title: How can I set the UINavigationbar with gradient color?
body: <p>I want to set the <code>UINavigationbar</code> <code>backgroundColor</code> to a gradient color where I would like to set it via an array of colors to create a Gradient, ideally, as accessible methods inside <code>UINavigationBar</code> to change its color to this gradient.</p>
  
  <p>Any suggestions? (Aside from setting an image manually as the background image of the navigation bar)</p>
