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