ios – “无法在MvvmCross .dialog中创建目标绑定”

因此,我正在玩iOS中的MvvmCross和Monotouch.Dialog,当我做一些非常微不足道的事情时,我遇到了一个绑定问题 – 事实上,在stuart的n 1视频中几乎完全逐字.

鉴于以下观点：

[Register("FirstView")]
public class FirstView : MvxDialogViewController
{
    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        var bindings = this.CreateInlineBindingTarget<Firstviewmodel>();

        Root = new RootElement("Example Root")
        {

            new Section("Search")
            {
                new EntryElement("SearchString","Search String").bind(bindings,vm => vm.SearchString)
            }
        };

    }
}

和这个viewmodel：

public class Firstviewmodel : Mvxviewmodel
{
    private String _searchString = "search String";
    public String SearchString
    {
        get
        {
            return _searchString;
        }
        set
        {
            _searchString = value; 
            RaisePropertyChanged(() => SearchString);
        }
    }

}

导航到此视图时,我从Mvx收到以下错误：

2013-08-22 14:44:51.766 TestApp[11581:c07] MvxBind:Error:  2.02 Empty binding target passed to MvxTargetBindingFactoryRegistry
[0:] MvxBind:Error:  2.02 Empty binding target passed to MvxTargetBindingFactoryRegistry
[0:] 
2013-08-22 14:44:51.869 TestApp[11581:c07] MvxBind:Warning:  2.10 Failed to create target binding for to 
[0:] MvxBind:Warning:  2.10 Failed to create target binding for to

我不确定绑定失败的原因.如果我在SearchString的“获取”中设置了一个断点,我确实看到它被击中了.但是,更改Entry元素的值不会触发“Set”.

有什么想法吗？
