I need to add a few methods to an already identified class in a closed source application. Using f-script anwywhere and gdb I know what I need to interact with to acheive my goals.
However I am struggling to find a solution to allow me to inject some code (preferably objective-c) into the running application.
For the time being I would be quite happy to just inject the code via gdb and manually start the code as I just recently upgraded to Snow leopard and are aware of issues with SIMBL.
Are there any basic guides on getting started with this? I fail to find anything really useful from googling around.
I think I need to create an application bundle (never done this before so this in itself is a challenge) and use GDB to load into the application. Once this is done I beleive I can then call my bundles code from GDB.
Basically I think I need some hints on creating the bundle and the subsequent loading via GDB. Any simple examples of loading a class/object into an application (maybe simply a hello world should suit) would be very much appreciated.
I may also be misguided with the focus on bundles?
Thanks,
