It is possible in two modes, which both keep your app alive. The first one is background audio, while you are playing music, your app will receive those notifications. The second one is background GPS tracking via Core Location.
If your app doesn’t perform one of these, its state is frozen in memory and you won’t receive any notification from the OS.
