Re: Substitute classes

[Gregory Casamento]

Yes, it is possible.  You can use the Objective-C 2.0 runtime to
change the implementations of certain methods in those classes:

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ObjCRuntimeRef/Reference/reference.html#//apple_ref/c/func/method_exchangeImplementations

More things you should be aware of...

What you should be aware of is that GNUstep is LGPL 2.1 or later
licensed software.   While simply linking with GNUstep's libraries
wouldn't cause you to need to release your software under the LGPL,
directly incorporating code from the project would since it would be
considered a "combined work."

Normally, this would be fine (assuming you're okay with releasing your
code), but Apple's terms of service for the App Store place
restrictions on distribution which is not compatible with the LGPL/GPL
license.   While Apple, to my knowledge, has never removed an app
because it was GPL'd or LGPL'd, the members of the VLC project
voluntarily removed their app from the store due to licensing concerns
raised by the FSF.

While I realize this is not the answer you were hoping for, I hope it
helps somewhat.
