接受聊天室邀请

Question

我可以使用XMPPFramework创建一个MUC,并使用下面的代码发送用户邀请请求加入该房间.

// Creating
AppDelegate *dele =(AppDelegate *) [[UIApplication sharedApplication]delegate];

xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:dele jid:[XMPPJID jidWithString:self.roomName] dispatchQueue:dispatch_get_main_queue()];
[xmppRoom addDelegate:dele delegateQueue:dispatch_get_main_queue()];
[xmppRoom activate:dele.xmppStream];
[xmppRoom joinRoomUsingNickname:self.myNick history:nil];

// Inviting
[xmppRoom inviteUser:[XMPPJID jidWithString:@"abc@host"] withMessage:@"Come Join me"];

用户"abc"如何知道他已收到邀请,他如何通过接受或拒绝对此做出反应？

我在XMPPFramework中找不到任何直接处理聊天室邀请的课程.我的研究表明,每当用户收到聊天室邀请时,都会调用xmmppStream的委托方法:

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

在该消息中,我检查它是否包含名为"invite"的NSXMLElement,如果它包含,则我向用户发送回调.然后我创建聊天室,其名称与用户收到邀请的聊天室名称相同,并进入新创建的房间.它工作正常,但安静冗长,不安静有效.我想知道是否有可用XMPPFramework一类在这里它可以单独处理的聊天室邀请.例如,检测,接受和拒绝房间邀请.

我提取房间名称的代码:

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
    NSXMLElement * x = [message elementForName:@"x" xmlns:XMPPMUCUserNamespace];
    NSXMLElement * invite  = [x elementForName:@"invite"];
    NSXMLElement * decline = [x elementForName:@"decline"];
    NSXMLElement * directInvite = [message elementForName:@"x" xmlns:@"jabber:x:conference"];
    NSString *msg = [[message elementForName:@"body"]stringValue];
    NSString *from = [[[message attributeForName:@"from"]stringValue];
    if (invite || directInvite)
    {
        [self createAndEnterRoom:from Message:msg];
        return;
    }
    [self.delegate newMessageRecieved:msg];
}

Answer 1

对于房间邀请和拒绝,实施XMPPMUCDelegate及其方法-xmppMUC:didReceiveRoomInvitation:和-xmppMUC:didReceiveRoomInvitationDecline:.

要获得房间JID,请调用[message from];

要加入房间,请实例化XMPPRoom并调用-joinRoomUsingNickname:history:.

然后让你的房间委托类实现XMPPRoomDelegate,并实现一些委托方法来处理在房间里接收消息.

看起来目前没有更自动的方式来响应邀请.

更新:委托回调现在接收房间JID作为参数,稍微澄清语义.

- (void)xmppMUC:(XMPPMUC *)sender roomJID:(XMPPJID *) roomJID didReceiveInvitation:(XMPPMessage *)message;
- (void)xmppMUC:(XMPPMUC *)sender roomJID:(XMPPJID *) roomJID didReceiveInvitationDecline:(XMPPMessage *)message;
