ios - XMPPFramework-Implementar chat en grupo(MUC)

objective-c

Question

Estoy trabajando en el cliente de chat iOS. ¿Alguien puede ayudarme con el chat multiusuario?

He implementado XMPPFramework de Robbiehanson.

¿Alguien puede, por favor, decirme cómo obtener una lista de grupos y crear un grupo en el servidor con este marco?

Gracias por adelantado.

Answer 1

Aquí hay una versión Swift:

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")
    }

Answer 2

Para obtener una lista de habitaciones:

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];

Compruebe la respuesta en el método de delegado:

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

unirse o crear espacio

XMPPRoomMemoryStorage * _roomMemory = [[XMPPRoomMemoryStorage alloc]init];
NSString* roomID = @"[email protected]";
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];

Verifique la respuesta en los métodos de delegado de XMPPRoom:

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

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

actualizar

para configurar una habitación:

después:

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

añadir:

[xmppRoom fetchConfigurationForm];

y verifique la respuesta en:

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

Revise el objeto configForm y cambie según sea necesario, luego envíelo con [sender configureRoomUsingOptions:newConfig];

Ejemplo: para cambiar la configuración y hacer que la habitación sea persistente, puede agregar algo como:

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];

(No estoy familiarizado con NSXMLElement, así que quizás haya una mejor manera de cambiar el valor)

+(void)getGroupRooms{
    NSError *error = nil;
    NSXMLElement *query = [[NSXMLElement alloc] initWithXMLString:@"<query xmlns=''http://jabber.org/protocol/disco#items''/>" error:&error];
    XMPPIQ *iq = [XMPPIQ iqWithType:@"get" to:[XMPPJID jidWithString:Jabber_groupChat_Domain_server] elementID:[[[PXMPPManager sharedInstance] xmppStream] generateUUID] child:query];
    [iq addAttributeWithName:@"from" stringValue:[[[PXMPPManager sharedInstance] xmppStream] myJID].full];
    [[[PXMPPManager sharedInstance] xmppStream] sendElement:iq];

//<iq type="get"

    if([iq isResultIQ])

                NSDictionary *dict = @{
                                       @"groupName" : roomName,

                [arrGroupName addObject:dict];
            }

            [ConversationsModel saveGroupName:arrGroupName];
        }
    }

    return false;
}
