How to scroll the header along with the UITableView?
提问by user2588945
I have a UITableViewwith 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.
我有UITableView一个标题。我目前遇到的问题是标题不随表格滚动。当用户向上滚动表格视图时，我需要它滚动屏幕（上方）。tableview 滚动但标题被锁定在UIView.
thanks
谢谢

That behavior is only common when the UITableViewStyleproperty of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.
只有当UITableViewStyle表的属性设置为时，这种行为才常见UITableViewStylePlain。如果您将其设置为UITableViewStyleGrouped，则标题将随单元格一起向上滚动。
This answer is taken from this question.
这个答案取自这个问题。
This solution works regardless of the number of headers.
无论标题的数量如何，此解决方案都有效。

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

if you have dynamic header view or single view select table style 
如果您有动态标题视图或单一视图选择表格样式

Changing the UITableViewStylefrom Plainto Groupedmake the section header to scroll with the other cells.
改变UITableViewStyle从Plain以Grouped使节头与其他细胞滚动。
回答by Rendel
If you write tableView.tableHeaderView = sectionHeaderyou will lose the actual table view header.
If you want to have table view header along with section headers you have to set UITableViewStyleproperty to UITableViewStyleGrouped.
Also if you want to calculate section header height automatically you can return UITableViewAutomaticDimensionin heightForHeaderInSectionmethod like this:
如果您写入，tableView.tableHeaderView = sectionHeader您将丢失实际的表视图标题。
如果您想要将表视图标题与节标题一起使用，您必须将UITableViewStyle属性设置为UITableViewStyleGrouped.
此外，如果您想自动计算节标题高度，您可以return UITableViewAutomaticDimension使用如下heightForHeaderInSection方法：
- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return UITableViewAutomaticDimension;
}

If you have a single header in the table then you can use tableHeaderViewas below:
如果表中有单个标题，则可以使用 tableHeaderView如下：
tableView.tableHeaderView = Header;
Or if you have multiple header in table than you need to use Group table instead of plain table.
或者，如果表中有多个标题，则需要使用组表而不是普通表。
