not openframeworks related, but great summary of info regarding generic iphone/objc issues
Thanks memo! Great resource. I just wish I had read that before I went and learned all that stuff the long way 
Either way, I’m having fun learning. The iPhone SDK (and objective-c in general) is a little weird when you come from Java/C++, but it’s actually kind of fun when you get the hang of it. Interface Builder is also a blast when you figure out how easy it is. Thanks again for posting.
