如何在UIalertController中添加图片作为标题？

let alertController = UIAlertController(title: "", message: nil, preferredStyle: .alert)

// 创建UIImageView对象并添加到UIAlertController中
let imageView = UIImageView(image: UIImage(named: "your_image_name"))
imageView.translatesAutoresizingMaskIntoConstraints = false
alertController.view.addSubview(imageView)

// 设置UIImageView的约束
imageView.centerXAnchor.constraint(equalTo: alertController.view.centerXAnchor).isActive = true
imageView.topAnchor.constraint(equalTo: alertController.view.topAnchor, constant: 20).isActive = true

// 创建UILabel对象并添加到UIAlertController中
let titleLabel = UILabel()
titleLabel.text = "Your Title"
titleLabel.font = UIFont.boldSystemFont(ofSize: 17)
titleLabel.textAlignment = .center
titleLabel.translatesAutoresizingMaskIntoConstraints = false
alertController.view.addSubview(titleLabel)

// 设置UILabel的约束
titleLabel.centerXAnchor.constraint(equalTo: alertController.view.centerXAnchor).isActive = true
titleLabel.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 8).isActive = true

// 创建并添加其他UIAlertAction按钮（如取消、确定等）

// 显示UIAlertController
present(alertController, animated: true, completion: nil)
