Question

我收到了这个令人沮丧的错误，并且不知道自

以来我在做什么错

  

制作照片

     

并从库中选择无效

我使用的是Swift 4，我的代码如下：

class ProfileViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

  var imagePicker = UIImagePickerController()

      override func viewDidLoad() {
        super.viewDidLoad()
        imagePicker.delegate = self 
   }

      @objc func changeThePicture(sender: UITapGestureRecognizer) {
    let alertController = UIAlertController(title: nil, message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    alertController.addAction(UIAlertAction(title: "Choose a photo from your gallery", style: UIAlertAction.Style.default, handler: { (action) -> Void in
        self.changePicture()
    }))
    alertController.addAction(UIAlertAction(title: "Make a photo", style: UIAlertAction.Style.default, handler: { (action) -> Void in
        self.openCamera()
    }))

    alertController.addAction(UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel, handler: nil))
    self.present(alertController, animated: true, completion: nil)
}

func changePicture() {
    self.checkPhotoLibraryPermission {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.photoLibrary) {
            self.imagePicker.allowsEditing = false
            self.imagePicker.sourceType = .photoLibrary
            self.imagePicker.mediaTypes = [kUTTypeImage as String]
            self.present(self.imagePicker, animated: true, completion: nil)
        }
    }
}

func openCamera() {
    self.checkMakePhotoPermission {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerController.SourceType.camera) {
            self.imagePicker.allowsEditing = false
            self.imagePicker.sourceType = .camera
            self.imagePicker.mediaTypes = [kUTTypeImage as String]
            self.present(self.imagePicker, animated: true, completion: nil)
        }
    }
}

@IBAction func changePictureButton(_ sender: UITapGestureRecognizer) {
    self.changeThePicture(sender: sender)
}

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    dismiss(animated: true, completion: nil)
}

@objc func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    print("media")
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        self.chosenImage = pickedImage
        userProfilePic.imageView.image = pickedImage
        uploadImage(userImage: chosenImage) { (result) in
        }
    }
    dismiss(animated:true, completion: nil)
}

  

仅当我拍照时才打印媒体...但是当我从图库中选择时什么也没发生，我会收到此错误

     发现扩展名时遇到

[发现]错误：错误   域= PlugInKit代码= 13“查询已取消”   UserInfo = {NSLocalizedDescription =查询已取消}

Answer 1

您的问题是因为您在完全关闭图像选择器模式之前执行逻辑（上传图像）。

将您的方法更改为此：

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    print("media")
    if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
        dismiss(animated:true) { [weak self] in
            self?.chosenImage = pickedImage
            self?.userProfilePic.imageView.image = pickedImage
            self?.uploadImage(userImage: chosenImage) { (result) in
            }
        }
    } else {
        dismiss(animated:true, completion: nil)
    }
}
