xcode 架构 i386 的重复符号

duplicate symbols for architecture i386

提问by Ashutosh Bhatt

I am using GTL framework for using google GDrive. I copied all the files from the GTL.xcodeproject into my application after getting failed many times in importing that framework into my application. But still i am getting below mentioned error. I have searched all but found no duplicate files or anything. Please help here.

我正在使用 GTL 框架来使用 google GDrive。在将该框架导入我的应用程序时多次失败后，我将 GTL.xcodeproject 中的所有文件复制到我的应用程序中。但我仍然收到下面提到的错误。我已经搜索了所有但没有发现重复的文件或任何东西。请在这里帮忙。

Make sure you check the "Compile Sources" in your "Build Phases" section as well. Sometimes they get doubled in there (but appear only once in the project file explorer)

确保您也检查了“构建阶段”部分中的“编译源”。有时它们会在那里加倍（但在项目文件资源管理器中只出现一次）

Try to delete all the files/folders from your project location and also remove references from XCode project.

尝试从项目位置删除所有文件/文件夹，并从 XCode 项目中删除引用。

Then, copy library folder to project location and in XCode, click on "Add files ..." and choose the new added folder in project location.

然后，将库文件夹复制到项目位置，在 XCode 中，单击“添加文件...”并在项目位置选择新添加的文件夹。
