Getting rid of 1px shadow on a UINavigationBar with a custom background image

Question

I am creating a custom UINavigationBarwith the image of the top bar with a black gradient. How can I kill this 1px shadow border below?

I tried the code that I found here, but it didn’t work on my device, just a simulator. Here is the code I tried.

override func viewDidLoad() {
    super.viewDidLoad()
    UIApplication.sharedApplication().setStatusBarStyle(.LightContent, animated: false)
    self.navigationController?.navigationBar.setBackgroundImage(UIImage(named:"TripNavigationBar2.png"), forBarPosition: .Any, barMetrics: .Default)
    self.navigationController?.navigationBar.shadowImage = UIImage()
}

The insert viewDidAppear:didn't work either.

Can someone explain why and how I can fix this?
