Currently i am making chat application.

I will implement Group chat exit same like Whats app.

For example, I am group owner and after some time i will leave from Group.After i leaving from group any one member of the Group assign as a Group owner.

For that i applied following code :

1st fetch all members in the groupchat and then all members left groupchat manually but it also not working.

NSXMLElement *query = [NSXMLElement elementWithName:@"query" xmlns:@"http://jabber.org/protocol/muc#admin"];

NSXMLElement *item = [NSXMLElement elementWithName:@"item"];

[item addAttributeWithName:@"affiliation" stringValue:@"member"];

[item addAttributeWithName:@"jid" stringValue:@"jid to remove"];

[query addChild:item];

XMPPIQ *RemoveUser = [[XMPPIQ alloc] initWithType:@"set" to:[XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",dialuser2,kSIPDomain]] elementID:@"some random id" child:query];

[SharedAppDelegate.xmppStream sendElement:RemoveUser];

so any one have code or related information then please help me.

Thank you.

I think you need to set the affiliation to owner but not member.

As Xmpp Owner Usecases, Xmpp Admin Usecases describe (Notice the values of affiliation):

  • To promote a user as owner:

<iq from='crone1@shakespeare.lit/desktop' id='owner1' to='coven@chat.shakespeare.lit' type='set'> <query xmlns='http://jabber.org/protocol/muc#admin'> <item affiliation='owner' jid='hecate@shakespeare.lit'> <reason>A worthy witch indeed!</reason> </item> </query> </iq>

  • To revoke a membership

<iq from='crone1@shakespeare.lit/desktop' id='member2' to='coven@chat.shakespeare.lit' type='set'> <query xmlns='http://jabber.org/protocol/muc#admin'> <item affiliation='none' jid='hag66@shakespeare.lit'> <reason>Not so worthy after all!</reason> </item> </query> </iq>

  • To ban a user

<iq from='kinghenryv@shakespeare.lit/throne' id='ban1' to='southampton@chat.shakespeare.lit' type='set'> <query xmlns='http://jabber.org/protocol/muc#admin'> <item affiliation='outcast' jid='earlofcambridge@shakespeare.lit'> <reason>Treason</reason> </item> </query> </iq>
