怎么让tableview的section的headerView随着cell一起滑动

- (void)scrollViewDidScroll:(UIScrollView *)scrollView {

    if (scrollView == self.myTableView)

    {

        CGFloat sectionHeaderHeight = [AdaptationKit getVerticalSpace:70];

        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);

        }

    }

}
