我正在开发iOS聊天客户端，有人能帮我处理多用户聊天吗？

我已经实现了Robbie Hanson的XMPPFramework。

有人能告诉我如何使用这个框架获得群组列表并在服务器上创建群组吗？

提前感谢。

大家好，感谢你们和Stack Overflow的帮助，我已经成功创建了一个群组，并且可以使用核心数据和内存存储发送邀请给其他人。问题是当我创建第二个群组时，它会从核心数据存储中删除第一个群组的数据。另外，我们如何自动加入其他用户？ - Mangesh

这里是 Swift 版本：

func joinRoom(with jidString: String, delegate: XMPPRoomDelegate) -> XMPPRoom {

    let roomJID = XMPPJID(string: jidString)
    let roomStorage = XMPPRoomCoreDataStorage.sharedInstance()

    let room = XMPPRoom(roomStorage: roomStorage, jid: roomJID, dispatchQueue: DispatchQueue.main)!

        room.activate(xmppStream)

        room.addDelegate(delegate, delegateQueue: DispatchQueue.main)

        // If the room is not existing, server will create one.
        room.join(usingNickname: xmppStream.myJID.user, history: nil)

        return room
    }

    // MUCRoomDelegate
    public func xmppRoomDidCreate(_ sender: XMPPRoom!) {
        print("xmppRoomDidCreate")

        // I prefer configure right after created
        sender.fetchConfigurationForm()
    }

    public func xmppRoomDidJoin(_ sender: XMPPRoom!) {
        print("xmppRoomDidJoin")
    }

    public func xmppRoom(_ sender: XMPPRoom!, didFetchConfigurationForm configForm: DDXMLElement!) {
        print("didFetchConfigurationForm")

        let newForm = configForm.copy() as! DDXMLElement

        for field in newForm.elements(forName: "field") {

            if let _var = field.attributeStringValue(forName: "var") {

                switch _var {
                case "muc#roomconfig_persistentroom":
                    field.remove(forName: "value")
                    field.addChild(DDXMLElement(name: "value", numberValue: 1))

                case "muc#roomconfig_membersonly":
                    field.remove(forName: "value")
                    field.addChild(DDXMLElement(name: "value", numberValue: 1))

                // other configures
                default:
                    break
                }

            }

        }

        sender.configureRoom(usingOptions: newForm)
    }

    public func xmppRoom(_ sender: XMPPRoom!, didConfigure iqResult: XMPPIQ!) {
        print("didConfigure")
    }

获取房间列表：

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];

检查委托方法中的响应：

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{
    DDLogVerbose(@"%@", [iq description]);
    return NO;
}

加入或创建房间

XMPPRoomMemoryStorage * _roomMemory = [[XMPPRoomMemoryStorage alloc]init];
NSString* roomID = @"roomExample@chat.shakespeare.lit";
XMPPJID * roomJID = [XMPPJID jidWithString:roomID];
XMPPRoom* xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:_roomMemory
                                             jid:roomJID
                                   dispatchQueue:dispatch_get_main_queue()];
[xmppRoom activate:self.xmppStream];
[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoom joinRoomUsingNickname:@"myNickname"
                        history:nil
                       password:nil];

检查 XMPPRoom 代理方法中的响应：

- (void)xmppRoomDidCreate:(XMPPRoom *)sender{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}

- (void)xmppRoomDidJoin:(XMPPRoom *)sender{
    DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);
}

更新

配置房间：

之后：

[xmppRoom joinRoomUsingNickname:self.xmppStream.myJID.user
                        history:history
                       password:nil];

添加：

[xmppRoom fetchConfigurationForm];

并检查响应：

- (void)xmppRoom:(XMPPRoom *)sender didFetchConfigurationForm:(NSXMLElement *)configForm{
    DDLogVerbose(@"%@: %@ -> %@", THIS_FILE, THIS_METHOD, sender.roomJID.user);
}

检查 configForm 对象，根据需要进行更改，然后使用 [sender configureRoomUsingOptions:newConfig]; 发送它。

示例： 如果要更改配置以使房间持久化，可以添加类似以下内容：

NSXMLElement *newConfig = [configForm copy];
NSArray* fields = [newConfig elementsForName:@"field"];
for (NSXMLElement *field in fields) {
    NSString *var = [field attributeStringValueForName:@"var"];
    if ([var isEqualToString:@"muc#roomconfig_persistentroom"]) {
        [field removeChildAtIndex:0];
        [field addChild:[NSXMLElement elementWithName:@"value" stringValue:@"1"]];
    }
}
[sender configureRoomUsingOptions:newConfig];

（我不熟悉NSXMLElement，所以可能有更好的方法来更改值）
