未定義符號錯誤 - NewsYC iOS App

我正在嘗試構建NewsYC iOS app。我可以讓它在模擬器中工作，但是當我定位到iPhone 5時，我會遇到一個未定義的符號錯誤。我對XCode和Objective C相當陌生，所以我不確定如何解決這個問題。我已經根據其他項目對這個錯誤進行了一些解讀，並在構建階段將libHNKit鏈接起來。不知道還有什麼需要改正的。未定義符號錯誤 - NewsYC iOS App

這是錯誤：

從終端做git submodule init; git submodule update後，在newsyc項目的文件導航器中選擇HNKit.xcocdeproj。然後點擊「Build Settings」，然後您應該看到「Build Active Architecture Only」旁邊的「多個值」。點擊它並將其設置爲「否」。
