Instance Property

user

An identifier associated with the user’s Apple ID.

Declaration

@property(nonatomic, copy) NSString *user;

Discussion

Typically you leave this property set to nil the first time you authenticate a user. Otherwise, if you previously received an authorization containing an ASAuthorizationAppleIDCredential instance, set this property to the value from the credential’s user property.

The value is an arbitrary string that’s portable among apps from a single developer, but not between apps from different developers.
