How to get the section header view's title when selecting a Cell

I have an UITableView which has many sections, and each section has only 1 row.

What I want to do is that, when I click on a particular cell, the title of the header that corresponds to the cell should be changed.

I have set the section header using -tableView:viewForHeaderInSection:

How can I get the row header title inside the -tableView:didSelectRowAtIndexPath: method?

Swift 4:

let indexPath = IndexPath.init(row: 0, section: 0) // put here your row or section number..
let myHeaderView = tableView.headerView(forSection:indexPath.section)
let title = myHeaderView?.textLabel?.text

Swift solution:

let sectionHeaderView = table.headerViewForSection(indexPath.section)
let sectionTitle = sectionHeaderView?.textLabel?.text

I would suggest implementing both tableView:titleForHeaderInSection: and tableView:viewForHeaderInSection: (if both are implemented then iOS prefers viewForHeaderInSection:). Then have your implementation of tableView:viewForHeaderInSection: create its view with the label and populate it with the result of tableView:titleForHeaderInSection::

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
     UIView *yourHeaderView;
     UILabel *someLabel;

     // set up the view + label

     // if self doesn't implement UITableViewDelegate, you can use tableView.delegate
     someLabel.text = [self tableView:tableView titleForHeaderInSection:section];

     return yourHeaderView;
}

Now when you're responding to a row tap, it's very easy to get the corresponding title:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
     NSString *titleForHeader = [self tableView:tableView titleForHeaderInSection:indexPath.section];
}

You can get the header view for selected Index like :

UIView *headerView=[deviceTable headerViewForSection:indexPath.section];

Then get the child from the headerView by looping through.like 

for(UIView *view in headerView.subviews)
{
     if ([v isKindOfClass:[UILabel class]])
        {
            UILabel *label=(UILabel *)v;
            NSString *text=label.text;
        }
}

Edit: As Desdenova suggested :

    UITableViewHeaderFooterView *headerView=[deviceTable headerViewForSection:indexPath.section];
    NSString *title=headerView.textLabel.text;

Just use the datasource for the section header. So whatever NSArray you have that hold the string values for the 

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

just use that in the didSelectRowAtIndexPath:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
...
NSString *titleForHeader = [myHeaderTitleArray objectAtIndex:indexPath.section];
}

You can get the section index by using:

indexpath.section

With the section index, you can simply duplicate what you have in -(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section to get the section title.
