swift - 创建未知类型的图像格式时出错

Question

在 iOS 10 中从图像选择器中选择图像时，我收到错误 - 创建未知类型的图像格式是错误

这是我的代码:

func CamaraInit(){

    let isOk = UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)

    if isOk {

        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self
        imagePicker.sourceType = UIImagePickerControllerSourceType.camera
        imagePicker.cameraDevice = .rear
        imagePicker.showsCameraControls = true
        imagePicker.allowsEditing = true
        imagePicker.cameraCaptureMode = .photo
        // imagePicker.cameraCaptureMode = .video
        self.present(imagePicker, animated: true, completion: nil)
    }

}
func imageInit(){

    let isOk = UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary)

    if isOk {

        let imagePicker = UIImagePickerController()
        imagePicker.delegate = self

        //imagePicker.allowsEditing = true

        self.present(imagePicker, animated: true, completion: nil)
    }

}

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

    var useImage : UIImage!

    let originalImage = info[UIImagePickerControllerOriginalImage] as! UIImage

    let editedImage = info[UIImagePickerControllerEditedImage] as? UIImage

    if editedImage == nil {
        useImage = originalImage
    } else {
        useImage = editedImage
    }

    if picker.sourceType == UIImagePickerControllerSourceType.camera {
        UIImageWriteToSavedPhotosAlbum(useImage, nil, nil, nil)
    }

    self.UIPhotoImage = useImage

    self.viewChange()

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

查了很多资料还是不明白为什么。

似乎这是一种警告而不是错误，至少在我的情况下......上传图像后，viewWillApear 将再次自动调用。这就是您认为图像未上传的原因。
