UITableView--区头跟随表一起滑动的效果

在tableView的滚动事件内,添加---

-(void)scrollViewDidScroll:(UIScrollView *)scrollView

{

    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);

    }

}
