Xamarin.ios MvvmCross-binding iOS手势

我正在寻找一种方法，如何将ios手势（如UILongPressGestureRecognitor）绑定到MvvmCross中的ICommand或MvxCommand，谢谢

PS：我找到了一个例子，但我不知道怎么做。

根据您找到的例子和当前的MVVM跨源代码，我做了以下操作

public static class MvxBehaviourExtensions
{
    public static MvxLongPressGestureRecognizerBehaviour LongPress(this UIView view)
    {
        var toReturn = new MvxLongPressGestureRecognizerBehaviour(view);
        return toReturn;
    }
}

及

你不明白这个例子的哪一点？如果用

LongPress

替换

Tap

，那么什么不起作用？是否存在编译错误？或者运行时异常？我添加了类LongPressBehavior和BehaviorExtensions，但是当我创建label.LongPress（）时；它不认识它。

public class MvxLongPressGestureRecognizerBehaviour
    : MvxGestureRecognizerBehavior<UILongPressGestureRecognizer>
{
    protected override void HandleGesture(UILongPressGestureRecognizer gesture)
    {
        // Long press recognizer fires continuously. This will ensure we fire
        // the command only once. Fire as soon as gesture is recognized as
        // a long press.
        if (gesture.State == UIGestureRecognizerState.Began)
        {
            FireCommand();
        }
    }

    public MvxLongPressGestureRecognizerBehaviour(UIView target)
    {
        var lp = new UILongPressGestureRecognizer(HandleGesture);

        AddGestureRecognizer(target, lp);
    }
}

set.Bind(this.LongPress()).For(lp => lp.Command).To(c => c.DoTheStuffCommand);
