Why use another UINavigationController for showing Tag list?

Hi Guys,

Maybe I’m missing something, but why use another UINavigationController to present the Tags UITableViewController? Why not present it modally using the existing one, that is the rootViewController of the application.

Best Regards,

I started to wonder about that as well when I saw your question.

So I tried it out. I realised that it is there so that the UITableViewController has a NavigationBar at the top with the “Done” and “+” (Add new tag) buttons. When I deleted the navigation controller and made the segue to go from the PhotoInfoViewController directly to TagsViewController the navigation bar disappeared.

It’s really cool, thanks for it…
