  在设置的 viewDidLoad 内，您可以使用它来更改 Headers

  let backButton = UIBarButtonItem()
  backButton.title = "" //in your case it will be empty or you can put the title of your choice
  self.navigationController?.navigationBar.topItem?.backBarButtonItem = backButton
  

  这就是设置你自己的形象

  let backImage = UIImage(named: "backButton")
  self.navigationController?.navigationBar.backIndicatorImage = backImage
  self.navigationController?.navigationBar.backIndicatorTransitionMaskImage = backImage

  您可以像这样实现UINavigationControllerDelegate：

  func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
          let item = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
          viewController.navigationItem.backBarButtonItem = item
      }
  

  它影响下一个推送控制器 backBarButtonItem Headers .

  你的 ViewController edit:

  class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource,UINavigationControllerDelegate  {
  
      override func viewDidLoad() {
          super.viewDidLoad()
          self.navigationController?.delegate = self
      }
