Xcode中測試的鏈接器錯誤

Question

我按照TDD網站上使用xcode / appcode進行測試的說明進行操作。 我順利通過了最初的部分，並開始在自己的項目中進行實驗，但是我一直遇到鏈接錯誤，無法確定從何而來？

我得到的輸出是這個

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我嘗試查看缺少的“源”或“鏈接的庫”，但找不到任何東西。 有人知道還有什么問題嗎？

謝謝！

您是否嘗試過以下方法：

轉到XCode，在Project下->清理並再次構建解決方案。
