注意：您的storyBoard布局应该看起来像下面的图像..

第2步：在FirstTabBarController中实现以下代码。

   override func viewDidLoad() {
    super.viewDidLoad()

    // Apply transparency to NavigationBar.
    navigationController?.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
    navigationController?.navigationBar.shadowImage = UIImage()

    //Setting up scanView background
    let barView = UIView(frame: CGRect(x:0, y:0, width:view.frame.width,height: (navigationController?.navigationBar.frame.height)! + UIApplication.shared.statusBarFrame.height)) 
    barView.backgroundColor=UIColor.green // set any colour you want..
    barView.layer.borderColor = UIColor.black.cgColor
    barView.layer.borderWidth = 3
    navigationController?.navigationBar.addSubview(barView)

   //Setting up labelView
    let label = UILabel()
    label.frame = CGRect(x:25, y:5, width:view.frame.width - 50 , height:((navigationController?.navigationBar.frame.height)! + UIApplication.shared.statusBarFrame.height) - 10)
    label.text = "AMAR LIFE"
    label.textAlignment = .center
    label.textColor = .black
    label.font = UIFont(name: "HelveticaNeue-medium", size: CGFloat(40))
