Question regarding a tutorial...

[mrshow555]

I'm following a tutorial on making a TableView using a SQlite database here:
iPhone SDK Tutorial: Reading data from a SQLite Database | dBlog.com.au

I started my project as a ViewBased application but I want to add a TableView so I made a new class with .xib and with the UITableViewController subclass boxes checked.

Now my question is, since I didn't start my project as a Navigation based proj I don't have the RootViewController files, so should I make one or whenever the tutorial references editing code in those files should I do it somewhere else, say in my MainView files?
