Xcode Apple Mach-O鏈接器錯誤1

Question

每當我嘗試構建應用程序重命名我的項目后，我得到一個Apple Mach-O鏈接器錯誤下面是Xcode本身的輸出

感謝您的幫助，因為我是Xcode和快速語言的新手。 玩笑

Answer 1

重命名后，只需轉到您的項目文件（您將看到標簽：常規，功能，信息等）

並在左側列表中選擇YourAppTests

你可能會看到這張照片

將Host Application設置為您的項目名稱，就是這樣。

Answer 2

我在嘗試實施AdMob廣告時偶爾會遇到Apple Mach-O Linker Error 1 。 我處理它的方式是首先進入我的應用程序的構建設置並找到“庫搜索路徑”並清除所有搜索路徑。 然后我將AdMob文件夾重新添加到項目中，錯誤消失了。

現在顯然你的情況有點不同了。 就個人而言，我會將文件重命名為以前的名稱。 如果錯誤仍然存​​在，則清除庫搜索路徑。 仍然是一個錯誤？ 我在收到錯誤時所做的是創建一個名為I want的新Xcode項目，然后將所有文件復制到新項目中。 這是一個簡單的過程，特別是如果你是一個初學者，它可能不會花太長時間。 我希望這有幫助！
