objective-c - 如何从 Objective-C 代码中提取 AST？

Question

我需要分析 Objective-C 静态代码，主要是 AST，在查看可能的工具后我发现 LLVM 的 Clang 工具可以转储 AST，所以我使用终端使用以下命令对其进行测试:

clang -cc1 -ast-dump ~/SomeTest.m

但是我收到了这个错误:

In file included from /Users/myusername/SomeTest.m:9:
/Users/myusername/SomeTest.h:9:9: fatal error: 'UIKit/UIKit.h' file not found
#import <UIKit/UIKit.h>
        ^
typedef __int128_t __int128_t;
typedef __uint128_t __uint128_t;
typedef SEL *SEL;
typedef id id;
typedef Class *Class;
struct __va_list_tag {
    unsigned int gp_offset;
    unsigned int fp_offset;
    void *overflow_arg_area;
    void *reg_save_area;
};
typedef struct __va_list_tag __va_list_tag;
typedef __va_list_tag __builtin_va_list[1];
@interface just4testViewController@end
@implementation just4testViewController

知道我为什么会收到这个吗？我不介意使用任何工具从 Objective-C 代码中提取 AST，只要它可靠并为输出提供文档即可

编译器没有找到 UIKit 框架。你必须告诉它使用它:

clang -framework UIKit -cc1 -ast-dump ~/SomeTest.m
