Returning an autorelease'd CFTypeRef with ARC
I am new to Automatic Reference Counting with LLVM and Objective-C, and have a question about returning CGImageRefs from my Objective-C function. In the days of manual reference counting, it was possible to simply cast the CGImageRef to an id, autorelease it, then return the original CGImageRef. With ARC, I am aware that you can direct the ARC system to autorelease and return your retainable objec

How to Autorelease a CGImageRef?
I have a method that returns a CGImageRef object. It contains this call: CGImageRef posterFrame = [avAssetImage copyCGImageAtTime:time actualTime:nil error:&error]; ... return posterFrame; This situation, as I understand it, calls for an autorelease. But I have no idea how to do it. I've tried using CFCollectable(), but it doesn't work. Any ideas?

Parallax Scrolling (Core Animation Games 4)
It has been quite a while since I wrote the last article in the Core Animation Games series. If you rem ember, in it I complained bitterly about the CA scrolling classes, and how none of them filled the ticket. To recapitulate, these are the 3 things I needed: A window into a coordinate system plane populated by â€œobjectsâ€â€¦ that smoothly moves through it by remapping how its borders map to that unde
