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
2
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];
} |

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。
