Using gmail account from cache

[sagarpshah]

Since it uses SFSafariViewController, is it possible to use the earlier signed-in Gmail account from cache?

We have made an app and integrated GTMAppAuth library. We have a scenario, where user logs in for the first time via Gmail app and use the app. Now user deletes the app and re-install. Now when user tries to login again, it never uses the logged-in session and it always asks user to login again.

Is there any workaround where we may ask to use login from cache if available?
