I've got a library file (.a). How can I go backwards from this to get some pseudo source code?

Question

Specifically, I'd just like to check out what API calls are made by the library, and a few of the static strings that are in there too.

Is this doable, and what some basic steps I can take to get started? The library is for a universal iOS app.

Answer 1

The strings unix command could help you get the static strings.

To get some general info on libraries linked (and a lot more), use otool

eg otool -tV <library.a> could get you started, if you know what you're looking for grepping in there might be helpful.

If you want to get something resembling 'readable' code though, you'll need to decompile/disassemble the library (which might not be permitted). I'm sure tools could be found to help you with that.
