iOS revealing tableview header image (Parallax eff

Question

I'm trying to set a large image that reveal more as the table view pulled further down,.. I know I'm not making any sense, it's easier to show an example I recorded from netbot.

Please let me know what the proper term for that and I'll update the title. (Update: apparently it's called parallax effect)

I've tried setting UIImageView to self.tableView.backgroundView and add transparent header for the first section. But it doesn't have the same feeling. it reveals from the top of the image instead of center, it's stretched and squashed on iPad portrait and iPhone landscape (I've tried all contentMode).

I also have tried setting UIImageView to the tableView header. Enabling clipsToBounds does show the center part of the image, but I can't get it to reveal more of the image.

An app called My Artists also has this, but theirs don't bounce back. So, any idea how the brilliant devs at Tapbots approach this?

This is weird. I'm pretty sure I've accepted an answer to this question. Anyway, the answer is ZGExpandZoomView
