title: How can I get a slot machine effect in the IOS SDK with text?
body: <p>I need to create a list of words then have the words cycle through in a slot machine effect when swiped from top to bottom.</p>
  
  <p>the only issues I'm having problems figuring out is the scrolling text part. UIPICKERVIEW doesn't cycle around (plus I need to only show one option at a time). I've hunted for examples and/or tutorials regarding this but haven't found anything that points me in the right direct. </p>
  
  <p>Anyone know of a tutorial or have suggestions where I can get started or further my research? thanks.</p>
