BackgroundColor of ViewControllers

• Expected behavior and actual behavior.
• Steps to reproduce the problem.

If building the demo2, the two ViewController display should have a gray background. However the background is plain white.

Also the delegate methods for the menuItem seems to have issues. For some reason they're not called. I'm working on it and will come back if I cant find why. Here a sample if you wish to have a look. It's mostly just a copy of the demo2 to play around the settings.

• Specifications like the version of the project, library, or Swift. I'm currently using xcode 8.1 and swift 3
