title: iOS: Can't change navigation bar color
body: <p>Can't change navigation bar background color. I've tried setting colors to navigationController?.navigationBar.backgroundColor and navigationController?.navigationBar.barTintColor, such as UIColor.red in the following example, but a white UIImage appears above the navigation bar color in the view hierarchy, as shown in this image: <a href="https://imguh.com/image/CBXaj" rel="nofollow noreferrer">https://imguh.com/image/CBXaj</a></p>
  <p>Also tried making navigation bar translucent and opaque, to no effect. I can change the button colors and customize other elements, but not change the background color of the bar. Appreciate any help.</p>
