Re: NSImageViews, Block Animation and Frame by Frame Image Swapping
Great. That helps. So can you point me to a technical note with an overview and/or examples of the new block based animations?

Re: NSImageViews, Block Animation and Frame by Frame Image Swapping
Probably a combination of the docs and the WWDC session on UIKit Animations (can't recall the session number off hand). On Sep 15, 2010, at 11:38 AM, James Miller wrote: Great. That helps.
