您可以反汇编二进制文件并取回汇编源代码，但无法取回原始的 Objective-C 结构化源代码.

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.

您可能想试试 Hopper.我还没有亲自尝试过，但是 Mike Ash 说这很好.

You may want to give Hopper a try. I didn't try it personally yet but Mike Ash says it's good.
