iOS 8 Swift Xcode 6 - Set top nav bar bg color and height

Question

I have looked everywhere and tested all the code snippets posted on Stack, but nothing works for me as I need it to work.

I simply want to set:

• Nav bar hei

Answer 1

Nav bar height:

In a custom navigation controller subclass...

The trick with this one is to NOT change the actual height of the navigation bar and instead adjust its origin.

func viewDidLoad() {
    super.viewDidLoad()

    navigationBar.frame.origin.y = -10 
}

Nav bar bg color in RGB:

In a custom navigation controller subclass...

func viewDidLoad() {
    super.viewDidLoad()

    navigationBar.barTintColor = // YOUR COLOR
}

or use the appearance proxy

UINavigationBar.appearance().barTintColor = // YOUR COLOR

Nav bar centered logo

In a custom view controller...

func viewDidLoad() {
    super.viewDidLoad()

    navigationItem.titleView = UIImageView(image: // YOUR LOGO)
}
