i Know this question already been asked many times and I can put here many links for references like the one of them Persistant UDID alternate. And I fount this link for detailing about each identifier but every one telling us one solution to create from server and assign to user, as Facebook or Game Center doing.
- Is this possible that we create this from device side and that should be persistant always.
- Will apple reject if we use UDID in and doing some amend by some specific formula and send to server?
Looking for answer.
