Swift - WebView 在加载时不检测滑动

Question

在 URL 完成加载之前，检测不到我的滑动，检测到滑动后。知道如何在 URL 加载时检测滑动吗？

Answer 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)
