Swift custom back button in navigation bar

Question

I am trying to use a custom image for my back button in the navigation bar. I am using the below code, which adds the image, but also keeps the text "Back" in the button. I want to also remove the text. Can I do that?

self.navigationController?.navigationBar.backIndicatorImage = UIImage(named: "icon-back")
self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "icon-back")
self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: nil, action: nil)

Answer 1

Try code below :-)

func SetBackBarButtonCustom()
{
    //Back buttion
    let btnLeftMenu: UIButton = UIButton()
    btnLeftMenu.setImage(UIImage(named: "back_arrow"), for: UIControlState())
    btnLeftMenu.addTarget(self, action: #selector(UIViewController.onClcikBack), for: UIControlEvents.touchUpInside)
    btnLeftMenu.frame = CGRect(x: 0, y: 0, width: 33/2, height: 27/2)
    let barButton = UIBarButtonItem(customView: btnLeftMenu)
    self.navigationItem.leftBarButtonItem = barButton
}

func onClcikBack()
{
    _ = self.navigationController?.popViewController(animated: true)
}
