我是一個MVVMCross的完整新手，但我試圖從github中獲取使用monodouch和Xamarin Studio與MVVMCross的最新二進制文件工作的依賴關係。國際奧委會不解決依賴關係 - MVVMCross
無法真正找到專用於Xamarin Studio + Monocross的教程，所以在配合一些教程後，我有一些微不足道的控件奇妙地工作。然後我嘗試着手繪製一些地圖特徵和一些DI。不幸的是，我收到錯誤，說依賴關係無法解決。我哪裏錯了？
// my view model
using System;
using Cirrious.MvvmCross.Plugins.Location;
using Cirrious.MvvmCross.ViewModels;
using Cirrious.CrossCore;
namespace mvxTest.Core
{
public class MapViewModel : MvxViewModel
{
private IMvxLocationWatcher _watcher;
public MapViewModel (IMvxLocationWatcher watcher)
{
// var resolved = Mvx.CanResolve<IMvxLocationWatcher>(); // returns false
_watcher.Start (new MvxLocationOptions(), OnSuccess, OnError);
}
}
}
// my view
using System;
using Cirrious.MvvmCross.Touch.Views;
using MonoTouch.UIKit;
using System.Drawing;
using Cirrious.MvvmCross.Binding.BindingContext;
using mvxTest.Core;
namespace mvxTest.Touch
{
// http://www.youtube.com/watch?v=MM9iQlx3quA
public class MapView : MvxViewController
{
public MapView()
{
}
public override void ViewDidLoad()
{
base.ViewDidLoad(); // <-- breaks here with complaints
var label = new UILabel (new RectangleF (0, 100, 100, 50));
label.BackgroundColor = UIColor.Blue;
Add (label);
var edit = new UITextView (new RectangleF (0, 200, 100, 50));
edit.BackgroundColor = UIColor.Green;
Add (edit);
var binding = this.CreateBindingSet<MapView, MapViewModel>();
binding.Bind (label).To ((v) => v.Lat);
binding.Bind (edit).To ((v) => v.Lng);
binding.Apply();
}
}
}
錯誤是混亂的，因爲它提到視圖模型的依賴性不解決，但是誤差在視圖中拋出時觸發事件viewDidLoad中。也許它的視圖模型被加載。無論如何，爲什麼不注入依賴關係 - 我懷疑插件需要在monotouch項目中註冊。

感謝您的建議斯圖爾特 - 看N31 + N8 N9的+位，我已經包括在觸摸項目LocationPluginBootstrap和共享相同的命名空間，它的偉大工程後 - THANKS !!：
