Xamarin形式:等效于.Finish() [英] Xamarin forms: The equivalent of .Finish()

问题描述

我有一个Xamarin Forms应用程序，在所有三个平台上都很好.该应用程序具有一个登录屏幕和一个用户已成功登录的其他页面.有没有办法与Xamrin for Android提供的Finish方法等效，该方法可以从导航堆栈中删除登录页面?如果用户持续按下后退"按钮，则他们最终将返回登录屏幕，这是不希望的.我曾尝试使用Navigation.PopAsync()，但似乎无法正常工作

I have a Xamarin Forms application which very well on all three platforms. The app has a login screen and other pages that are available one a user has successfully logged in. My question is: In Xamarin Forms; is there a way to have the equivalent of the Finish method that Xamrin for Android provides to remove the login page from the navigation stack? If a user keeps pressing the back button they eventually get back to the login screen which is undesirable. I have tried using Navigation.PopAsync () but seem not to work

推荐答案

Navigation.PopAsync和Navigation.RemovePage应该可以工作.

但是，如果您的页面也是MainPage，则无法将其删除.您可以使用以下代码将其更改为另一个页面:

BUT if your page is also a MainPage you can't remove it. You could change it to another page using this code:

App.Current.MainPage = new NavigationPage(new MyContentPage());
