UINavigationController NavigationBar not applying transparent image - swift

Question

When applying transparent image in the navigation tab bar. It's turning white instead of being transparent..
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.tintColor = UIColor.white

Answer 1

Ensure that something is under the navigation bar so that it does not just become transparent showing the white background. You will need to drag uiviews under it and then add layout constraints. Otherwise, make sure you check that you have not changed the color of the navigation bar elsewhere.

Answer 2

Use this extension to make navigation bar transperant.
extension UINavigationController {
func transparant() {
self.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.isTranslucent = true
self.view.backgroundColor = UIColor.clear
}
}

Answer 3

if you are using Navigation Controller try this:
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
title = "Some Title"
if you are using UINavigationBar try this:
#IBOutlet var navBarOutlet: UINavigationBar!
override func viewDidLoad() {
super.viewDidLoad()
// navigatin bar transparent
navBarOutlet.setBackgroundImage(UIImage(),for:.default)
navBarOutlet.shadowImage=UIImage()
navBarOutlet.topItem?.title = "Some Title"
}
