Try this  it works for me if you also need to support ios7  it is based on the transparency of UItoolBar    self navigationController navigationBar setBackgroundImage  UIImage new                                                    forBarMetrics UIBarMetricsDefault       self navigationController navigationBar shadowImage    UIImage new       self navigationController navigationBar translucent   YES      self navigationController view backgroundColor    UIColor clearColor       UIToolbar  blurredView     UIToolbar alloc  initWithFrame self navigationController navigationBar bounds        blurredView setBarStyle UIBarStyleBlack        blurredView setBarTintColor  UIColor redColor         self navigationController navigationBar insertSubview blurredView atIndex 0

If you want to be able to do this programmatically in swift 4 while staying on the same view   if change           navigationController  navigationBar isTranslucent   false         self navigationController  navigationBar backgroundColor   UIColor displayP3Red  255 255  green  206 255  blue  24 255  alpha  1          navigationController  navigationBar barTintColor   UIColor displayP3Red  255 255  green  206 255  blue  24 255  alpha  1        else           navigationController  navigationBar isTranslucent   true         navigationController  navigationBar setBackgroundImage backgroundImage  for   default          navigationController  navigationBar backgroundColor    clear         navigationController  navigationBar barTintColor    clear         One important thing to remember though is to click this button in your storyboard  I had an issue with a jumping display for a long time  Make sureyou set this    Then when you change the translucency of the navigation bar it will not cause the views to jump as the views extend all the way to the top  regardless of the visiblity of the navigation bar

Set the background property of your navigationBar  e g   navigationController  navigationBar backgroundColor   UIColor red  1 0  green  0 0  blue  0 0  alpha  0 5     You may have to change that a bit if you don t have a navigation controller  but that should give you an idea of what to do    Also make sure that the view below actually extends under the bar
