Solution
Rather doing this thing ios 7 Introduce new method for
application:didReceiveRemoteNotification:fetchCompletionHandler:
Tells the app that a push notification arrived that indicates there is data to be fetched.
Implement this method if your app supports the remote-notification background mode. This method is intended as a means for apps to minimize the time that elapses between the user seeing a push notification and the app displaying the associated data. 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
