我在我的 ios 项目中使用了上面的代码，但它只是在输出中显示错误
未处理的异常

System.Collections.Generic.KeyNotFoundException: Presenter字典中没有配置类型MvxSidebarPresentationAttribute

Answer 1

您必须在 iOS 项目的 Setup.cs 文件中使用 MvxSidebarPresenter：

protected override IMvxIosViewPresenter CreatePresenter()
{
   return new MvxSidebarPresenter((MvxApplicationDelegate)ApplicationDelegate, Window);
}

你可以看到工作示例in the samples。
