Here you just use the RWTScaryBugDoc initializer to create four sample bugs, passing in the title, rating, and images for each. You add them all to a NSMutableArray, and set them on your table view.
Speaking of which, you can get a pointer to the RootViewController since you know it’s the first view controller in the navigation controller’s stack. There are other ways you could have gotten a pointer as well, but this is one easy way.
