将触摸从 UIScrollView 传递到 superview (UIButton)

Pass touch from UIScrollView to superview (UIButton)(将触摸从 UIScrollView 传递到 superview (UIButton))

问题描述

可能是重复的，但我找不到我今晚搜索问题的确切答案...

Possibly a duplicate, but I couldn't find an exact answer to my problem searching SO tonight...

我有一个 UIButton，其中包含一个 UIScrollView，所以该按钮是超级视图.

I have a UIButton which contains a UIScrollView, so the button is the superview.

我想要做的就是将单击事件从 UIScrollView 子视图传递到 UIButton 超级视图，并拥有 UIButton 句柄就像用户直接点击按钮一样.

All I want to do is pass a single-tap event from the UIScrollView subview to the UIButton superview, and have the UIButton handle it as it would if the user tapped the button directly.

将滚动视图的 userInteractionEnabled 属性设置为 NO 对我不起作用，因为用户可以滚动内容.这样做会破坏滚动视图的目的.

Setting the scroll view's userInteractionEnabled property to NO won't work for me because there is content the user can scroll. Doing so would defeat the purpose of the scroll view.

这可能吗?谢谢！

推荐答案

就像火心鸟说的那样，你的观点肯定不常见.

Like huoxinbird said, it's definitely not common to lay your views like that.

如果您对此非常坚持，您可以使用 UITapGestureRecognizer 并让它调用按钮的目标和选择器.

In the case where you are solidly adamant about this, you could use UITapGestureRecognizer and have it call the button's target and selector.

如果您想包括按钮突出显示等，那么您可能必须继承 UITapGestureRecognizer 并将 touchesEnded 转发给按钮.

If you wanted to include the button highlight and such, then you may have to subclass UITapGestureRecognizer and forward the touchesEnded to the button.
