We can check Background App Refresh for whole device and for each particular application in iOS 7 manually from settings.
Is there any way to do it programmatically in iOS 7?

The short answer is no you can't check to see what every app's Background Refresh setting is due to application sandboxing. An application may how ever check to see if the user has modified the Background Refresh setting for itself.
