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
|
1
2
3
|
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket... |
然后
|
1
|
- (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
|
1
|
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender |
1.3上线
实现 - (void)xmppStreamDidAuthenticate:(XMPPStream *)sender 委托方法
|
1
2
3
4
|
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender { XMPPPresence *presence = [XMPPPresence presenceWithType:@"available"]; [self.xmppStream sendElement:presence];} |
1.4退出并断开连接
|
1
2
3
4
5
6
|
- (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
|
1
2
3
|
- (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
通过实现
|
1
|
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message; |
方法
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
|
1
2
3
|
- (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：
|
1

3
4
5
6
7
8
9
10
|
- (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

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。
