iOS Card Scrolling with Bounce

[Mark Schonewille]

Hi Chris,

Make a group of all objects on the card, including the objects that are off-screen. Set the rect of the group to the card rect and use a UIScrollView to scroll the group. Look at the iOS release notes for more info. This info still isn't in the regular documentation.
