With iOS7 you have a new method called application:didReceiveRemoteNotification:fetchCompletionHandler: which you probably could use for your task. From Apple's Docs:

Implement this method if your app supports the remote-notification background mode. ... When a push notification arrives, the system displays the notification to the user and launches the app in the background (if needed) so that it can call this method. Use this method to download any data related to the push notification. When your method is done, call the block in the handler parameter.

Unlike the application:didReceiveRemoteNotification: method, which is called only when your app is running, the system calls this method regardless of the state of your app.
