xamarin - FreshMvvm PushNewNavigationServiceModal不起作用

Question

当用户通过使用freshMvvm方法FreshNavigationContainer在方法FreshMasterDetailNavigationContainer中登录时，我试图将SuccessfulLogin更改为PushNewNavigationServiceModal，但没有任何 react 。

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

编辑:
我只是注意到使用此方法后，导航不再起作用。

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);

然后在您的登录ViewModel中

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