you can use pushkit type voip push notification achieve this.

even if app force stopped it'll launched on arrival of pushkit voip pushnotifcation.

here of advantages

  • the device woken when voip pushes occur, saving energy. unlike standard push notifications, user must respond before app can perform action, voip pushes go straight app processing.

  • voip pushes considered high-priority notifications , delivered without delay.

  • voip pushes can include more data provided standard push notifications.

  • your app automatically relaunched if it’s not running when voip push received.

  • your app given runtime process push, if app operating in background.

  • this type of notification can carry upto 4096 bytes
