          get device id,i want to send it only at first time if it is same phone 
     }

Answer 1

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.
