试试这个：

    let backButton = UIButton(type: .system)
    backButton.frame = CGRect(x: 0, y: 0, width: 500, height: 30)
    backButton.setImage(buttonImg, for: .normal)
    backButton.setTitle(title, for: .normal)
    backButton.addTarget(self, action: #selector(self.popVC(_:)), for: .touchUpInside)
    backButton.sizeToFit()
    let backBarButton = UIBarButtonItem(customView: backButton)
    self.navigationItem.leftBarButtonItem = backBarButton
