I know this is a little late for a follow up, but I've looked for a library to do this, as well, but haven't found one.

I was able to do this using the new UIViewController Transitioning API. This example should get you started:

To augment this example to get the pinch/pull table view cell separation animation you would need to identify the table view cell that was selected (or "selected" relative to the pinch gesture"), then in -animateTransition: you would animate the cells above and below the selected cell out of view, revealing your details view controller.
