You can store it locally on your phone. If the device token you get in didRegisterForRemoteNotificationsWithDeviceToken is equal to the locally stored one, you don't send it to your server. If you don't have a locally stored device token, or the locally stored token is different from the newly received one, send it to your server and update the locally stored token.

  • thankyou for help,still one doubt if user deleted the app after some days – siva Jul 16 '13 at 10:51
  • @siva If a user deletes the app, your server won't know about it immediately, but after you try to send a few push notifications to that device, the APNS service will detect the app is no longer installed on it, and the next time you run the Feedback service, the device token of that device will be returned (and you'll know you should remove that token from your DB). – Eran Jul 16 '13 at 21:42
  • thank you very much for your help,let me know how apple send that device token if user deletes – siva Jul 17 '13 at 04:46
