public void JoinConversation(string id)
{
	conversation = AVIMConversation.CreateWithoutData(id, imClient);
	imClient.JoinAsync(conversation);
}

public void LeaveConversation(string id)
{
	imClient.LeaveAsync(conversation);
}

现在遇到的问题是：用LeaveConversation方法离开后再也不能返回会话了，也不能再向Leancloud后台发送消息了，是我JoinConversation方法写的不对吗，求大神解析，谢谢！

补充：有个错误消息，我对话的id一直没变过
