In my iOS application, the user has to register their unique device for full access of the app. The registration is done in the backend.
My Problem:
I need an `unique identifier` from the iPhone for the above purpose,
and which should be same even after the user uninstalled and reinstalled the app.
It seems like apple doesn't allow the developer to fetch:
- UUID
- UDID
- IMEI Number
- Device Token (If there is no push notification registration, and my app also have no push notifications)
- advertisingIdentifier (if there is no/proper Ad integration)
And the followings are not seems to be the same after reinstallation:
- MAC Address
- identifierForVendor
- My own UUID creation at first start up with
CFUUIDCreate.
I know this question may seems like duplicate. But I searched a lot in Stack,Google and so many blogs and sites. But couldn't able to find a proper solution. If someone knows this, please guide me. Thanking you in advance.
