Answer 1

You should use a background session configuration instead if a default session configuration. This ensures that your data transfer will continue in the background once the user has exited your app.

Of course, this is correct as long as the user has background fetching enabled for your app in the Settings app of the device.

Be sure to enable the Background fetch capability on your project settings:

Then implement the application:handleEventsForBackgroundURLSession:completionHandler: in your App Delegate to be informed when the data transfer ends and do whatever you need to do (UI update…) inside your app with the received/sent file. Don't forget to call the completionHandler to inform the system that you have ended your tasks. iOS then will take a screenshot of the active screen of your app and update the one in the iOS 7 multitasking screen.
