问题描述

我在 UIScrollView 中有一些 UIButton，但我不想延迟按钮的触摸.但是，一旦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.

我已包含以下内容...

I have included the following...

_scrollView.delaysContentTouches = NO;

...但是(显然)按钮触摸在拖动时不会取消.有人对我如何实现此功能有任何建议吗?

...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

你可以重写UIScrollView的这个方法.

You can override this method of UIScrollView.

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

在你的 UIButton 中，你应该为不同的控件事件添加不同的方法.

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

显示 UIControlEventTouchDown 的高亮效果.
UIControlEventTouchUpInside 的触发按钮 |UIControlEventTouchUpOutside;
清除UIControlEventTouchCancel的高亮效果.

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