ios – Is there a strategy to robotically set subview peak of UIAlertController?

I created a stackView which incorporates two UILabels, then add this view to UIAlertController.view by perform addSubview(), for insteading of uialertcontroller’s title and message by particular types. now i can’t get Label’s or view’s peak to set buyer view’s peak and uilaertcontroler’s peak, now i set their peak with a set worth， however i need to understand robotically calculate the sum of peak of two labels and set the peak of subview and uialertcontroller’s peak. end it?

enter picture description right here

the next is my codes, the view’s peak is 300, and uialertcontroller’s peak is 400, make them calculated by tow of labels actual peak ?

let alertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)
        let selectAction = UIAlertAction(title: "Choose", fashion: .default) { (motion) in
            print("choice")
        }

        let cancelAction = UIAlertAction(title: "Cancel", fashion: .cancel, handler: nil)
        alertController.addAction(selectAction)
        alertController.addAction(cancelAction)
        
        let customView = Popover.initCustomizedView(uiViewController: alertController)
       
            alertController.view.addSubview(customView)
            customView.translatesAutoresizingMaskIntoConstraints = false
            customView.topAnchor.constraint(equalTo: alertController.view.topAnchor, fixed: 10).isActive = true
            customView.rightAnchor.constraint(equalTo: alertController.view.rightAnchor, fixed: -10).isActive = true
            customView.leftAnchor.constraint(equalTo: alertController.view.leftAnchor, fixed: 10).isActive = true
            customView.heightAnchor.constraint(equalToConstant: **300**).isActive = true

            alertController.view.translatesAutoresizingMaskIntoConstraints = false
            alertController.view.heightAnchor.constraint(equalToConstant: **400**).isActive = true

            customView.backgroundColor = .inexperienced

           
        showAlert(actionSheetAlertController: alertController)

this perform to create a custom-made view

static func initCustomizedView(uiViewController: UIAlertController) -> UIView{
        // 创建自定义视图
        
        
        // 创建标题标签
        let titleLabel = UILabel()
        titleLabel.translatesAutoresizingMaskIntoConstraints = false
        titleLabel.textual content = "Customized Title bbbbbbbbbbb"
        //titleLabel.textual content = "Customized Title"
        titleLabel.font = UIFont.boldSystemFont(ofSize: 40)
        titleLabel.textColor = .brown
        titleLabel.textAlignment = .middle
        titleLabel.numberOfLines = 0 // 允许多行
        
        
        // 创建消息标签
        let messageLabel = UILabel()
        messageLabel.translatesAutoresizingMaskIntoConstraints = false
        messageLabel.textual content = "Customized Message bbbbbbbbbbbbbbbbbbbb cccccccccccccccccccccccccccccc"
        //messageLabel.textual content = "Customized Message"
        messageLabel.font = UIFont.systemFont(ofSize: 30)
        messageLabel.textColor = .yellow
        messageLabel.textAlignment = .proper
        messageLabel.numberOfLines = 0 // 允许多行
        
        // 将标签添加到自定义视图
        let margin:CGFloat = 10.0
  
        let stackView = UIStackView(arrangedSubviews: [titleLabel, messageLabel])
        stackView.axis = .vertical
        stackView.spacing = 10 // Add spacing between labels
        stackView.alignment = .fill
        stackView.distribution = .equalSpacing

        let containerView = UIView()
        containerView.addSubview(stackView)
        
        
        stackView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            stackView.leadingAnchor.constraint(equalTo: containerView.leadingAnchor),
            stackView.trailingAnchor.constraint(equalTo: containerView.trailingAnchor),
            stackView.topAnchor.constraint(equalTo: containerView.topAnchor),
            stackView.bottomAnchor.constraint(equalTo: containerView.bottomAnchor)
        ])
        
        containerView.layoutIfNeeded()
        containerView.backgroundColor = .inexperienced
        
        return containerView
