iOS - Background Transfer Service for Auto Update data at fixed intervel

Question

I am developing an app of feeds, that fetches feed from server and display to users for read. It working fine when app starts but i want to load data in background when is suspended or terminate(in both case). As we can create IntentService in android and with a AlarmManager we can start that service after a every fixed hours (for ex. 3 hours), so whenever user comes to online he will be able to see latest data without waiting fetch for new feeds.

I have read Background Transfer Service & NSURLSession with silent remote notification but i could not understand how this will help me to achieve my objective.

When getting a remote notification how can i resume a NSURLSessionDataTask form AppDelegate.m file because we can't use delegate there.

Please help me to sort out this issue. Googling from last 2 days but didn't get success to achieve this.

You need to use Background Fetch instead of Background Transfer. Main purpose of Background Transfer is uploading or downloading files while when app in background state.
