There is a private method called -[UIApplication _getSpringBoardOrientation] which just calls another private method -[UIApplication activeInterfaceOrientation], which seems to give you the orientation of the current foreground app.

But as of my knowledge I do not think that it will capture orientation changes in background because UIDevice class not work like that. But you can do capture the last state of orientation when your application enters in the background using 

Objective-C
    -(void)applicationDidEnterBackground:(UIApplication *)application 

Swift
    func applicationDidEnterBackground(application: UIApplication)
