UIActionSheet missing background in iOS7

EDIT: This is intended behavior, but that was not obvious from the UI Transition Guide from Apple. I found a much better example here: http://iosandmacbuddy.wordpress.com/2013/07/30/ios-7/

In iOS7, the background has disappeared from my UIActionSheet. I know the UIActionSheetStyle constants are no longer used, but I wasn't using them before! In the UI Transition Guide (Page 45), the sample appears like this:

Mine, however appears without the grey background box, instead appearing as floating buttons with no background:

Am I misunderstanding and the grey box on the guide is the view behind the UIActionSheet? (and therefore my behavior is expected)

Solution

Honestly there is nothing wrong with that.

It looks perfectly fine to me.
