How to load uiview by selecting row from uitableview

My app is a view based app and i added following components on it

Five uibuttons

On selecting any button drop down in the form of uitableview

So it has Five tableviews as well.

My problem 开发者_如何学Gois how to load detail view by selecting any row ,i didn't added navcontrllr and this is code for .....but this not working nthing happens on selecting row.

- (void)tableView:(UITableView *)tv didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{   
    if([holidayData objectAtIndex:indexPath.row] == @"Sunday")
    {
        UIViewController *control = [[SundayController alloc] initWithNibName: @"MyViewController" bundle: nil];
        UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController: control];
        [self presentModalViewController: navControl animated: YES];
        [control release];
    }
    [tv deselectRowAtIndexPath:indexPath animated:YES];
}

I think

if ([holidayData objectAtIndex:indexPath.row] == @"Sunday")

compares the pointers and not the actual strings. Have you tried using

if ([[holidayData objectAtIndex:indexPath.row] isEqualToString:@"Sunday"])

?
