去掉UITableView HeaderView或FooterView随tableView 移动的黏性(sticky)

控制器中实现以下方法即可:

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

 2 

 3     CGFloat sectionHeaderHeight = 40;

 4 

 5     if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=0) {

 6 

 7         scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, 0, 0, 0);

 8 

 9     } else if (scrollView.contentOffset.y>=sectionHeaderHeight) {

10 

11         scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, 0, 0);

12 

13     }
