如何解决与webView及其子视图的手势冲突？

Question

我想在我的Web视图中添加双击手势，但不拦截自己的单击回调，我的子视图响应双击手势，但Web视图的单击回调将无效

{
    webMaskView = UIView()
    webVie w.addSubview(webMaskView)
    webMaskView.snp.makeConstraints { (make) in
        make.left.right.top.bottom.equalTo(webV)
    }
    let doubleTap = UITapGestureRecognizer(target: self, action: #selector(webViewTwoTaped(_ :)))
    doubleTap.delegate = self
    doubleTap.numberOfTapsRequired = 2
    webMaskView.addGestureRecognizer(doubleTap)
    webMaskView.isUserInteractionEnabled = true
    webMaskView.backgroundColor = UIColor.blue.withAlphaComponent(0.1)
}

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
    return true
}

override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
    return true
}

您无需为双击手势添加子视图，可以直接在Webview或WKWebView上添加双击手势。
