Question

I have a ViewBased App. I added a UITableView on one of the UIViewControllers. It shows the data and I implemented all the delegate methods etc. My problem is when I want to show the detailView it just doesn’t happen. My code:

   - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
    {
       DetailViewController *detailViewController =[[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];

       NSLog(@"DidSelectRowAtIndexPath");

        // Pass the selected object to the new view controller.
        [self.navigationController pushViewController:detailViewController animated:YES];
        [detailViewController release];
    }

I see that I need a navigationController but I don’t have one and I was unsucessful trying to add one programatically. I don’t have one in my appDelegate either, so my question is do I need to add one to show the detail view? If yes, please give me a code sample how to do that.
If not, what other way is there?

I am new to iOS so I am a bit lost here.
Please help!

To add a navigation controller programmatically just for this detail view, you need to something like this:

UINavigationController * controller = [[UINavigationController alloc] initWithRootViewController:detailViewController];

[[detailViewController] release];

[self presentModalViewController: controller animated: YES];

If you want to use pushViewController, you need to already have a navigation controller surrounding the view you’re starting with.
