Uniquely identifying an iOS user

Question

I\'d like to create a user account on the server for new users of an app, but I\'d also like to not ask the user to type in anything. Ideally, I\'d like this to be automatic

Answer 1

An alternative to Erik's suggestion is a third-party library called OpenUDID. You can generate a unique identifier on a per-device basis, and it's dead simple:

#include "OpenUDID.h"
NSString* openUDID = [OpenUDID value];
