ios - 如何使用 xmpp ios 加入群组并获取现有群组的列表

Question

我正在使用xmpp jabber客户端实现群聊。我使用下面的代码成功创建了组。

 -(void) CreateRoom { 
XMPPRoomMemoryStorage *roomStorage = [[XMPPRoomMemoryStorage alloc] init]; 
XMPPJID *roomJID = [XMPPJID jidWithString:[NSString    stringWithFormat:@"NewGroup@conference.%@",JABBER_DOMAIN_NAME]];
XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomStorage jid:roomJID dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:appDelegate.xmppStream];
[xmppRoom addDelegate:self
    delegateQueue:dispatch_get_main_queue()];

[xmppRoom joinRoomUsingNickname:appDelegate.xmppStream.myJID.user
                    history:nil
                   password:nil];
}
- (void)xmppRoomDidCreate:(XMPPRoom *)sender
{
 NSLog(@"xmppRoomDidCreate");
}
- (void)xmppRoomDidJoin:(XMPPRoom *)sender
{
NSLog(@"xmppRoomDidJoin");
[sender fetchConfigurationForm];

[sender inviteUser:[XMPPJID jidWithString:@"Test1"] withMessage:@"Greetings!"];
[sender inviteUser:[XMPPJID jidWithString:@"Test2"] withMessage:@"Greetings!"];
}

所以请建议我一种方法，我如何加入用户获取现有组的列表以进一步实现。 谢谢，

您可以使用此方式获取 MUC 服务器上的组列表 protocol: http://jabber.org/protocol/disco#items :

- (void) getListOfGroups
{
    XMPPJID *servrJID = [XMPPJID jidWithString:CONFERENCE_ROOM_SERVER];
    XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:servrJID];
    [iq addAttributeWithName:@"from" stringValue:[[self xmppStream] myJID].full];
    NSXMLElement *query = [NSXMLElement elementWithName:@"query"];
    [query addAttributeWithName:@"xmlns" stringValue:@"http://jabber.org/protocol/disco#items"];
    [iq addChild:query];
    [[self xmppStream] sendElement:iq];

}
