currentView = viewController;
        viewController.DidMoveToParentViewController(this);

    }

    public void RemoveCurrentViewController()
    {
        _currentView.WillMoveToParentViewController(null);
        _currentView.View.RemoveFromSuperview();
        _currentView.RemoveFromParentViewController();

    }

    public RectangleF GetViewFrame()
    {
        return containerView.Bounds;
    }
}
 
My first load is fine as the login view is loaded into the containerView which is an outlet from the nib. The problem is on subsequent request my outlet is null. I may be doing this wrong but I am attempting to set the viewcontroller in the Presenter Show method as per below:
 
public class MyPresenter: MvxTouchViewPresenter
    {
        private static ContainerView _cv;

        public BlackhawkPresenter(MvxApplicationDelegate appDelegate, UIWindow window)
            : base(appDelegate, window)
        {
            _cv = new ContainerView();
            window.RootViewController = _cv;
        }

        protected override UINavigationController CreateNavigationController(UIViewController viewController)
        {
            return new BlackhawkNavigationController(viewController);
        }

        public override void Show(Cirrious.MvvmCross.ViewModels.MvxViewModelRequest request)
        {
            var viewController = (UIViewController)Mvx.Resolve<IMvxTouchViewCreator>().CreateView(request);
            if(request.ViewModelType == typeof(ContainerViewModel))
                base.Show(request);
            else
                _cv.ShowViewController(viewController);

        }

    }
 
for the else statement in the show as the "ViewDidLoad" never fires my outlet is null. I am not sure of any othe rway to intercept the call for ShowViewModel to display it in container View in my container class.
