UIScrollview delaysContentTouches issue(UIScrollview delaysContentTouches 问题)

本文介绍了UIScrollview delaysContentTouches 问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有 UIScrollView 加载了 UIButtons 并且在 UIButton 动作上我突出显示了每个 的 UIImageUIButton.

I have UIScrollView loaded with UIButtons and on UIButton action I have highlighted UIImage of each UIButton.

如果我没有将 delaysContentTouches 设置为 NO，那么如果我不显示 UIButton 的突出显示 UIImageUIButton 的修饰非常快.在我将 delaysContentTouches 属性设置为 NO 之后，只显示 UIButton 突出显示的 UIImage.

If I don't set delaysContentTouches as NO then highlighted UIImage of UIButton will not shown if I touch up UIButton very fast. After I set delaysContentTouches property as NO then only UIButton highlighted UIImage is shown.

现在在 UIScrollView 将 delaysContentTouches 属性设置为 NO 之后.我无法通过拖动 UIButtons 来滚动我的 UIScrollView.现在我该如何解决这个问题.

Now after setting delaysContentTouches property as NO for UIScrollView. I can not scroll my UIScrollView by dragging on the UIButtons. Now how can I resolve this issue.

请给我一个建议.

提前致谢.

推荐答案

好的，我已经通过实现以下方法解决了:

OK I have resolved by implementing below method :

- (BOOL)touchesShouldCancelInContentView:(UIView *)view
{
    NSLog(@"touchesShouldCancelInContentView");

    if ([view isKindOfClass:[UIButton class]])
        return NO;
    else
        return YES;
}
