您可以反汇编二进制文件并重新获得汇编源代码，但是无法取回原始的Objective-C结构化源代码.
您可能需要尝试 Hopper .我还没有亲自尝试过，但是 Mike阿什说很好.

You can disassemble a binary and get back assembly source, but there is no way to get back your original Objective-C structured source code.
You may want to give Hopper a try. I didn't try it personally yet but Mike Ash says it's good.
