【问题描述】：

在 URL 完成加载之前，在检测到滑动之后，未检测到我的滑动。知道如何在 URL 加载时检测滑动吗？

【问题讨论】：

你能展示你的代码吗？

【参考方案1】：

我刚刚发现，我们只需要添加这两行：

webView.scrollView.panGestureRecognizer.requireGestureRecognizerToFail(rightSwipeGesture)
webView.scrollView.panGestureRecognizer.requireGestureRecognizerToFail(leftSwipeGesture)

完整示例：

var rightSwipeGesture: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: #selector(self.handleSwipeGesture))
var leftSwipeGesture: UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: #selector(self.handleSwipeGesture))
rightSwipeGesture.direction = .Right
leftSwipeGesture.direction = .Left
self.view!.addGestureRecognizer(rightSwipeGesture)
self.view!.addGestureRecognizer(leftSwipeGesture)
webView.scrollView.panGestureRecognizer.requireGestureRecognizerToFail(rightSwipeGesture)
webView.scrollView.panGestureRecognizer.requireGestureRecognizerToFail(leftSwipeGesture)
