【iOS XMPP】使用XMPPFramewok（四）：收发消息

收发消息

 

接收消息

通过实现 

- (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

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message {
    NSString *messageBody = [[message elementForName:@"body"] stringValue];
}

 

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：

<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];
}
