Reusable TableView header views

For performance sake it is usual to reuse UITableView' cells. Is there a way to do the same thing with TableView header' views? I am talking about the ones that are returned with delegate's method:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section

I tried to do the following which doesn't seem to be working as expected:

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    static NSString *CellIdentifier = @"Header";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: CellIdentifier];
    if (cell == nil) {
        cell = [self getHeaderContentView: CellIdentifier];
    }
    return cell;
}

Is there a way to reuse header' views?
