import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 加载JPEG图像文件
        guard let imagePath = Bundle.main.path(forResource: "image", ofType: "jpg") else {
            return
        }
        let imageURL = URL(fileURLWithPath: imagePath)
        guard let imageData = try? Data(contentsOf: imageURL) else {
            return
        }
        
        // 创建UIImageView
        let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 200, height: 200))
        imageView.center = view.center
        
        // 设置图像
        if let image = UIImage(data: imageData) {
            imageView.image = image
        }
        
        // 添加到视图
