接受聊天室邀请

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。 我想知道这里是否有一个XMPPFramework类可以单独处理聊天室邀请。 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]; }

对于房间邀请和拒绝，实现XMPPMUCDelegate及其方法-xmppMUC:didReceiveRoomInvitation: -xmppMUC:didReceiveRoomInvitationDecline: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房间中的接收消息。

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，稍微澄清了语义。 

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

只需添加以下代码 

 if ([presenceType isEqualToString:@"subscribe"]) { [_chatDelegate newBuddyOnline:[NSString stringWithFormat:@"%@@%@", presenceFromUser, @"localhost"]]; NSLog(@"presence user wants to subscribe %@",presenceFromUser); [xmppRoster acceptPresenceSubscriptionRequestFrom:[presence from] andAddToRoster:YES]; //For reject button // [xmppRoster rejectPresenceSubscriptionRequestFrom:[tmpPresence from]]; }

在方法内部 

  - (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence ; method
