title: White Color to RGB not correct
body: <p>Check out the code </p>
  
  <pre><code>const CGFloat *c = CGColorGetComponents([[UIColor whiteColor] CGColor]); 
  slider1.value = c[0];
  slider2.value = c[1];
  slider3.value = c[2];
  </code></pre>
  
  <p>c[2] is getting 0. For whiteColor all RGB values shld be 1.0. Why its not returning correct value for the blue component?</p>
  
  <p>Any code snippet? for getting RGB values from white color?</p>
