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:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
CGFloat sectionHeaderHeight = ;
if (scrollView.contentOffset.y<=sectionHeaderHeight&&scrollView.contentOffset.y>=) {
scrollView.contentInset = UIEdgeInsetsMake(-scrollView.contentOffset.y, , , );
} else if (scrollView.contentOffset.y>=sectionHeaderHeight) {
scrollView.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, , , );
}
}
