How to get the user information who are not in my roster list?
<p>I am working on group chat using robbiehanson/XMPPFramework. I have done sending invitation,accepting invitation and messaging in group chat. 
Here I want to show some information of user who sent message in group chat including his avatar. 
I can get the users information from <strong>XMPPUserCoreDataStorageObject</strong>. this case is applicable only if those users are present in my friend list. I need to get the users information who are not in my friend list. Is there any possible way to achieve this. Please suggest me </p>
