objective c - Screen capture video in iOS programmatically

I'm trying to create a UIView that allows a user to tap a button in i and record the screen (not make a video from the camera), then save it to the document folder. I've seen a couple of SO articles here that talk about AVAssetWriter and make references to this link: http://codethink.no-ip.org/wordpress/archives/673 , but that link appears to be dead.

But no one has actually shown a solution or provided any examples on how to accomplish. Anyone have any ideas or can point me in the right direction? This should be simpler than it is.

Thanks, Doug

The link is not dead.

If you check the comments, there is also some code that will mix audio & video and save it as a quicktime movie.

If you still can't access the link, there is a guy selling the same code on binpress:
