MLAnonymousUtils Class Reference

Inherits from NSObject
Declared in MLAnonymousUtils.h

Overview

Methods for working with Anonymously logged-in users. Anonymous users have some unique characteristics:

  • Anonymous users don't need a user name or password.
  • Once logged out, an anonymous user cannot be recovered.
  • When the current user is anonymous, the following methods can be used to switch to a different user or convert the anonymous user into a regular one:
    • signUp converts an anonymous user to a standard user with the given username and password. Data associated with the anonymous user is retained.
    • logIn switches users without converting the anonymous user. Data associated with the anonymous user will be lost.
    • Service logIn (e.g. Facebook, Twitter) will attempt to convert the anonymous user into a standard user by linking it to the service. If a user already exists that is linked to the service, it will instead switch to the existing user.
    • Service linking (e.g. Facebook, Twitter) will convert the anonymous user into a standard user by linking it to the service.
