In this lesson, I wanted to go over a very simple yet confusing issue that arises when you try to use a UITableViewController and add custom subviews inside of it. If you're trying to add the simple close button that we have in the top right corner into our AppFullscreenController you'll quickly notice that it doesn't appear correctly. Instead, what you should do is use a UIViewController as your super class and manually add in your subviews that you want. I'll quickly show you the modifications that we'll perform to have everything in working order. Enjoy.
