title: How to imitate apple's stock timer app's UIPickerView?
body: <p>I want my components to wrap around the wheel,
  not allow a value of zero (across all components), and
  display units statically in each component. </p>
  
  <p>Basically the functionality of the minutes component in the UPickerView of the Timer in the Clock app on every iPhone.</p>
  
  <p>ATM I want to know if it's possible to do the wrap around since I have had no luck finding examples online for multiple components.</p>
  
  <p>Thanks in advance.</p>
