iOS开发~UITableView 在Plain下区头跟随移动

-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
    
    CGFloat sectionHeaderHeight = section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);
        }
    }
}
