加入MUC会议室时XMPP Stream断开连接

时间:2016-01-05 11:40:09

标签: ios objective-c xmpp xmppframework

我正在使用XMPPFramework在我的应用中实现群聊功能。一对一聊天工作正常,但当我通过调用[xmppRoom joinRoomUsingNickname]加入一个房间时,流会断开连接而不会出现任何错误。

我也实现了xmppStreamDidDisconnect:withError,但它仍然给出了nil错误。由于流断开连接,用户在加入房间后也会立即离开房间。我也在使用重新连接模块,但是当它重新连接时,房间不会自动加入。

我正在使用pidgin来测试它,但它在那里工作正常。什么可能是立即断开连接的原因?

PS:我正在iOS 9上运行的iPhone 5上测试它

更新:现在出现以下错误 -

  

错误Domain = GCDAsyncSocketErrorDomain Code = 7“Socket由远程关闭   peer“UserInfo = {NSLocalizedDescription =由远程对等方关闭的套接字}

通常,当服务器关闭连接时,会出现此错误。 服务器关闭连接有两个原因:

  1. 如果客户端闲置,您不会定期发送ping。
  2. 您正在使用相同的凭据从某个不同的客户端登录, 并在服务器设置中具有以下设置: 始终踢 - 如果存在资源冲突,请立即踢另一个 资源。在服务器&gt;服务器设置&gt;资源政策。
  3. 请检查服务器设置。 将其用于服务器设置http://docs.ejabberd.im/admin/guide/installation/

    并检查项目中的App Transport Security Setting。如果没有添加,则将以下代码添加到info.plist

     <?xml version="1.0" encoding="UTF-8"?>

实际的问题是,在创建房间之后,我正在改变房间的主题。在删除更改房间主题的代码后,它开始正常工作。这是我正在使用的代码 -

-(XMPPRoom *)createRoom:(XMPPJID *)roomJid withSubject:(NSString*)subject{
    XMPPRoomMemoryStorage *roomStorage = [[XMPPRoomMemoryStorage alloc]init];
    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomStorage
                                                           jid:roomJid
                                                 dispatchQueue:dispatch_get_main_queue()];

    [xmppRoom activate:self.xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
//    if(subject){
//        [xmppRoom changeRoomSubject:subject];
//    }
    return xmppRoom;
}
-(GroupCore *)createRoomAndGroup:(XMPPJID *)roomJid withSubject:(NSString*)subject{
    XMPPRoom* xmppRoom = [self createRoom:roomJid withSubject:subject];
    GroupCore* group = [appDelegate.coreDataController addGroup:xmppRoom withOptions:CreateOnly];
    if(!xmppRoom.roomSubject){
        group.name = subject;
    }
    //[appDelegate saveContext];
//    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 5 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
//        [group joinRoom];
//    });
    return group;
}
