原始地址：XMPPFrameWork IOS 开发（七）消息回执
请参考：XEP-0184协议
协议内容：
发送消息时附加回执请求
[cpp] view plain copy print?
<message
from='northumberland@shakespeare.lit/westminster'
id='richard2-4.1.247'
to='kingrichard@royalty.england.lit/throne'>
<body>My lord, dispatch; read o'er these articles.</body>
<request xmlns='urn:xmpp:receipts'/>
</message>
代码实现
[cpp] view plain copy print?
NSString *siID = [XMPPStream generateUUID];
//发送消息
XMPPMessage *message = [XMPPMessage messageWithType:@"chat" to:jid elementID:siID];
NSXMLElement *receipt = [NSXMLElement elementWithName:@"request" xmlns:@"urn:xmpp:receipts"];
[message addChild:receipt];
[message addBody:@"测试"];
[self.xmppStream sendElement:message];
收到回执请求的消息，发送回执
[cpp] view plain copy print?
<message
from='kingrichard@royalty.england.lit/throne'
id='bi29sg183b4v'
to='northumberland@shakespeare.lit/westminster'>
<received xmlns='urn:xmpp:receipts' id='richard2-4.1.247'/>
</message>
代码实现
[cpp] view plain copy print?
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
//回执判断
NSXMLElement *request = [message elementForName:@"request"];
if (request)
{
if ([request.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回执
{
//组装消息回执
XMPPMessage *msg = [XMPPMessage messageWithType:[message attributeStringValueForName:@"type"] to:message.from elementID:[message attributeStringValueForName:@"id"]];
NSXMLElement *recieved = [NSXMLElement elementWithName:@"received" xmlns:@"urn:xmpp:receipts"];
[msg addChild:recieved];
//发送回执
[self.xmppStream sendElement:msg];
}
}else
{
NSXMLElement *received = [message elementForName:@"received"];
if (received)
{
if ([received.xmlns isEqualToString:@"urn:xmpp:receipts"])//消息回执
{
//发送成功
NSLog(@"message send success!");
}
}
}
//消息处理
//...
}
