title: UITableView with static cells does not appear
body: <p>I have created a new Xcode project using Storyboards (tab view template). I added a couple of view controllers to my storyboard, and wanted to use a UITableView with static cells for one. I created it, but when I run in the simulator the cells don't appear. I haven't changed anything in the project except for this storyboard file. I am showing screenshots of the storyboard editor and the simulator running. The label shows up, so the view is loading correctly. I set the background color to gray so I can see the talbeview is loading. All cells are set to visible. I changed their style to Basic and edited the label, and added a disclosure indicator, that's all.</p>
