Ok. This is interesting. I wrote a little code to see what might be going on. Whatever was true when the AppKit release notes were published has either changed or the term "supported" has a loose definition. Thanks for pointing that out, Mike, but I don't think it's accurate or I've misun

Re: How do I get a CGContextRef?

well where are you calling it? That's the correct function, but only works when there is a graphics context set, and that's only inside drawRect: in a UIView. I wandered through the documentation a little and got reasonably lost, it does talk about NSGraphicsContext in there, but remember a

Facile Core Data Question

How to I cause a managed object to perform a certain action upon deletion? If I were working with Ruby On Rails or some other ORMs, I'd be able to define an on_delete method or action that would automatically be invoked. In core data, it seems that the best thing to do is to have a godlik
