不允许UIScrollView捕获子视图 [英] Disallow UIScrollView from catching subviews touches

问题描述

我有一个 UIScrollView 覆盖了自定义 UIView ，它绝对需要监听所有的触摸事件

I've got a UIScrollView covered with a custom UIView which desperatly needs to listen to all the touch events that happen inside of him.

首先，我得到的是 touchesBegan：和 touchesCancelled：事件。否 touchesMoved：，否 touchesEnded：。事实上，所有拖动手势都被上面的 UIScrollView 取消了。这是通过以下设置解决的：

At first, all I was getting was touchesBegan: and touchesCancelled: events. No touchesMoved:, no touchesEnded:. In fact, all the dragging gestures where being canceled by the above UIScrollView. This was solved by the following setting:

_scrollView.canCancelContentTouches = NO;

现在，行为会根据第一次触摸UIView的时间长度而改变。如果它很短，那么相对拖动被管理，因为它是 UIScrollView 的滚动。如果它很长，那么我会在我的UIView中获得 touchesMoved：事件。

Now, the behaviour changes depending on the "length in time" of the first touch on the UIView. If it's short, then the relative dragging is managed as it was a scroll for the UIScrollView. If it's long, then I'm getting the touchesMoved: events inside my UIView.

我想要的是总是在我的UIView中接收 touchesMoved：。

What I want is to always receive touchesMoved: inside my UIView. How can I make it?

推荐答案

您是否已尝试修改 delaysContentTouches 属性 UIScrollView ？我有一个类似的问题，解决了。

Have you tried modifying the delaysContentTouches property of your UIScrollView? I had a similar issue, solved it.
