在UIWebView中滑动手势识别 [英] Swipe Gesture Recognition Inside UIWebView

问题描述

我已经阅读了很多关于此的问题，但它们似乎都没有实现我想要的......所以我可以说我有一个任意的 UIWebView 一个 UIViewController 。 UIViewController 有一个 SwipeGestureRecognizer ，工作正常。它甚至可以在 UIWebView 中工作 - 只要没有滚动条。 （在我加载页面之前，或者即使我加载的页面适合我的 UIWebView 的大小）。但是，如果我加载一个需要向左或向右水平滚动的网页，那么在我的视图的 UIWebView 部分内，我无法识别任何滑动手势。每次单击/拖动/滑动都会触发滚动操作。有没有办法区分滑动和只是用手指滚动（不是提起它而是拖动滚动）。

I have read a bunch of questions on this but none of them seem to achieve what I am looking for... So lets say I have an arbitrary UIWebView inside of a UIViewController. The UIViewController has a SwipeGestureRecognizer that works fine. It even works within the UIWebView-- whenever there is no scrollbar. (Before I load a page or even if I load a page that can fit appropriately within the size of my UIWebView). However, if I load a webpage that requires horizontal scrolling left or right, then inside the UIWebView part of my view, I cannot get any swipe gestures to be recognized. Every click/drag/swipe just triggers the scroll action. Is there a way to differentiate between a "swipe" and just scrolling with your finger (not lifting it but rather dragging to scroll).

推荐答案

你必须继承UIWebView并覆盖手势识别器调用。

You will have to subclass UIWebView and override the gesture recogniser calls.
