How to change the border color below the navigation bar?

Question

Can anyone advise me on how the border below the navigation bar can be changed?

Answer 1

In Swift like the @Legolas answer:

if let navigationController = self.navigationController {

   let navigationBar = navigationController.navigationBar     
   let navBorder: UIView = UIView(frame: CGRectMake(0, navigationBar.frame.size.height - 1, navigationBar.frame.size.width, 1))
   // Set the color you want here
   navBorder.backgroundColor = UIColor(red: 0.19, green: 0.19, blue: 0.2, alpha: 1)
   navBorder.opaque = true
   self.navigationController?.navigationBar.addSubview(navBorder)
}

You can put in the viewDidLoad() of your UIViewController.
