ios - 启动 App 时 Mvvmcross 颜色插件抛出错误

Question

我在我的 Core 和 iOS 项目中安装了 3.5.1 版的 Mvvmcross 颜色插件。当我启动应用程序时，应用程序崩溃并出现错误:

setup.Initialize() 失败；

    public override bool FinishedLaunching(UIApplication application, NSDictionary launchOptions)
    {
        _window = new UIWindow(UIScreen.MainScreen.Bounds);

        var setup = new Setup(this, _window);
        setup.Initialize();

        ApplyTheme();

        var startup = Mvx.Resolve<IMvxAppStart>();
        startup.Start();

        _window.MakeKeyAndVisible();

        return true;
    }

最后的 Mvx 调试跟踪是:

确保为 Cirrious.MvvmCross.Plugins.Color.PluginLoader 加载插件

知道哪里出了问题吗？

Answer 1

通过添加解决:

<assembly fullname="Cirrious.MvvmCross.Plugins.Color.Touch">
      <type fullname="*" />
</assembly>

到 Linker.xml
