title: Scrolling animation on UIPickerView
body: <p>I have an iPhone application with a UIPickerView with 6 components that displays numbers from 0 to 9.<br>
  I want to generate an animation that is similar to the slots machines (when each of the component scrolls for a few seconds and after it stops it display a random number)</p>
  
  <p>Does anyone knows how to create this kind of animation?</p>
  
  <p>Thanks.</p>
