title: Handle Multiple UISlider
body: <p>I have 4 UISlider with minimum value 0, Maximum value 10. I have one constant value(Ex:20).</p>
  
  <p>My goal is sum of 4 slider value doesn't go above that constant value. </p>
  
  <p>Ex: if i drag and set to maximum value of 1st and 2nd slider(i.e 10), Now the sum of 4 slider is 20. </p>
  
  <p>I don't want to allow other 2 sliders(3rd,4th) to increase. if i decrease any slider(1st or 2nd) value means then i can allow them(2,3,4) to increase  sliders values. </p>
  
  <p>help me to achieve this.</p>
