ios - I want unique identifier string which detect iPhone device (just like UDID)? -


i want unique identifier string iphone devices instead of udid , mac.

1. udid , mac deprecated apple.
2. can use uuid change after reinstalling app or delete app.

i want unique value of device remain same after app reinstall or delete or upgrade ios version.

what can unique identifier using [[uidevice currentdevice] identifierforvendor]or other unique identifier generator. after should store value on keychain using keychainitemwrapper , use. once store value on key chain it'll not remove after delete , reinstall app.

here guide keychain access - link
