I have iPhone 5c running latest iOS 8 update.
I know how to restrict certain apps from accessing internet when using cellular data.
I want to know if its possible to do same when Wi-Fi is turned on.
Question: Is there any way to restrict certain apps from using Wi-Fi on iOS 8?
Addition to my question above: I want to restrict messenger apps like WhatsApp and Line from accessing internet when my phone is using Wi-Fi connection? (I know its possible to do above when I am using cellular data).
