after a lot of searching and trying various solutions on this forum, i finally got something that works which i am posting below for the benefit of others that get stuck at this point.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"infoRegularSegue"])
    {


        FirstViewController *destViewController = segue.destinationViewController;
        destViewController.title = NSLocalizedString(@"Information", title of information view);

        //here is the solution to my problem
        UIBarButtonItem *backButton = [[UIBarButtonItem alloc]initWithTitle:NSLocalizedString(@"Return", returnbuttontitle) style:     UIBarButtonItemStyleBordered target:nil action:nil];
        self.navigationItem.backBarButtonItem = backButton;

    }
}
