title: How to change a UISlider value using a single touch?
body: <p>I'm developing my first iOS app which contains a <code>UISlider</code>. I know how to get the value when the <code>UISlider</code> is dragged. But for my app I need to get the slider's value in a single touch; i.e. if I touch somewhere in the <code>UISlider</code>, a <code>UILabel</code> should display its correct value. </p>
  
  <p>Is it possible to this way. Any tutorial or code will very helpful. </p>
