How do I get a disclosure indicator in my tableview header section?

Question

我正在自定义Tableview中的标题，并且想在标题中添加一个Discloure指示器（箭头），这是可能的吗？

Answer 1

If you already customized your header view you can simply add a custom UIButton with an image of a discloure indicator add add it as a subview to your header view.

If you need further help you are most welcome.

EDIT Jonathan is right, the UIButton has a UIButtonTypeDetailDisclosure so there is no need for a custom image.

Answer 2

You can fetch the header view using

- (void)tableView:(UITableView *)tableView willDisplayHeaderView:(UIView *)view forSection:(NSInteger)section

Then fetch the actual header view

UITableViewHeaderFooterView *header = (UITableViewHeaderFooterView *)view;

Create a button with detail disclosure

UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

Then set the frame of this button and add it to the header view
