XMPPFramework – 实现群聊（MUC）

我正在iOS聊天客户端上工作。 任何人都可以请帮我多用户聊天？

我已经实现了Robbiehanson的XMPPFramework。

任何人都可以让我知道如何获得组的列表，并创build一个在这个框架的服务器组？

提前致谢。

Answer 1

获取房间清单：

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]; 

在委托方法中检查响应：

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

join或创造空间

 XMPPRoomMemoryStorage * _roomMemory = [[XMPPRoomMemoryStorage alloc]init]; NSString* roomID = @"[e-mail]"; 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委托方法中的响应：

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

更新

configuration房间：

后：

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

加：

 [xmppRoom fetchConfigurationForm]; 

并检查回应：

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

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

例如：改变configuration，使房间持久，你可以添加如下内容：

 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，所以也许有更好的方法来改变这个值）

这是一个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") }

 +(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" //to="conference.cnr-uat.panamaxil.com" //id="DF27F28E-488D-4DAB-AA03-399A4CDE91B3" //from="[e-mail]/iphone"> //<query xmlns="http://jabber.org/protocol/disco#items"/> //</iq> } #pragma - mark XMPPStreamDelegate Methods - (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq{ // NSLog(@"Did receive IQ"); if([iq isResultIQ]) { if([iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#items"]) { NSLog(@"Jabber Server's Capabilities: %@", [iq XMLString]); NSXMLElement *queryElement = [iq elementForName:@"query" xmlns:@"http://jabber.org/protocol/disco#items"]; NSArray *items = [queryElement elementsForName:@"item"]; NSMutableArray *arrGroupName = [[NSMutableArray alloc] init]; for (NSXMLElement *i in items) { NSString *roomName = [i attributeStringValueForName:@"name"]; NSString *jidString = [i attributeStringValueForName:@"jid"]; //XMPPJID *jid = [XMPPJID jidWithString:jidString]; NSDictionary *dict = @{ @"groupName" : roomName, @"groupJID" : jidString, }; [arrGroupName addObject:dict]; } [ConversationsModel saveGroupName:arrGroupName]; } } return false; }
