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

?
1
- (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：

?
1
2
3
4
<presence from="">
　　<show>这里是显示的内容<show />
　　<status>这里是显示的状态<status />
<presence />

presence 的状态：

available 上线

away 离开

do not disturb 忙碌

unavailable 下线

    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

?

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 <message /> 标签内，例如：

?
1
2
3
<message type="chat" to="xiaoming@example.com">
　　<body>Hello World!<body />
<message />

?

- (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];
}

                }  
            }  
        }  
         
        //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
 [_xmppAutoPing   deactivate];
  [_xmppAutoPing   removeDelegate: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");
}
