iPhone:创建自定义UIBarButton,按下时颜色不同？

let customButton = UIButton(type: .system)
customButton.setImage(UIImage(named: "your_image_name"), for: .normal)
customButton.setImage(UIImage(named: "your_image_name_highlighted"), for: .highlighted)
customButton.addTarget(self, action: #selector(customButtonTapped), for: .touchUpInside)

let customBarButtonItem = UIBarButtonItem(customView: customButton)

customButton.setTitleColor(UIColor.blue, for: .normal)
customButton.setTitleColor(UIColor.red, for: .highlighted)

self.navigationItem.rightBarButtonItem = customBarButtonItem

@objc func customButtonTapped() {
    // 按钮点击事件的处理逻辑
}
