從照片庫

Question

採摘像我跟隨此Apple Tutorial，我得到這個錯誤：

Creating an image format with an unknown type is an error

，同時從圖片庫中選擇圖像。

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

Answer 1

試試這個......我是這樣做的。

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()) 

    } 
} 

Answer 2

解是

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) 
{ 

    if let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage { 
     photoImageView.image = selectedImage 
    } 
    else{ 
     print("Picking image is not in correct format") 
    } 

    self.dismiss(animated: true, completion: nil) 
}
