Swift: Make the background image of UITableViewController embedded in Navigation Controller fill the entire screen

Question

I managed to create translucent and rounded UITableViewCells in a UITableViewController that is embedded inside a Navigation Controller with this line of code in viewDidLoad():

    tableView.backgroundView = UIImageView(image: UIImage(named: "nightTokyo"))

But I want the background image to fill the entire phone screen. I changed the code (and only this line of code) to:

    navigationController?.view = UIImageView(image: UIImage(named: "nightTokyo"))

Now the background image fills up the entire phone screen, but my table and even the iPhone's time and battery indicator icons are missing.

What I want is for the background image to fill the entire screen, but the tableView, its cells, the iPhone time, battery level icon, etc. to remain displayed.

Answer 1

navigationController?.setNavigationBarHidden(true, animated: true)
