How to implement iPhone Contact app edit transition effect?

I'd like to reproduce the animation 开发者_如何学Pythoneffect that the Contact app uses when switching to edit mode. Specifically I have a number of fields that I'd like to display in a more friendly format, but then expand them into a layout that makes them easier to update or add when in edit mode.

Is this done using core animation?

Thanks

No animation is needed. Just monitor when the table view's editing property changes (when the Edit button is pressed). Then add code to your delegate methods to compose, draw and indent cells in a different way, when the table view is in editing mode.
