Question

我在表格单元格中有两个UIButton，在滚动时不方便按下。我怎么能阻止这个？

是否有我可以设置的属性或已发送事件，因此只有在用户释放按键时才按下按钮，而不是按下按钮后立即按下按钮？

我玩过不同的触摸事件（Touch Up Inside和Touch Down），似乎都没有解决这个问题。

Answer 1

您可以收听tableview的滚动委托回调并关闭正在滚动的按钮

- (void)scrollViewWillBeginDragging:(UIScrollView *)activeScrollView {

    //I assume the buttons are within your cells so you will have to enable them within your cells so you will probably have to handle this by sending a custom message to your cells or accessing them with properties.
    [yourButton setEnabled: NO];
}

并倾听

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
   // do the same to enable them back
   [yourButton setEnabled: YES];
}

在界面构建器中，将按钮的标记值更改为大于10的数字（或某个值）。子类UIScrollView并覆盖：

-(BOOL) touchesShouldCancelInContentView:(UIView *)view {

if(view.tag>10) {
    NSLog(@"should A");
    return YES;
} else return NO;

}

您的scrollView应将属性canCancelContentTouches设置为YES，将delaysContentTouches设置为NO
