在UITableView中更改自定义Section视图的标题

Question

I have a UITableView with expand and collapse cells when I tap in the sections. Now I want to collapse the cells again when I tap in one of this cells and give the name of this cell to the section up there. I think that collapse is not a problem but I do not know how to change the name. I have done everything programmatically. Thank you

You can try like this:

1. add an observer in custom section view to update title. Because section view is reused in UITableView,need a parameter(such as: int sectionIndex) to definite witch section the section view belong to.

2. in tableView:viewForHeaderInSection: set sectionView.sectionIndex with indexPath.section

3. in tableView:didSelectRowAtIndexPath: post a notification with indexPath.section and title string
