我可以在UIScrollView (Swift)中实现一个可伸缩的图像标题吗？

import UIKit

class ViewController: UIViewController, UIScrollViewDelegate {
    var scrollView: UIScrollView!
    var imageView: UIImageView!
    var titleLabel: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIScrollView
        scrollView = UIScrollView(frame: view.bounds)
        scrollView.delegate = self
        scrollView.minimumZoomScale = 1.0
        scrollView.maximumZoomScale = 3.0
        view.addSubview(scrollView)
        
        // 创建UIImageView
        imageView = UIImageView(image: UIImage(named: "image"))
        imageView.contentMode = .scaleAspectFit
        scrollView.addSubview(imageView)
        
        // 创建UILabel
        titleLabel = UILabel(frame: CGRect(x: 0, y: 20, width: view.bounds.width, height: 30))
        titleLabel.text = "可伸缩的图像标题"
        titleLabel.textAlignment = .center
        scrollView.addSubview(titleLabel)
        
        // 设置UIScrollView的contentSize
        scrollView.contentSize = CGSize(width: view.bounds.width, height: view.bounds.height + 50)
    }
    
    // UIScrollViewDelegate方法，返回要缩放的视图
    func viewForZooming(in scrollView: UIScrollView) -> UIView? {
        return imageView
    }
    
    // UIScrollViewDelegate方法，缩放时调用
    func scrollViewDidZoom(_ scrollView: UIScrollView) {
        // 根据缩放比例调整标题的大小
        let scale = scrollView.zoomScale
        titleLabel.transform = CGAffineTransform(scaleX: scale, y: scale)
    }
}
