Extract Objective-C class information from library at runtime

I was wondering if there were a way to extract information from an objective-c app, static or dynamic library and/or framework?

Information such as an array of class names without instantiating or running the target.

I've checked google and the apple developer documentation and haven't foun开发者_JS百科d anything.

F-script appears to be able to do what you want, but I'm no expert. Check out www.fscript.org.

If you want to extract classes from an application/dynamic library, there is a handy tool called ClassDump.

It can even generate the header files in order to get an overview of the classes, protocols, etc.

If you want to do it at runtime, then take a look at the source code to learn how to load and parse the different mach-o segments.

This is an excellent starting point for reverse-engineering Cocoa apps:

It mentions F-Script, class-dump, and a few others.
