I ordered a copy of Core Animation for OS X about a week ago. I ordered both the PDF and print book version (which should arrive when it’s actually published). I must say, I really like the Beta Book program from the Pragmatic Programmers guys.
Anyway, I finished reading the book just before leaving for Seattle and I must say, I quite enjoyed it. It’s well written and everything seems to have made sense. There are really good introductions to transitions and keyframe animations in there. If you’re interested in doing any work with Core Animation and are looking for a good introduction you might want to pick this one up.
Hopefully I’ll be able to leverage off of Core Animation for OS X to start doing some cool Core Animation work. We’ll see how it goes.
