Camera Privacy Setting under iOS 8

Hello,

Is there any property within Titanium to check if the App has access to the camera or if it is blocked by the Privacy settings? I could´t find anything and the following properties have always the same values:

Ti.Media.isCameraSupported
Ti.Media.availableCameraMediaTypes
Ti.Media.availableCameras

Currently my camera shows a black screen the whole time.

Thanks Toni
