couldn't use prepareForSegue to send some viewcontroller with navigation controller

to send some viewcontroller with navigation controller,

you can not send with DetailViewController2 *destViewController = segue.destinationViewController (X)

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"ShowDetails"]) {
        // [segue returns a UINavigationController and the controller you 
        // want is embedded in the navigation controller
        UINavigationController *navigationController = [segue destinationViewController];

        // We want the top view controller from the navigationController
        // and don't forget the cast
        DetailViewController2 *detailViewController = (DetailViewController2 *)navigationController.topViewController;



        // Removed redundant line as there was no need to create local variable for
        // one time use
        NSUInteger row = [[self.tableView indexPathForSelectedRow] row];

        // There was no need to have these two on on separate lines
        GameInfo *gameInfoObject = [GamesInfoArray objectAtIndex:row];

        // To add a fail safe you could wrap this in respondsToSelector
        // just in the event that the topViewController isn't a DetailViewController2 
        if ([detailViewController respondsToSelector:@selector(setDetailArray:)]) {
            // Note the lowercase for detailArray see comments above this property.
            detailViewController.detailArray = @[gameInfoObject.HomeTeam, gameInfoObject.AwayTeam];  
        }
    }
}
