如何使用指定数量的邮件加入聊天室

Question

目前我正在加入这样的聊天室。

_xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:_roomStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [_xmppRoom activate:[self appDelegate].xmppStream];
    [_xmppRoom addDelegate:self
            delegateQueue:dispatch_get_main_queue()];

    NSString *profileId = @"123456";

    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [_xmppRoom joinRoomUsingNickname:profileId history:nil password:myPassword];

我想只检索指定数量的邮件作为聊天记录。目前它正在一次检索所有消息，这导致长聊天历史记录问题。

你能帮帮我吗？

这是我找到的答案。您已发送指定了最大节的XML元素。

这是代码。

    XMPPJID *roomJID = [XMPPJID jidWithString:roomID];
    _xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:_roomStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [_xmppRoom activate:[self appDelegate].xmppStream];
    [_xmppRoom addDelegate:self
            delegateQueue:dispatch_get_main_queue()];

    NSString *profileId = @"123456";

    NSString *myPassword = [[NSUserDefaults standardUserDefaults] stringForKey:@"userPassword"];
    [[NSUserDefaults standardUserDefaults] synchronize];


    NSXMLElement *history = [NSXMLElement elementWithName:@"history"];
    [history addAttributeWithName:@"maxstanzas" stringValue:@"10"];
    [_xmppRoom joinRoomUsingNickname:profileId history:history password:myPassword];
