title: about showing continuous slider value in UISlider
body: <p>Here's what I want to do with UI Slider ....</p>
  
  <p>I have a bunch of files with times and I show them based on slider value. The problem is I want to show the slider value when the user is changing/moving the slider. In other words, the value should change (and be shown on the screen) as the user is moving the slider (and not afterwards).</p>
  
  <p>Can anyone please give me any idea how to do it ? </p>
  
  <p>Thanks.</p>
