Neither is appropriate in my situation: Only one touch-up is needed so converting entire file (even just one method since it is extremely long) to MRR is is inappropriate and I need portability to GNUstep so CoreFoundation (and quite portion of Foundation) have to be avoided. First part of the situation ruled out messages and second part ruled out CF* functions.
OS X built Foundation on top of CoreFoundation but GNUstep built their CoreFoundation side by side with Foundation, so CoreFoundation cannot be assumed to be exist (and in most cases, it doesn't) On Oct 24, 2013, at 18:04, Greg Parker <gpar...@apple.com> wrote: > On Oct 23, 2013, at 10:57 PM, Maxthon Chan <xcvi...@me.com> wrote: >> Situation: I am writing a custom decoder that decodes objects from >> JSON-based archives.
