Xamarin.Forms棱鏡從導航堆棧刪除視圖堆棧

Question

是否可以從導航堆棧中刪除視圖？

這是我想什麼來實現：

• 導航可以看到
• 導航，查看2
• 導航，查看3

如果視圖3我推「回去」按鈕，我想去查看1.

Answer 1

Navigation.RemovePage(Navigation.NavigationStack.Last()); 
Navigation.PopAsync(); 

Answer 2

這應該工作

_navigationService.NavigateAsync("yourApp:///NavigationPage/YourPage") 

這相當於

MainPage = new NavigationPage(new YourPage()); 

注：我面臨崩潰問題iOS與導航這種方式。我解決它通過Device.RuntimePlatform

switch (Device.RuntimePlatform) 
{ 
    case Device.iOS: 
     _navigationService.NavigateAsync("YourPage"); 
     break; 
    case Device.Android: 
     _navigationService.NavigateAsync("yourApp:///NavigationPage/YourPage"); 
     break; 
    default: 
     _navigationService.NavigateAsync("YourPage"); 
     break; 
}
