收發消息
接收消息
通過實現
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message;
方法
當接收到 <message /> 標簽的內容時，XMPPFramework 框架回調該方法
根據 XMPP 協議，消息體的內容存儲在標簽 <body /> 內
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message { NSString *messageBody = [[message elementForName:@"body"] stringValue]; }
發送消息
發送消息，我們需要根據 XMPP 協議，將數據放到 <message /> 標簽內，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]; }
