XMPP retrieve public rooms on openfire server + iphone SDK - iphone

Question

I am developing a chat application in iphone using XMPPFramework. Everything is working great but stuck at the point. I want to retrieve a list of all public rooms but there is no method found in XMPPFramework. So can someone help me out to solve this issue?

Answer 1

Here is the code to get list of all room
NSString* server = #"chat.shakespeare.lit"; //or whatever the server address for muc is
XMPPJID *servrJID = [XMPPJID jidWithString:server];
XMPPIQ *iq = [XMPPIQ iqWithType:#"get" to:servJID];
[iq addAttributeWithName:#"from" stringValue:[xmppStream myJID].full];
NSXMLElement *query = [NSXMLElement elementWithName:#"query"];
[query addAttributeWithName:#"xmlns" stringValue:#"http://jabber.org/protocol/disco#items"];
[iq addChild:query];
[xmppStream sendElement:iq];
If you have code to get the room of specific user please share it

Answer 2

I use this code to query server directly, but I'm not sure that is the best way.
XMPPIQ *iq = [[XMPPIQ alloc] initWithType:#"get"];
NSString* conferenceHost = [NSString stringWithFormat:#"conference.%#", _xmppStream.hostName];
[iq addAttributeWithName:#"from" stringValue:conferenceHost];
[iq addAttributeWithName:#"to" stringValue:_host];
DDXMLElement *query = [DDXMLElement elementWithName:#"query" xmlns:#"http://jabber.org/protocol/disco#items"];
[iq addChild:query];
[_xmppStream sendElement:iq];
Hope this help someone.
By the way, if you adopt this solution, then you have to do some parse in delegate method:
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq {
}
I thing the best way is to parse method once the connection has started:
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {
/* parse */
}
Then you check
[[sender] from] domain]
if contains "conference." then you can think that sender is a room and finally you can add to NSMutableArray, for instance.
Also when a new room will be created, didReceivePresence will be called, so parser will add the new room.
So, you have:
NSMutableArray* rooms;
Your method will be:
-(NSMutableArray*)getRooms {
return _rooms;
}
