swift:添加具有相同高度的UITextField的uistackView

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let stackView = UIStackView()
        stackView.axis = .vertical
        stackView.alignment = .fill
        stackView.distribution = .fillEqually
        stackView.spacing = 10
        
        let textField1 = UITextField()
        textField1.borderStyle = .roundedRect
        stackView.addArrangedSubview(textField1)
        
        let textField2 = UITextField()
        textField2.borderStyle = .roundedRect
        stackView.addArrangedSubview(textField2)
        
        let textField3 = UITextField()
        textField3.borderStyle = .roundedRect
        stackView.addArrangedSubview(textField3)
        
        view.addSubview(stackView)
        
        stackView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            stackView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 20),
            stackView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -20),
            stackView.topAnchor.constraint(equalTo: view.topAnchor, constant: 20)
        ])
    }
}
