Re: [MacRuby-devel] Mixing Objective-C and Ruby classes
by victor jalencas 22 May '09

Many thanks John and Laurent. After reading your messages I came back to XCode and discovered I had made a typo in the ObjC part of the code (which, curiously, compiled) and that's why my ruby code didn't find my selector. As for calling ruby code from the obj-c side, I agree it's a bit convoluted (not to mention deprecated). I hope there's a better way to do that in store for upcoming versions. If I understood well your example, you first created the Obj-C subclass and later, dynamically, set its parent to be the ruby class. Anyway, seeing that the norm in Cocoa is delegation rather than extension, and if all ruby classes are readily available in Obj-C, I think I'll manage with just calling ruby code instead of extending it. Apparently I lacked only calling the sharedRuntime method, will need to experiment a bit more when I get back to my Mac. cheers, Victor -- -- Victor Jalencas <victor(a)carotena.net>
