The objective C runtime has lots of goodies for your consumption.
If you want an iVar, you can call object_getInstanceVariable with a string name.
If you want variables, it’s a bit more work, and they have to be globally visible to the linker. You can use CFBundleGetDataPointerForName for that purpose.
Be sure to read the documentation for restrictions and specific information about runtime information, and the availability of stuff on different platforms.
