如何创建UIButton以显示与UIBarButtonItem相同的效果？

let customButton = UIButton(type: .system)

customButton.setTitle("Button Title", for: .normal)
customButton.titleLabel?.font = UIFont.systemFont(ofSize: 17)

customButton.backgroundColor = UIColor.clear
customButton.layer.borderWidth = 1
customButton.layer.borderColor = UIColor.lightGray.cgColor

customButton.contentEdgeInsets = UIEdgeInsets(top: 8, left: 16, bottom: 8, right: 16)

customButton.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)

@objc func buttonTapped() {
    print("Custom UIButton tapped")
}

view.addSubview(customButton)

customButton.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    customButton.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 16),
    customButton.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -16)
])
