Question

我有一个MvxBaseBindableCollectionViewCell，它加载一个包含自定义按钮的xib。我希望能够将此自定义按钮传递给要绑定的ViewModel。这可能吗？

我正在努力实现像MyButton.ViewModel = ViewModel.ChildViewModel之类的东西，并将ViewModel.ChildViewModel.Name显示为按钮标题。

如果你想自定义绑定一个单元格，那么http://slodge.blogspot.co.uk/2013/01/uitableviewcell-using-xib-editor.html

就有了这方面的教程

如果要在该视图中创建完全可绑定的UIButton，则可以使用以下某些继承来执行此操作：

[Register("MyButton")]
public class MyButton
    : UIButton
      , IMvxServiceConsumer
{
    private IList<IMvxUpdateableBinding> _bindings;

    private const string BindingText = "SpecialTitle Customer.Name";

    public MyButton()
    {
    }

    public MyButton(IntPtr handle)
        : base(handle)
    {
    }

    protected override void Dispose(bool disposing)
    {
        if (disposing)
        {
            foreach (var binding in _bindings)
            {
                binding.Dispose();
            }
            _bindings.Clear();
        }
        base.Dispose(disposing);
    }

    private object _dc;

    public object DataContext
    {
        get { return _dc; }
        set
        {
            _dc = value;
            if (_bindings == null)
            {
                var binder = this.GetService<IMvxBinder>();
                _bindings = binder.Bind(_dc, this, BindingText).ToList();
            }
            else
            {
                foreach (var binding in _bindings)
                {
                    binding.DataContext = _dc;
                }
            }
        }
    }

    public string SpecialTitle
    {
        get { return this.GetTitle(UIControlState.Normal); }
        set { this.SetTitle(value, UIControlState.Normal); }
    }
}
