  <p>I looked around the web but I haven't found a clear example. I have no experience with CGGradient but I need a very simple thing:
  I want add a gradient to the NavigationBar of my NavigationController, the gradient should be linear, from top to bottom. I want the start color to be : (88.0, 38.0, 40.0) and the end color (50.0 15.0 16.0). Could you please give me an example of how I could add this gradient to my navigation bar?</p>
  
  <p>Thank you    </p>
