iPhone UIImagePickerController didFinishPickingImage:视图控制器之间的UIImage传输？

import UIKit

class ImageViewController: UIViewController {
    @IBOutlet weak var imageView: UIImageView!
    
    var image: UIImage?
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        if let image = image {
            imageView.image = image
        }
    }
}

extension ViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
        if let image = info[.originalImage] as? UIImage {
            let imageViewController = ImageViewController()
            imageViewController.image = image
            navigationController?.pushViewController(imageViewController, animated: true)
        }
        picker.dismiss(animated: true, completion: nil)
    }
}
