Xamarin IOS导航到xamarin上没有按钮的另一个视图控制器

Question

我开始使用xamarin创建ios软件。 在主板中，我将PageMain视图控制器导航到PageTo视图控制器。 我想从PageMain视图控制器导航到PageTo视图控制器。 我使用此代码，但没有自动导航：

var storyBoard = UIStoryboard.FromName ("MainStoryboard", null);
storyBoard.InstantiateViewController ("PageTo");

也尝试过这个，但也不能自动导航：

PageMainViewController *viewController = segue. PageToViewController;
viewController.delegate = self;

也尝试过这个，但也不能自动导航：

UIViewController pageto = new PageTo ();
pageto.Transition (PageMain, PageTo);

我知道，它更易于使用按钮来创建到PageTo视图控制器的推序列，但我不想要它。 请帮我。

Answer 1

我希望这会有所帮助，我只需要这样做。

// Clear your notifications and other things

    // Show the controller
    // I am assuming your are using storyboards based in your use of Handle. I am also assuming the identifier in your storyboard for this is set to "WebViewController and its a custom subclass of UIViewController named WebViewController.

    UIStoryboard Storyboard = UIStoryboard.FromName ("MainStoryboard", null); // Assume the name of your file is "MainStoryboard.storyboard"

    var webController = Storyboard.InstantiateViewController("WebViewController") as WebViewController;
    // ... set any data in webController, etc.

    // Make it the root controller for example (the first line adds a paramater to it)
    webController.CaseID = int.Parse(notification.UserInfo["ID"].ToString());
    this.Window.RootViewController = webController;

    // Note* the "Window" should already be set and created because the app is running. No need to remake it.

您可以做的另一件事是推送到另一个视图控制器。

AssignCaseController assignCaseController = this.Storyboard.InstantiateViewController("AssignCaseController") as AssignCaseController;
if (assignCaseController != null)
{
    assignCaseController.CaseID = GetCurrentCaseID();
    this.NavigationController.PushViewController(assignCaseController, true);
}
