Listing out Books With all our custom models now defined, we're ready to move onto listing out our books in a UITableViewController. First, we'll need to use a UINavigationController as the root of our application so we can get a nice UINavigationBar to show at the top of our views. In addition, I'll show you how to ignore the storyboard as I believe it is easier to learn iOS programming this way. Finally, we set our list...
