I think you have to show this link : https://xmpp.org/extensions/xep-0048.html . Here you can find the solution of Auto join and room storage.

There is No way for , reEnter to your rooms Automatically. you should make a loop in your group list ( rooms ) and Enter to each of them. i recommend to do it by operationQueue.
