UITableViewController - image background

Question

i have UITableViewController, and I'm trying to set a image background. the issue is the background image does not fit the whole screen, in other words, the image background does not stretch with the table cells. this my code

    let imgView =  UIImageView(frame: self.tableView.frame)
    let img = UIImage(named: "b2")
    imgView.image = img
    imgView.frame = CGRectMake(0, 0, self.tableView.frame.width, self.tableView.frame.height)
    imgView.contentMode = UIViewContentMode.ScaleAspectFill
    self.tableView.addSubview(imgView)
    self.tableView.sendSubviewToBack(imgView)

Answer 1

Try with this code:

 tableView.backgroundView = UIImageView(image: UIImage(named: "640x1136.png"))

Add this code in ViewDidLoad
