只去掉header的
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
if (scrollView == self.tableView)
{
CGFloat sectionHeaderHeight = 64; //你的header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);
}
}
header 和 footer 的
UITableView *tableview = (UITableView *)scrollView;
CGFloat sectionHeaderHeight = 64;//头
CGFloat sectionFooterHeight = 120;//脚
CGFloat offsetY = tableview.contentOffset.y;
if (offsetY >= 0 && offsetY <= sectionHeaderHeight)
{
tableview.contentInset = UIEdgeInsetsMake(-offsetY, 0, -sectionFooterHeight, 0);
}else if (offsetY >= sectionHeaderHeight && offsetY <= tableview.contentSize.height - tableview.frame.size.height - sectionFooterHeight)
{
tableview.contentInset = UIEdgeInsetsMake(-sectionHeaderHeight, 0, -sectionFooterHeight, 0);
}else if (offsetY >= tableview.contentSize.height - tableview.frame.size.height - sectionFooterHeight && offsetY <= tableview.contentSize.height - tableview.frame.size.height) {
tableview.contentInset = UIEdgeInsetsMake(-offsetY, 0, -(tableview.contentSize.height - tableview.frame.size.height - sectionFooterHeight), 0);
}
}
}
