首先我正在使用 mvvmcross version 3.0.13 . 当从继承自 MvxViewModel 的基类继承类时，不会从IoC调用Init方法 . 目前丑陋的解决方法是在构造函数中调用Init . 这可能是一个错误还是有其他模式可以使用？
在这两个类（基础和基础的子）中，它不会被调用 . 例如：
public class BaseViewModel : MvxViewModel
{
protected CDataImportService DataImportService { get; private set; }
protected CSettingService SettingService { get; private set; }
protected CDataService DataService { get; private set; }
protected CDocumentService DocumentService { get; private set; }
public BaseViewModel(IDataService objDataService, IDataImportService objDataImportService, IDocumentService objDocumentService, ISettingService objSettingService)
{
DataImportService = (CDataImportService)objDataImportService;
SettingService = (CSettingService)objSettingService;
DataService = (CDataService)objDataService;
DocumentService = (CDocumentService) objDocumentService;
}
public void Init()
{
Mvx.Trace("Init called in {0}", GetType().Name);
}
}
public class DocumentsViewModel : BaseViewModel
{
public MenuViewModel(IDataService objDataService, IDataImportService objDataImportService, IDocumentService objDocumentService, ISettingService objSettingService)
: base(objDataService, objDataImportService, objDocumentService, objSettingService)
{
}
}

它自己的IOC不会调用Constructor-Init-Reload-Start序列 .
IOC是一般的C＃服务，只调用构造函数部分 .
如果你想要调用整个序列，你可以通过IMvxViewModelLoader对象访问它 - 例如
Mvx.Resolve<IMvxViewModelLoader>().LoadViewModel(MvxViewModelRequest<MyViewModel>.GetDefaultRequest(), null);默认情况下，这将使用默认ViewModel定位器来创建视图模型实例 - https://github.com/MvvmCross/MvvmCross/blob/v3/Cirrious/Cirrious.MvvmCross/ViewModels/MvxDefaultViewModelLocator.cs
