我正在尝试构建NewsYC iOS 应用程序。我可以让它在模拟器中工作，但是当我瞄准我的 iPhone 5 时，我得到一个未定义的符号错误。我对 XCode 和 Objective C 很陌生，所以我不确定如何解决这个问题。我已经阅读了一些关于其他项目的错误信息，并在构建阶段链接了 libHNKit。不太确定还需要发生什么来纠正这个问题。

这是错误：

从终端完成后git submodule init; git submodule update，在 newsyc 项目的文件导航器中选择 HNKit.xcocdeproj。然后单击“构建设置”，然后您应该会在“仅构建活动架构”旁边看到“多个值”。单击它并将其设置为“否”。
