title: UISlider, slide to unlock
body: <p>I need to add an UISlider control in my iphone application. That should look like the "Slide to unlock" slider which is displayed in any iphone or ipod touch. I am unable to figure out how to do this.</p>
  
  <p>In slide to unlock slider, if we leave the thumbImage in the middle of the slider it comes back to the left side automatically. How do we get this kind of functionality working in our project.</p>
