问题描述
我有一个带标头的UITableView
.我目前遇到的问题是页眉不随表格滚动.当用户向上滚动表格视图时,我需要它滚动出屏幕(上方).表格视图滚动,但标题锁定在UIView
的顶部.
I have a UITableView
with a header. the problem I currently have is that the header doesn't scroll with the table. I need it to scroll off screen (above) when the user scrolls the table view up. the tableview scrolls but the header is locked at the top of the UIView
.
谢谢

推荐答案
在新方法中创建sectionHeader视图,然后添加到末尾:
create sectionHeader view in a new method and then add to the end:
self.tableView.tableHeaderView = sectionHeader;
