如何从Objective-C代码中提取AST？ [英] How to extract AST from Objective-C code?

问题描述

我需要分析Objective-C静态代码，主要是AST，在查看可能的工具后，我发现来自LLVM的Clang工具可以转储AST，所以我使用终端测试它使用这个命令：

  clang -cc1 -ast-dump〜/ SomeTest.m 
  > 
 
 
但我收到此错误：
  /myusername/SomeTest.m:9：
 /Users/myusername/SomeTest.h:9:9：致命错误：找不到UIKit / UIKit.h文件
 #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 
  - （void）dealloc（CompoundStmt 0x7f86b183b110< /Users/myusername/SomeTest.m：14：1，line：16：1>） 
 
 
  - （void）didReceiveMemoryWarning（CompoundStmt 0x7f86b183b2a0< /Users/myusername/SomeTest.m：19：1，line：24：1>）
 
 
  - （void）viewDidUnload（CompoundStmt 0x7f86b183b430< /Users/myusername/SomeTest.m：37：1，line：41：1>）
 
 
  - shouldAutorotateToInterfaceOrientation：（id）interfaceOrientation（CompoundStmt 0x7f86b183b648< /Users/myusername/SomeTest.m：44：1，line：47：1>）
 
 
 @end 
 1错误生成。 
  
任何想法为什么我得到这个？我不介意使用任何工具从Objective-C代码提取AST，只要它是可靠的并提供输出的文档。
解决方案
编译器找不到UIKit框架。您必须告诉它使用它：
  clang -framework UIKit -cc1 -ast-dump〜/ SomeTest.m 
  
 
I need to analyze Objective-C static code, mainly AST, after looking into the possible tools I found out that Clang tool from LLVM can dump the AST, so I used the terminal to test it using this command:
clang -cc1 -ast-dump ~/SomeTest.m
but I'm getting this error:
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 struct __va_list_tag __va_list_tag;
typedef __va_list_tag __builtin_va_list[1];

@end

Any idea why I'm getting this? I don't mind using any tool to extract AST from Objective-C code as long as it is reliable and provide documentation for the output
解决方案
The compiler does not find the UIKit framework. You have to tell it to use it:
clang -framework UIKit -cc1 -ast-dump ~/SomeTest.m
