Mobile Connected Client Plugin

The Connected Client Plugin is an Objective-C library written to accompany the Mobile App Bootstrap, but is also useful as a stand-alone class. It helps authenticate a user and keep them signed in using long-lived tokens. It can be used in the sample Mobile App Bootstrap or in another native mobile app.

As a plugin, it performs three authentication-related tasks:

1. Check if the user is signed in. This function should always be called before trying to load Tableau content.
   TableauOAuth.checkSignInStatus()
2. Manage long-lived tokens for a session. Long-lived tokens must be enabled on your server.
   TableauOAuth.requestOAuthTokens()
3. Sign out the user.
   TableauOAuth.signOut()

              Can they be refreshed?
                      |
              ___________________
             |                   |
            YES                  NO
      User is signed in.      User is NOT signed in.
                    

Long-lived tokens

The plugin completes four main tasks in order to handle long-lived tokens.

1. Get initial access/refresh tokens
2. Store in iOS Keychain
3. Refresh access token if expired
4. Revoke refresh and access token on sign out
