ios - Associate Facebook Account With Multiple Users in Parse -

in application utilize parse's services connect users facebook. when user tries connect facebook business relationship linked user in app, error given , user not allowed connect. since using anonymous users in app, particular problem if user deletes app , reinstalls, old business relationship still exists in database connected facebook account, have new anonymous user account, , cannot link new business relationship facebook.

what best way me prepare problem? if i'm not mistaken, there no way tell when user deletes application, can't delete old user database when app deleted. need way either log out old user , log in new user when new user tries connect facebook or allow multiple users linked same facebook account. or suppose merge new anonymous user business relationship old 1 linked facebook.

anyways, has had issue , found solution?
