How to put an image in the center of navigationBar of a UIViewController?

Question

I have this snippet of code used in viewDidLoad of a UIViewController. I\'va no errors. Images exists. I get the background but not the image. Image is a sort of logo.

Answer 1

func centeredNavBarImage (){
    let navcontroller = navigationController!
    let image = #imageLiteral(resourceName: "yourImage")
    let imageView = UIImageView(image:image)

    let bannerWidth = navcontroller.navigationItem.accessibilityFrame.size.width
    let bannerHeight = navcontroller.navigationBar.frame.size.height


    let bannerX = bannerWidth / 2 - image.size.width / 2
    let bannerY = bannerHeight / 2 - image.size.height / 2

    imageView.frame = CGRect(x: bannerX, y: bannerY, width: bannerWidth, height: bannerHeight)
    imageView.contentMode = .scaleAspectFit

    navigationItem.titleView = imageView

}

This is a modified code from https://youtu.be/bLkuu_fmlsU

The bannerWidth takes into account a refresh button item I have on the right side of the navbar. Seems to work.

Run the function on ViewDidLoad
