#####

The launch image (or default image) is displayed while your app launches. (If no default image is provided, then a black screen is displayed.)

To include a launch image in your app, add images of the appropriate size for the device. In iOS 8 and later, you can create a XIB or storyboard file instead of a static launch image. The launch XIB or storyboard is required to support iPhone 6 sized apps. See the Apple Documentation for more info.
