从.m（Objective-C）文件生成.c源 [英] Generate .c source from a .m (Objective-C) file

问题描述

是否可以使用GCC或Clang（或其他工具）从Objective-C源文件（.m）生成C源文件（.c）？

Is it possible to generate a C source file (.c) from an Objective-C source file (.m), using, maybe, GCC or Clang (or another tool)?

推荐答案

不，但你可能对C ++重写器感兴趣。给定一个目标C文件，让我们说：

No, but you may be interested in the C++ rewriter. Given an objective-C file, let's say:

#import <stdio.h>
int main() {
    void (^blk)(void) = ^{
        printf("hi");
    };
    blk();
    return 0;
}

您可以使用

clang -rewrite-objc main.c

这是很好看的如何实现objective-C。大多数文件将只是C.

which is great to see how objective-C is implemented. Most of the file will be just C.

一些结果表达式是密集的。您需要耐心，C知识和 Objective-C运行时参考。 http://cdecl.org/ 有助于小件。

Some of the resulting expressions are dense. You'll need patience, C knowledge, and the Objective-C Runtime Reference. http://cdecl.org/ helps with small pieces.
