Swift :-如何在Swift的UIScrollview中向UIImageview添加偏移量？

import UIKit

class ViewController: UIViewController, UIScrollViewDelegate {
    var scrollView: UIScrollView!
    var imageView: UIImageView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建UIScrollView实例
        scrollView = UIScrollView(frame: view.bounds)
        scrollView.delegate = self
        scrollView.contentSize = CGSize(width: 2 * view.bounds.width, height: view.bounds.height)
        view.addSubview(scrollView)
        
        // 创建UIImageView实例
        imageView = UIImageView(image: UIImage(named: "image"))
        imageView.frame = CGRect(x: 0, y: 0, width: view.bounds.width, height: view.bounds.height)
        scrollView.addSubview(imageView)
        
        // 设置UIScrollView的属性
        scrollView.isPagingEnabled = true
        scrollView.showsHorizontalScrollIndicator = false
        scrollView.showsVerticalScrollIndicator = false
        
        // 设置UIScrollView的contentOffset初始值
        scrollView.contentOffset = CGPoint(x: view.bounds.width, y: 0)
    }
    
    // UIScrollViewDelegate代理方法
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        let offsetX = scrollView.contentOffset.x
        
        // 根据偏移量调整UIImageView的frame
        imageView.frame = CGRect(x: offsetX, y: 0, width: view.bounds.width, height: view.bounds.height)
    }
}
