- (void)xmppMUC:(XMPPMUC *) sender roomJID:(XMPPJID *) roomJID didReceiveInvitation:(XMPPMessage *)message 
{ 
}

Answer 1

这是您接受群组邀请的方式。您只需要激活您的 XMPPMUC 协议，如下所示：

XMPPMUC * xmppMUC = [[XMPPMUC alloc] initWithDispatchQueue:dispatch_get_main_queue()];
[xmppMUC   activate:_xmppStream];
[xmppMUC addDelegate:self delegateQueue:dispatch_get_main_queue()];

要接受 MUC 的传入邀请：

- (void)xmppMUC:(XMPPMUC *)sender didReceiveRoomInvitation:(XMPPMessage *)message
{
    NSXMLElement * x = [message elementForName:@"x" xmlns:XMPPMUCUserNamespace];
    NSXMLElement * invite  = [x elementForName:@"invite"];
    if (!isEmpty(invite))
    {
        NSString * conferenceRoomJID = [[message attributeForName:@"from"] stringValue];
        [self joinMultiUserChatRoom:conferenceRoomJID];

    }
}

- (void) joinMultiUserChatRoom:(NSString *) newRoomName
{
    XMPPJID *roomJID = [XMPPJID jidWithString:newRoomName];
    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];
    xmppRoom = [[XMPPRoom alloc]
                initWithRoomStorage:roomMemoryStorage
                jid:roomJID
                dispatchQueue:dispatch_get_main_queue()];
    [xmppRoom activate:[self xmppStream]];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppRoom joinRoomUsingNickname:@"YOUR NICKNAME" history:nil];
}

Answer 2

接受传入的邀请：

- (void)xmppMUC:(XMPPMUC *)sender roomJID:(XMPPJID *) roomJID didReceiveInvitation:(XMPPMessage *)message
{ XMPPRoom *mu = [[XMPPRoom alloc] initWithRoomStorage:xmpproomMstorage jid:roomJID
                                           dispatchQueue:dispatch_get_main_queue()];

    [mu   activate:xmppStream];
    [mu   addDelegate:self delegateQueue:dispatch_get_main_queue()];

    self.toSomeOne = roomJID;

    [mu activate: self.xmppStream];
    [mu fetchConfigurationForm];
    [mu addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [mu joinRoomUsingNickname:xmppStream.YourJid.user history:nil password:@"Your Password"];
self.toSomeOne = roomJID;
    XMPPPresence *presence = [XMPPPresence presence];
   [[self xmppStream] sendElement:presence];
    [xmppRoster addUser:roomJID  withNickname:roomJID.full];
    [self goOnline];
}

Answer 3

就我而言，我需要同时使用两个答案并定义 self like

@interface XMPPDelegate : NSObject <XMPPMUCDelegate>

激活 XMPPMUC 协议如下：

XMPPMUC * xmppMUC = [[XMPPMUC alloc] 
initWithDispatchQueue:dispatch_get_main_queue()];
[xmppMUC   activate:_xmppStream];
[xmppMUC addDelegate:self delegateQueue:dispatch_get_main_queue()];

接收加入消息：

- (void)xmppMUC:(XMPPMUC *)sender roomJID:(XMPPJID *) roomJID didReceiveInvitation:(XMPPMessage *)message
{
    DDLogDebug(@"%@", message);
    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];
    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage jid:roomJID dispatchQueue:dispatch_get_main_queue()];
    [xmppRoom activate:xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppRoom joinRoomUsingNickname: xmppStream.myJID.user history:nil password:password];
    XMPPPresence *presence = [XMPPPresence presence];
    [[self xmppStream] sendElement:presence];
    [xmppRoster addUser:roomJID  withNickname:roomJID.full];
    [self goOnline];
}
