iOS XMPP房间的创建注意事项及误区
_m_xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:_xmppRoomDatajid:RoomJID dispatchQueue:queue2 ];
那我这里就详细介绍一下各个参数该如何设置.
第一个参数，是XMPPRoomCoreDataStorage类型，他是为这个房间分配一个coredata的数据库，但由于我是用自己的数据库，所以就用
_xmppRoomData = [[XMPPRoomCoreDataStoragealloc] initWithInMemoryStore];
来实例化之。
第二个参数则是Room的JID这个需要自己分配，不能跟服务器已经有的JID重复。
第三个参数则是房间所在队列，此参数特别重要，请大家一定注意。xmpp的提供了一个IOS 的demo，此demo很大程度上误导了大家，因为他初始化queue都用的是
dispatch_get_main_queue()
这是主线程队列（没错就是管UI更新的那个），他可能是为了图写domo方便所以才用这个队列。但是实际的聊天软件，你敢在写主线程队列里面？一个也许还行，20个房间呢？程序根本就卡到爆。所以我建议大家重新新建一个串行队列
e.g :
queue2 =dispatch_queue_create("com.我的工程.RoomQueue",NULL); // 串行queue
你也许想问，为什么一定要用串行？并行为什么不行？因为，stream也是串行的，也是一条一条往服务器送。
注意事项：最好自己抽象一个RoomClass,一个聊天室就是一个RoomClass对象，这样可以方便管控房间消息和加入离开房间等。下面贴上我自己的RoomClass和初始化RoomClass方法：
