FreshMvvm PushNewNavigationServiceModal不工作

Question

当用户在方法FreshNavigationContainer中使用SuccessfulLogin中的loggedin时，我试图通过使用freshMvvm方法PushNewNavigationServiceModal将其从freshMvvm更改为PushNewNavigationServiceModal，但是没有发生任何事情。

    public void SuccessfulLogin()
    {
        App.IsLoggedIn = true;
        var masterDetailNav = new FreshMasterDetailNavigationContainer();
        masterDetailNav.Init("Menu");
        masterDetailNav.AddPage<ProfilePageModel>("Profile", null);
        CoreMethods.PushNewNavigationServiceModal(masterDetailNav);
    }

编辑：我只是注意到在使用这种方法之后，导航就不再起作用了。

Answer 1

您需要使用CoreMethods.SwitchOutRootNavigation

首先设置您的NavigationStacks

public class NavigationStacks
{
    public static string LoginNavigationStack = "LoginNavigationStack";
    public static string MainAppStack = "MainAppStack";
}

在您的App.xaml.cs中定义导航

FreshNavigationContainer loginMain;
FreshMasterDetailNavigationContainer masterDetailNav;

var loginPage = FreshPageModelResolver.ResolvePageModel<UserLoginPageModel>();
loginMain = new FreshNavigationContainer(loginPage, NavigationStacks.LoginNavigationStack);

var masterDetailNav = new FreshMasterDetailNavigationContainer(NavigationStacks.MainAppStack);
masterDetailNav.Init("Menu");
masterDetailNav.AddPage<ProfilePageModel>("Profile", null);

然后在你的登录ViewModel

public void SuccessfulLogin()
{
    App.IsLoggedIn = true;
    CoreMethods.SwitchOutRootNavigation(NavigationStacks.MainAppStack);
}
