Xcode 如何在特定位置禁用警告？

要在所有文件中禁用警告，我将使用以下预编译器头：

#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 */

\ifndef PrefixHeader\u pch
#定义PrefixHeader\u pch
#ifdef__OBJC__
#进口
#恩迪夫
#pragma-clang诊断已忽略“-Wmacro已重新定义”
#pragma-clang诊断被忽略“-Wobjc指定的初始值设定项”
#pragma-clang诊断被忽略“-Wshorten-64-to-32”
#pragma-clang诊断被忽略“-Wincompatible指针类型”
#pragma-clang诊断被忽略“-Wprotocol”
#pragma-clang诊断被忽略“-Wmissing选择器名称”
#endif/*PrefixHeader\u pch*/

我需要对位于特定文件夹中的文件禁用警告，例如

$（SRCROOT）/wrapper/

。我该怎么做
