setting titleView of custom UINavigationBar

Question

I have a custom navigation bar that doesn't really do any navigation controlling (app only has one view) its instead used as a header to display the logo against a solid background colour. So I put a navigation bar onto the main view controller and created an outlet so I can reference it in the code. (Using swift by the way).

Right now I'm struggling with setting the logo image in the center of the nav bar. I need to do this with the titleView (instead of setting an entire background image). So far what I've read says to use self.navigationItem.titleView in the view controller, but I think that only works when using a UINavigationController. Here is my code so far:

@IBOutlet weak var navBar: UINavigationBar!

override func viewDidLoad() {
    super.viewDidLoad()

    let logoImage = UIImageView(frame: CGRect(x:0, y:0, width: 200, height: 45))
    logoImage.contentMode = .ScaleAspectFit

    let logo = UIImage(named: "logo.png")
    logoImage.image = logo
    self.navigationItem.titleView = logoImage
}

But this doesn't work. How do I get access to the titleView using a custom UINavigationBar like this?

Answer 1

You need to access UINavigationBar's topItem attribute. Then you can set the topItem's titleView with a UIImageView.

So in your case:

self.navBar.topItem?.titleView = logoImage
