title: Change blurring effect of UINavigationBar
body: <p>I need to implement a <code>UINavigationBar</code> with a custom design, the back image needs to be changed, all the colors need to be changed and the height needs to be changed.</p>
  
  <p>I know all that is possible, but I also need to change the blur effect. It needs to be a lighter blur. Is there a way of doing this without going into private APIs?</p>
  
  <p>Edit: a picture of what it is supposed to look like (I know the status bar is pixelated, ignore it):</p>
