WinRT - 如何从导航历史记录中忽略或删除页面

问题描述

我的 WinRT metro (c# - xaml) 应用程序有以下情况:

I have following situation in my WinRT metro (c# - xaml) application :

用户启动应用程序但他或她没有登录.在菜单栏中，我有将他们导航到购物车的按钮.值得一提的是，无论登录/退出状态如何，他们都可以点击它.

User launch the application and he or she is not logged in. In the menu bar I have button which navigates them to Shopping cart. It's important to mention that they can click on it regardless of logged in/out status.

所以我有这个:

Home Page - > Login Page - > Shopping Cart

一切都很好，但是当我尝试在我的 购物车 页面上按 BACK 按钮时，我被导航回 Login 页面，这是有道理的，因为页面是在我的导航历史中.但我不希望这样，我想将用户返回到主页并跳过登录页面.

And everything works great, but when I try press BACK button on my Shopping Cart page I'm navigated back to Login Page, which make sense, because page is in my navigation history. But I don't want that, I want to return user to Home Page and skip login page.

我的问题是如何做到这一点，以及如何在 WinRT 上操作框架导航堆栈.我尝试了两次返回，但没有成功.

My question is how to do that, and how to manipulate Frame Navigation Stack on WinRT. I tried with going Back twice, but with no luck.

顺便说一句，我的页面是LayoutAwarePage"页面，我正在使用与此类似的 NavigationServicehttp://dotnetbyexample.blogspot.com/2012/06/navigationservice-for-winrt.html.

Btw, my page is "LayoutAwarePage" page and I'm using NavigationService similar to this http://dotnetbyexample.blogspot.com/2012/06/navigationservice-for-winrt.html.

推荐答案

你可以用不同的方式来处理它.您可以使后退按钮多次导航，直到它到达主页或跳过登录页面.您还可以使登录页面显示在导航 Frame 之外 - 在弹出窗口或应用程序的不同层中.

You can approach it in different ways. You can make it so the back button navigates back multiple times until it reaches the home page or skips through the log in page. You could also make the log in page something that shows up outside of the navigation Frame - either on a popup or in a different layer in the application.

*更新

在 8.1 中，平台引入了 Frame 上的 "noreferrer">BackStack 和 ForwardStack 属性，您可以对其进行操作.

In 8.1 the platform introduced the BackStack and ForwardStack properties on the Frame which you can manipulate.
