I am making a simple navigation based application that drills down one level and show a new xib file each time. When I drill down one level my screen shows up blank. I still have the navigation controller at the top with a back button but my view dosent load.

Here is my code

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    circle_area *subViewOneController = [[circle_area alloc] init];
    UIViewController *tvc = subViewOneController;
    if (indexPath.row == 0 && indexPath.section == 0) {
        [[self navigationController] pushViewController:tvc animated:YES];
    }
}

like I said this returns a blank screen.
