iOS UIScrollView在滚动时取消UIButton触摸 [英] iOS UIScrollView cancel UIButton touch on scroll

问题描述

我在UIScrollView中有一些UIButtons，但我不想延迟按钮触摸。但是，只要滚动视图检测到拖动/滚动，我想取消UIButton触摸并继续滚动UIScrollView。

I have some UIButtons within a UIScrollView, but I do not want to delay the button touches. However, as soon as the scroll view detects a drag/scroll, I want to cancel the UIButton touch and proceed with the scrolling of the UIScrollView.

我已经包含以下内容...

I have included the following...

_scrollView.delaysContentTouches = NO;

...但是（显然）拖动时按钮触摸不会取消。有没有人对如何实现这个功能有任何建议？

...but (obviously) the button touch does not cancel when dragged. Does anyone have any suggestions as to how I can implement this functionality?

推荐答案

你可以覆盖 UIScrollView 。

-(BOOL)touchesShouldCancelInContentView:(UIView *)view
{   
    return YES;
}

在你的UIButton中，你应该为不同的控制事件添加不同的方法。

And in your UIButton, you should add different method for different control events.

1. 显示 UIControlEventTouchDown 的高亮效果。


2. 的触发按钮> UIControlEventTouchUpInside | UIControlEventTouchUpOutside ;


3. 清除 UIControlEventTouchCancel 的高亮效果。

1. show highlight effect for UIControlEventTouchDown.
2. trigger button for UIControlEventTouchUpInside | UIControlEventTouchUpOutside;
3. clear highlight effect for UIControlEventTouchCancel.
