tableView 让区头更随 cell 一起滚动

//去掉UItableview headerview黏性(sticky)
将一下方法粘过去改一个地方就够了
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
    if (scrollView == self.menuTableView)
    {
        CGFloat sectionHeaderHeight = 25; //sectionHeaderHeight你区头的高度
        if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {
            scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);
        } else if (scrollView.contentOffset.y>=sectionHeaderHeight) {
            scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);
        }
    }
}
