Swift - WebView在加載時無法檢測到滑動

Question

在URL完成加載之前，在檢測到滑動之後，我的滑動未檢測到。任何想法如何檢測URL加載時滑動？

Answer 1

我才發現，我們只需要添加這兩條線：

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

完整的示例：

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)
