IOS8 launcher screen with picture background

How can I create a startup screen with a background image in ios8 without breaking any of the guidelines outlined in Apple's documentation on the Create Startup Screen page?

The documentation says: https://developer.apple.com/library/ios/documentation/IDEs/Conceptual/AppDistributionGuide/ConfiguringYourApp/ConfiguringYourApp.html#//apple_ref/doc/uid/TP40012582-CH28-SW3 )

• Use only UIKit classes.
• Use a single root view, which is a UIView object or UIViewController. Don't make any connections to your code (don't add actions or outputs).
• Don't add UIWebView objects.
• Don't use any custom classes.
• Don't use runtime attributes.

I think I'm not the only one who might need a responsive launcher like this

but as i know, can't set the background from xib / storyboard.
