如何在UIView中居中放置多个元素

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let containerView = UIView(frame: CGRect(x: 0, y: 0, width: 200, height: 100))
        containerView.backgroundColor = UIColor.lightGray
        view.addSubview(containerView)
        
        let label1 = UILabel(frame: CGRect(x: 0, y: 0, width: 80, height: 30))
        label1.text = "Label 1"
        label1.textAlignment = .center
        containerView.addSubview(label1)
        
        let label2 = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 30))
        label2.text = "Label 2"
        label2.textAlignment = .center
        containerView.addSubview(label2)
        
        let totalWidth = label1.frame.width + label2.frame.width
        let x = (containerView.frame.width - totalWidth) / 2
        
        label1.frame.origin.x = x
        label2.frame.origin.x = x + label1.frame.width
