UITableView上添加按钮，按钮点击效果延迟的解决办法

在自定义的TableView的初始化方法做如下操作

- (instancetype)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        self.delaysContentTouches = NO;
        // iterate over all the UITableView's subviews
        for (id view in self.subviews)
        {
            // looking for a UITableViewWrapperView
            if ([NSStringFromClass([view class]) isEqualToString:@"UITableViewWrapperView"])
            {
                // this test is necessary for safety and because a "UITableViewWrapperView" is NOT a UIScrollView in iOS7
                if([view isKindOfClass:[UIScrollView class]])
                {
                    // turn OFF delaysContentTouches in the hidden subview
                    UIScrollView *scroll = (UIScrollView *) view;
                    scroll.delaysContentTouches = NO;
                }
                break;
            }
        }
        // ... 更多设置
    }
    return self;
}

重叠部分只响应按钮事件

- (BOOL)touchesShouldCancelInContentView:(UIView *)view
{
    if ([view isKindOfClass:[UIButton class]])
    {
        return YES;
    }
    return [super touchesShouldCancelInContentView:view];
}

结束，亲测搞定
