ios - 从照片库中选取图像

Question

我正在关注这个Apple Tutorial我收到此错误:

Creating an image format with an unknown type is an error

从照片库中选择图像时。

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    photoImageView.image = selectedImage
    dismiss(animated: true, completion: nil)
}

试试这个...我就是这样做的。

 class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    @IBOutlet weak var photoImageView: UIImageView!
    var standardImg: UIImage!
    var imagePicker: UIImagePickerController!

    override func viewDidLoad() {
        super.viewDidLoad()


    }

    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
        if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
            standardImg = image
            photoImageView.image = standardImg
        }
            imagePicker.dismiss(animated: true, completion: nil)
    }

    @IBAction func addImage(_ sender: UIButton) {

        imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        present(imagePicker, animated: true, completion: nil)
//        sender.setImage(standardImg, for: UIControlState())

    }
}
