MvvmCross升級到8.x后，應用程式卡在SplashScreen

我將所有 MvvmCross 庫從 7.1.2 升級到 8.0.0。根據 mvvmcross 檔案中的“從 7 升級到 8”教程，我已經實作了必要的更改（覆寫 CreateLogProvider 和 CreateLogFactory 方法，并將 iocProvider 作為引數添加到 InitializeFirstChance、InitializeLastChance、InitializeNavigationService 和 CreateApp）：

public class Setup : MvxAndroidSetup
    {
        protected override IMvxAndroidViewPresenter CreateViewPresenter() => new HistoryViewPresenter(ViewAssemblies);

        protected override void InitializeFirstChance(IMvxIoCProvider iocProvider)
        {
            base.InitializeFirstChance(iocProvider);
            //Things are done here
        }

        protected override void InitializeLastChance(IMvxIoCProvider iocProvider)
        {
            base.InitializeLastChance(iocProvider);
            //Things are done here
        }

        protected override IMvxNavigationService InitializeNavigationService(IMvxIoCProvider iocProvider)
        {
            var loader = CreateViewModelLoader(iocProvider);
            Mvx.IoCProvider.RegisterSingleton<IMvxViewModelLoader>(loader);
            InitializeViewDispatcher(iocProvider);
            var dispatcher = CreateViewDispatcher();
            Mvx.IoCProvider.RegisterSingleton(dispatcher);
            var navigationService = new DeepNavigationService(null, loader, dispatcher, iocProvider);
            Mvx.IoCProvider.RegisterSingleton<IMvxNavigationService>(navigationService);
            return navigationService;
        }

       //Another things are done here

        protected override IMvxApplication CreateApp(IMvxIoCProvider iocProvider)
        {
            return new App();
        }

        protected override ILoggerProvider CreateLogProvider()
        {
            return new SerilogLoggerProvider();
        }

        protected override ILoggerFactory CreateLogFactory()
        {
            Serilog.Log.Logger = new LoggerConfiguration()
                .MinimumLevel.Debug()
                .CreateLogger();

            return new SerilogLoggerFactory();
        }
    }

我還在核心專案中創建了自定義應用程式啟動并設定了此類 RegisterCustomAppStart：

public class AppStart : MvxAppStart
    {
        public AppStart(IMvxApplication application, IMvxNavigationService navigationService) : base(application, navigationService) { }

        protected override Task NavigateToFirstViewModel(object hint = null)
        {
            return NavigationService.Navigate<StartupViewModel>();
        }
    }

public class App : MvxApplication
    {
        public override void Initialize()
        {
            //Services and Singletons are registered here.
            RegisterCustomAppStart<AppStart>();
        }
    }

這是問題 - 當我運行應用程式時，我的應用程式卡在 SplashScreen 中。有沒有人遇到過類似的問題？在以前的版本中，一切正常。我會很感激一些如何解決這個問題的建議

uj5u.com熱心網友回復：

我解決了這個問題 - 我改變了行：

var dispatcher = CreateViewDispatcher();

為了：

var dispatcher = Mvx.IoCProvider.Resolve<IMvxViewDispatcher>();

它有效。
