錯誤在Xcode 6.1中使用Google API Objective-C客戶端導入Google Drive SDK

Question

導入Google Drive SDK以及Google Objective-C客戶端API時出現以下錯誤。我使用帶有Swift的iOS 8.1的Xcode 6.1作爲我的主要語言。我已經遵循Google Drive SDK頁面中的所有步驟，但仍然無法正常工作。有鏈接器錯誤，我不知道如何解決這個問題。有想法該怎麼解決這個嗎？

Answer 1

一些實驗後，我發現瞭如何使它在6.1的Xcode工作。以下是我嘗試過的方法。我正在記錄所有，因爲我不知道哪一個實際上起作用。

1. 單獨打開GTL.xcodeproj。 Xcode會給你一個警告，並會要求你更新你的設置。選擇更新它。
2. 然後導航到GTL項目（目標窗口）並單擊GTLTouchStaticLib並在支持的平臺中選擇iOS（默認情況下，它被設置爲OS X）。
3. 關閉GTL項目，然後重新打開自己的項目。清潔和建立和中提琴鏈接器不再抱怨，一切都應該工作正常。

我不確定是否需要（1），但由於我一起完成了所有這些步驟，我不確定哪個是實際解決問題的人。

我希望這可以解決其他人的問題。
