ios - 错误 : unreachable because it has no entry points

使用Swift我得到了我的“TableViewController”无法访问的错误,因为它没有入口点,也没有通过[UIStoryboardinstantiateViewControllerWithIdentifier]的运行时访问。在我的ViewController类中,建议在更改instantiateViewController(withIdentifier)中的instantiateViewController(withIdentfier...)时修复它。我应该这样做还是如何解决这个问题? 最佳答案 您需要在Storyboard

c# - Cannot modify the logical children for this node at this time because a tree walk is in progress 是什么意思?

我正在后台工作线程的完成方法中设置对象的DataContext。出于某种原因,我收到一条错误消息:此时无法修改此节点的逻辑子节点,因为正在进行指向Chart1.DataContext=allDates行的树遍历。atreewalkisinprogress是什么意思?我也尝试过使用Dispatcher操作进行此设置,但出现了同样的错误……有什么想法吗?Google对此错误消息一无所获。导致此问题的代码是Microsoft图表工具包的内部代码...我想知道我是否在他们的控件中发现了错误...没有调度器:voidbg_RunWorkerCompleted(objectsender,RunWo

我用C#编写了一个IP多播应用程序。它编译得很好,但在运行时这一行:sock.SetSocketOption(SocketOptionLevel.IP,SocketOptionName.AddMembership,newMulticastOption(IPAddress.Parse("224.100.0.1")));抛出未处理的套接字异常:Anoperationonasocketcouldnotbeperformedbecausethesystemlackedsufficientbufferspaceorbecauseaqueuewasfull我在Google中搜索错误,有人建议删除可
