Why not have the sample code just use the `[_UIBackdropView initWithStyle:]` method?

_UIBackdropViewSettings style numbers
Seems some numbers out there are not match with my _UIBackdropViewSettings object testing. We should specific iOS version for those numbers, maybe iOS 7.1 changed some numbers so they are different from iOS 7.0
