I'm having a great deal of trouble doing something that should theoretically be pretty simple given how common it is in iOS 7: blur the screen as well as the status bar.
You can get a UIView representation of it with snapshotViewAfterScreenUpdates, but that won't convert to a UIImage. You can get a UIImage representation of the screen with drawViewHierarchyInRect but it doesn't include the status bar.
Is it at all possible to blur the status bar in iOS 7?
