Question

I’m building an iPhone app, with the following structure:
I have the MainViewController which consists of 2 views (like split screen).
The first view of them, has a button. On tap, a UItableView (ResultTableViewController) appears in the second (of the above) view:

-(IBAction)buttonTapped:(id)sender {
  if ([(UIButton *)sender tag] == 0) {
      ResultsTableViewController *childViewController = [[ResultsTableViewController alloc] init];
      childViewController.tableView.delegate = self.results;        
      [self.results.view addSubview:childViewController.tableView];
    }
}

So I have a UItableView as a sub-view of a UIView.

The problem is that pushViewController() in didSelectRowAtIndexPath() of ResultTableViewController does not work (self.navigationController is nil).

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    DetailsViewController *detailView = [[DetailsViewController alloc] initWithNibName:@"DetailsViewController" bundle:[NSBundle mainBundle]];    
    [self.navigationController pushViewController:self.detailView animated:YES];
}

I have tried many of the solutions I found, but nothing works.

In my MainWindow.xib, I have only MainViewController added, is that the problem?

Thanks in advance!

Ok, I found it.
I had to declare my MainViewController as UINavigationControllerDelegate and create a secondary NavigationController in it. I push the viewController in my new navigationController and that’s it.
