XMPPFramework是一个OS X/iOS平台的开源项目,使用Objective-C实现了XMPP协议(RFC-3920),同时还提供了用于读写XML的工具,大大简化了基于XMPP的通信应用的开发。
1. 登录和好友上下线1.1XMPP中常用对象们
- XMPPStream:xmpp基础服务类
- XMPPRoster:好友列表类
- XMPPRosterCoreDataStorage:好友列表(用户账号)在core data中的操作类
- XMPPvCardCoreDataStorage:好友名片(昵称,签名,性别,年龄等信息)在core data中的操作类
- XMPPvCardTemp:好友名片实体类,从数据库里取出来的都是它
- xmppvCardAvatarModule:好友头像
- XMPPReconnect:如果失去连接,自动重连
- XMPPRoom:提供多用户聊天支持
- XMPPPubSub:发布订阅
1.2登录操作,也就是连接xmpp服务器- (void)connect {if (self.xmppStream == nil) {self.xmppStream = [[XMPPStream alloc] init];[self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];}if (![self.xmppStream isConnected]) {NSString *username = [[NSUserDefaults standardUserDefaults] objectForKey:@"username"];XMPPJID *jid = [XMPPJID jidWithUser:username domain:@"lizhen" resource:@"Ework"];[self.xmppStream setMyJID:jid];[self.xmppStream setHostName:@"10.4.125.113"];NSError *error = nil;if (![self.xmppStream connect:&error]) {NSLog(@"Connect Error: %@", [[error userInfo] description]);}}}connect成功之后会依次调用XMPPStreamDelegate的方法,首先调用
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
然后
- (void)xmppStreamDidConnect:(XMPPStream *)sender
在该方法下面需要使用xmppStream 的authenticateWithPassword方法进行密码验证,成功的话会响应delegate的方法,就是下面这个
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
1.3上线实现 - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender 委托方法
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender {XMPPPresence *presence = [XMPPPresence presenceWithType:@"available"];[self.xmppStream sendElement:presence];}1.4退出并断开连接- (void)disconnect {XMPPPresence *presence = [XMPPPresence presenceWithType:@"unavailable"];[self.xmppStream sendElement:presence]; [self.xmppStream disconnect];}1.5好友状态获取好友状态,通过实现
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence ...
方法,当接收到 presence 标签的内容时,XMPPFramework 框架回调该方法
一个 presence 标签的格式一般如下:

presence 的状态:
- available 上线
- away 离开
- do not disturb 忙碌
- unavailable 下线
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {NSString *presenceType = [presence type];NSString *presenceFromUser = [[presence from] user];if (![presenceFromUser isEqualToString:[[sender myJID] user]]) {if ([presenceType isEqualToString:@"available"]) {//} else if ([presenceType isEqualToString:@"unavailable"]) {//}}}2. 接收消息和发送消息2.1接收消息当接收到 message 标签的内容时,XMPPFramework 框架回调该方法
根据 XMPP 协议,消息体的内容存储在标签 body 内
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message {NSString *messageBody = [[message elementForName:@"body"] stringValue];}2.2发送消息发送消息,我们需要根据 XMPP 协议,将数据放到标签内,例如:

- (void)sendMessage:(NSString *) message toUser:(NSString *) user {NSXMLElement *body = [NSXMLElement elementWithName:@"body"];[body setStringValue:message];NSXMLElement *message = [NSXMLElement elementWithName:@"message"];[message addAttributeWithName:@"type" stringValue:@"chat"];NSString *to = [NSString stringWithFormat:@"%@@example.com", user];[message addAttributeWithName:@"to" stringValue:to];[message addChild:body];[self.xmppStream sendElement:message];}3. 获取好友信息和删除好友3.1好友列表和好友名片[_xmppRoster fetchRoster];//获取好友列表//获取到一个好友节点- (void)xmppRoster:(XMPPRoster *)sender didRecieveRosterItem:(NSXMLElement *)item//获取完好友列表- (void)xmppRosterDidEndPopulating:(XMPPRoster *)sender//到服务器上请求联系人名片信息- (void)fetchvCardTempForJID:(XMPPJID *)jid;//请求联系人的名片,如果数据库有就不请求,没有就发送名片请求- (void)fetchvCardTempForJID:(XMPPJID *)jid ignoreStorage:(BOOL)ignoreStorage;//获取联系人的名片,如果数据库有就返回,没有返回空,并到服务器上抓取- (XMPPvCardTemp *)vCardTempForJID:(XMPPJID *)jid shouldFetch:(BOOL)shouldFetch;//更新自己的名片信息- (void)updateMyvCardTemp:(XMPPvCardTemp *)vCardTemp;//获取到一盒联系人的名片信息的回调- (void)xmppvCardTempModule:(XMPPvCardTempModule *)vCardTempModule didReceivevCardTemp:(XMPPvCardTemp *)vCardTempforJID:(XMPPJID *)jid
3.2添加好友 //name为用户账号- (void)XMPPAddFriendSubscribe:(NSString *)name{//XMPPHOST 就是服务器名, 主机名XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",name,XMPPHOST]];//[presence addAttributeWithName:@"subscription" stringValue:@"好友"];[xmppRoster subscribePresenceToUser:jid]; }3.3收到添加好友的请求 - (void)xmppRoster:(XMPPRoster *)sender didReceivePresenceSubscriptionRequest:(XMPPPresence *)presence{//取得好友状态NSString *presenceType = [NSString stringWithFormat:@"%@", [presence type]]; //online/offline//请求的用户NSString *presenceFromUser =[NSString stringWithFormat:@"%@", [[presence from] user]];NSLog(@"presenceType:%@",presenceType); NSLog(@"presence2:%@ sender2:%@",presence,sender); XMPPJID *jid = [XMPPJID jidWithString:presenceFromUser];//接收添加好友请求[xmppRoster acceptPresenceSubscriptionRequestFrom:jid andAddToRoster:YES]; }3.4删除好友//删除好友,name为好友账号- (void)removeBuddy:(NSString *)name { XMPPJID *jid = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@%@",name,XMPPHOST]]; [self xmppRoster] removeUser:jid]; }4. 聊天室初始化聊天室XMPPJID *roomJID = [XMPPJID jidWithString:ROOM_JID]; xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:self jid:roomJID]; [xmppRoom activate:xmppStream];[xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
创建聊天室成功- (void)xmppRoomDidCreate:(XMPPRoom *)sender{DDLogInfo(@"%@: %@", THIS_FILE, THIS_METHOD);}加入聊天室,使用昵称 [xmppRoom joinRoomUsingNickname:@"quack" history:nil];
获取聊天室信息
- (void)xmppRoomDidJoin:(XMPPRoom *)sender{[xmppRoom fetchConfigurationForm];[xmppRoom fetchBanList];[xmppRoom fetchMembersList];[xmppRoom fetchModeratorsList];}如果房间存在,会调用委托 // 收到禁止名单列表- (void)xmppRoom:(XMPPRoom *)sender didFetchBanList:(NSArray *)items;// 收到好友名单列表- (void)xmppRoom:(XMPPRoom *)sender didFetchMembersList:(NSArray *)items;// 收到主持人名单列表- (void)xmppRoom:(XMPPRoom *)sender didFetchModeratorsList:(NSArray *)items;
房间不存在,调用委托 - (void)xmppRoom:(XMPPRoom *)sender didNotFetchBanList:(XMPPIQ *)iqError;- (void)xmppRoom:(XMPPRoom *)sender didNotFetchMembersList:(XMPPIQ *)iqError;- (void)xmppRoom:(XMPPRoom *)sender didNotFetchModeratorsList:(XMPPIQ *)iqError;
离开房间[xmppRoom deactivate:xmppStream];
XMPPRoomDelegate的其他代理方法:离开聊天室 - (void)xmppRoomDidLeave:(XMPPRoom *)sender{DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);}新人加入群聊
- (void)xmppRoom:(XMPPRoom *)sender occupantDidJoin:(XMPPJID *)occupantJID{DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);}有人退出群聊 - (void)xmppRoom:(XMPPRoom *)sender occupantDidLeave:(XMPPJID *)occupantJID{DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);}有人在群里发言 - (void)xmppRoom:(XMPPRoom *)sender didReceiveMessage:(XMPPMessage *)message fromOccupant:(XMPPJID *)occupantJID{DDLogVerbose(@"%@: %@", THIS_FILE, THIS_METHOD);}5. 消息回执这个是XEP-0184协议的内容。协议内容:
发送消息时附加回执请求

代码实现
NSString *siID = [XMPPStream generateUUID];//发送消息XMPPMessage *message = [XMPPMessage messageWithType:@"chat" to:jid elementID:siID];NSXMLElement *receipt = [NSXMLElement elementWithName:@"request" xmlns:@"urn:xmpp:receipts"];[message addChild:receipt];[message addBody:@"测试"];[self.xmppStream sendElement:message];
收到回执请求的消息,发送回执

代码实现
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{//回执判断NSXMLElement *request = [message elementForName:@"request"];if (request){if ([request.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回执{//组装消息回执XMPPMessage *msg = [XMPPMessage messageWithType:[message attributeStringValueForName:@"type"] to:message.from elementID:[message attributeStringValueForName:@"id"]];NSXMLElement *recieved = [NSXMLElement elementWithName:@"received" xmlns:@"urn:xmpp:receipts"];[msg addChild:recieved]; //发送回执[self.xmppStream sendElement:msg];}}else{NSXMLElement *received = [message elementForName:@"received"];if (received){if ([received.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回执{//发送成功NSLog(@"message send success!");} } }//消息处理 //... }6. 添加AutoPing为了监听服务器是否有效,增加心跳监听。用XEP-0199协议,在XMPPFrameWork框架下,封装了 XMPPAutoPing 和 XMPPPing两个类都可以使用,因为XMPPAutoPing已经组合进了XMPPPing类,所以XMPPAutoPing使用起来更方便。
//初始化并启动ping-(void)autoPingProxyServer:(NSString*)strProxyServer{_xmppAutoPing = [[XMPPAutoPingalloc] init];[_xmppAutoPingactivate:_xmppStream];[_xmppAutoPingaddDelegate:selfdelegateQueue: dispatch_get_main_queue()];_xmppAutoPing.respondsToQueries = YES;_xmppAutoPing.pingInterval=2;//ping 间隔时间if (nil != strProxyServer){_xmppAutoPing.targetJID = [XMPPJID jidWithString: strProxyServer ];//设置ping目标服务器,如果为nil,则监听socketstream当前连接上的那个服务器}}//卸载监听 [_xmppAutoPingdeactivate]; [_xmppAutoPingremoveDelegate:self];_xmppAutoPing = nil;//ping XMPPAutoPingDelegate的委托方法:- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender{NSLog(@"- (void)xmppAutoPingDidSendPing:(XMPPAutoPing *)sender");}- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender{NSLog(@"- (void)xmppAutoPingDidReceivePong:(XMPPAutoPing *)sender");}- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender{NSLog(@"- (void)xmppAutoPingDidTimeout:(XMPPAutoPing *)sender");}以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
