Answer 1

您可以发送短信到这种方式与您groupJID我将消息发送到特定的人群（例如，组名@域名）例如

**Swift 3.0** 

    let completeMessage = DDXMLElement.element(withName: "message") as! DDXMLElement   

    completeMessage.addAttribute(withName: "id", stringValue: messageID!) 
    completeMessage.addAttribute(withName: "type", stringValue: 
      "groupchat") 

    completeMessage.addAttribute(withName: "to", stringValue: 
     recieverJID) 

    let body = DDXMLElement.element(withName: "body") as! DDXMLElement 

    body.stringValue = trimmedMessage 
    completeMessage.addChild(body) 
    sender.send(completeMessage) 

**Objective C** 

    NSXMLElement *message = [NSXMLElement elementWithName:@"message"]; 

    [message addAttributeWithName:@"id" stringValue: messageID]; 
    [message addAttributeWithName:@"type" stringValue:@"groupchat"]; 
    [message addAttributeWithName:@"to" stringValue:recieverJID]; 

    NSXMLElement *body = [NSXMLElement elementWithName:@"body"]; 
    [body setStringValue:messageStr]; 

    [message addChild:body]; 
    [sender sendElement:message];
