问题
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)?
回答1:
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;
}
You can get a C++ version with
clang -rewrite-objc main.c
which is great to see how objective-C is implemented. Most of the file will be just C.
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.
