Works for me. Not saying it doesn't work for you, but the problem isn't the
code.
Created a fresh Single View Application iOS project.
Replaced ViewController.m source with the code below.
Added a UITableView to the View Controller's View and hooked up the DataSource
to the View Controller.
Ran it in the Simulator.
Scrolled the table and could see all the dwarves.
