如何在特定位置禁用警告？

Question

要禁用所有文件中的警告，我正在使用以下预编译器标头：

#ifndef PrefixHeader_pch
#define PrefixHeader_pch

#ifdef __OBJC__
#import <Foundation/Foundation.h>

#endif

#pragma clang diagnostic ignored "-Wmacro-redefined"
#pragma clang diagnostic ignored "-Wobjc-designated-initializers"
#pragma clang diagnostic ignored "-Wshorten-64-to-32"
#pragma clang diagnostic ignored "-Wincompatible-pointer-types"
#pragma clang diagnostic ignored "-Wprotocol"
#pragma clang diagnostic ignored "-Wmissing-selector-name"

#endif /* PrefixHeader_pch */

我需要为位于特定文件夹中的文件禁用警告，例如$(SRCROOT)/wrapper/。我怎么能这样做？
