Here are possible solutions to your questions:

  • to center, once you get the touch on an object, select it and move scroll view's contentOffset according to the selected item's position
  • to fade the items, either implement the scrollViewDidScroll: from the UIScrollViewDelegate protocol and watch every item that is off-center, or place semi-transparent (with gradient) images over the edges of the scroll view
