iOS checking if background services are enabled

Hi, I am using SK 3.5.1GA, Appc 4.0 - testing on an iOS 7 device and iOS8 emulator

Is there a way to check if background services are enabled for my app by the user in IOS? I have looked through all of the documentation and can't find anything taht allows me to check. Even calling Titanium.App.iOS.registerBackgroundService() with background services disabled for the app will return a background service object and run it (although not for very long).

I have seen other apps (e.g. Google Maps) ask for the setting to be enabled so it seems it can be detected somehow.
