我创建了一个 iPhone 应用程序并将谷歌驱动库集成到项目中，并且还在构建设置中进行了所需的设置。我在编译时遇到错误。请任何人都可以帮助我

     }];

    NSLog(@"Click on the login button");
}

我在模拟器上运行这段代码。所以我遇到了错误

 ld: duplicate symbol _OBJC_METACLASS_$_GTLDriveAbout in
   /Users/bcod/Library/Developer/Xcode/DerivedData/GoogleDDemo-frrwjztsgtylsxbmkifnctrxzjfh/Build/Intermediates/GoogleDDemo.build/Debug-iphonesimulator/GoogleDDemo.build/Objects-normal/i386/GTLDriveAbout.o
   and

   for architecture i386
