List of chat room members

Question

How can I retrieve the list of members of a chat room in using XMPP framework?

I tried using:

 - (void)xmppRoom:(XMPPRoom *)sender didFetchMembersList:(NSArray *)items 

But it returns an empty array

Answer 1

This question is old but I recently encountered this exact issue (xmppRoom:didFetchMembersList: is passed an empty array). In my case the problem was that when users got invited to the room they would have a role of "participant" and an affiliation of "none". The fetchMembersList method in XMPPRoom looks for items with an affiliation of "member".

You can change the affiliation like so:

[xmppRoom editRoomPrivileges:@[[XMPPRoom itemWithAffiliation:@"member" jid:userJID]]];

For details on roles and affiliations, see XEP-0045.

Answer 2

use this method when you invite users.

-[xmppRoom editRoomPrivileges:@[[XMPPRoom itemWithAffiliation:@"member" jid:userJID]]];

After you create xmpproom object and call following delegate method

-(void)xmppRoomDidJoin:(XMPPRoom *)sender{
    [sender fetchMembersList];
}


- (void)xmppRoom:(XMPPRoom *)sender didFetchMembersList:(NSArray *)items{
    NSLog(@"print user list=====%@",items);
    for (NSXMLElement *xmlItem in items) {
        NSString *jid = [[xmlItem attributeForName:@"jid"]stringValue];
          NSLog(@"print user jid=====%@",jid);
    }
}
