title: Is there function to convert UIColor to Hue Saturation Brightness?
body: <p>i can set uicolor with RGB values:</p>
  
  <pre><code>[UIColor colorWithRed:0.53 green:0.37 blue:0.11 alpha:1.00];
  </code></pre>
  
  <p>i can set uicolor with hsb values:</p>
  
  <pre><code>[UIColor colorWithHue:0.10 saturation:0.16 brightness:0.13 alpha:1.00];
  </code></pre>
  
  <p>i also could convert it back to RGB:</p>
  
  <pre><code>CGFloat* colors = CGColorGetComponents(Color1.CGColor);
  </code></pre>
  
  <p>But how i can get HSB from uicolor? </p>
