in plainsytle tableview , we set headerViews for each section by delegate method
-(UIView*)tableView:(UITableView*)tableView viewForHeaderInSection:(NSInteger)section
so,when i scrolling up tableview , the first section's headerView is always showing on the top of tableview before the section totally disappear on the tableview , then the second section's headerView will show on the top of tableview instead . so my question is how can i make headerView scroll accompanying with uitableViewCell , just like group style tableview ?
