Question

我是UITextFIeld的子类。该文本字段包含在UITableViewCell中。我想抓住双击手势，但不是单击。双击启用编辑（没有问题），我希望单击传递到单元格以选择行。

我通过在UITextfield上放置一个视图（doubleTapView）并将手势识别器附加到该视图来实现此功能。当我想开始编辑时，我隐藏了这个视图，TextView正常工作。

func addDoubleTapView() {
        doubleTapView = UIView(frame: bounds)
        addSubview(doubleTapView!)

        doubleTapRecognizer = UITapGestureRecognizer(target: self, action: #selector(doubleTap(_:)))
        doubleTapRecognizer?.numberOfTapsRequired = 2
        doubleTapRecognizer?.numberOfTouchesRequired = 1
        doubleTapView?.addGestureRecognizer(doubleTapRecognizer!)

        singleTapRecognizer = UITapGestureRecognizer(target: self, action: #selector(singleTap(_:)))
        singleTapRecognizer?.requireGestureRecognizerToFail(doubleTapRecognizer!)
        singleTapRecognizer?.numberOfTapsRequired = 1
        singleTapRecognizer?.numberOfTouchesRequired = 1
        singleTapRecognizer?.delegate = self
        doubleTapView?.addGestureRecognizer(singleTapRecognizer!)
    }

    func doubleTap(sender: UITapGestureRecognizer) {
        doubleTapView?.hidden = true
        doubleTapView?.userInteractionEnabled = false
        becomeFirstResponder()
    }

我想忽略单击但不知道如何做到这一点。我不能用

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool

因为当触摸进来时我还不知道它是单击还是双击的开始。如果有一种方法可以在响应者链上传递单击手势，我找不到它。
非常感谢任何帮助。崖
