How to map generated device UUID on my mobile's UUID?

[#1]

Hi everybody I try to create push notifications on my ios device. I create a certificate, create notifier, user. And make the POST request on /devices with name device1.

The system generates me the following JSON

{
  "uuid": "a1979b7a-0c85-11e6-b64f-7dc941540709",
  "type": "devices",
  "name": "device1",
  "created": 1461767876263,
  "modified": 1461767876263,
  "metadata": {
    "path": "/devices/a1979b7a-0c85-11e6-b64f-7dc941540709",
    "collections": {
      "receipts": "/devices/a1979b7a-0c85-11e6-b64f-7dc941540709/receipts",
      "users": "/devices/a1979b7a-0c85-11e6-b64f-7dc941540709/users"
    }
  }
}

How can I map generated uuid on my mobile uuid? And how can I know my mobile's UUID?
