Comments on: Fun with the Objective-C Runtime http://jens.ayton.se/blag/fun-with-the-objc-runtime/ Cocoa coding stuff, when I can be bothered.

(Has-a vs. is-a releationships, and all that.)

There are some problems with it and it's not quite complete, but it's good enough that we're actually using it in production :).

Though I think there's a slight mistake in the comment on Easy Dictionary, isn't it -setFruit: which is dynamically generated? I wouldn't be so quick to discount using the code either, I typically prototype things in NSDictionary and use my version of this code to synthesize virtual assessors. So when I swap that dictionary out for a bona fide model object I just have to copy and paste the property declarations and include the synthesize directive. That way client code will work with zero changes, it's as if nothing changed. I look forward to working on 64 bit only when the instance variables are synthesized automatically too.
