ios - Alternative For IdentifierForVendor in ios7 Above -

i noticed whenever reinstall app, identifierforvendor keeps on changing. there way me have same identifier device? thing is, need create sure identifier same because have backup scheme allows user re-download progress after deleting , reinstalling app. identifierforvendor isn't reliable value. looked @ advertisingidentifier it's no good. chance, know of string returned apple may utilize alternative? or there way generate same string device?

identifierforvendor reliable value, if app has been downloaded app store, won't alter if user uninstalls , reinstall.

edit: this no longer true, when app downloaded apple store identifierforvendor different if remove app , install again, changed on app update due apple bug it's fixed now, knows if happen again. identifierforvendor not reliable if want utilize it's recommended store it's value on keychain
