Swift3 Xcode 8-swift 3:创建具有未知类型的图像格式时出错

使用UIImagePicker选择图像时出错：

[Generic] Creating an image format with an unknown type is an error

我使用的是Xcode 8.1和Swift 3。 我已经在网上搜索过了，但似乎没有什么能解决我的问题，请帮助

这是我的代码：

class TabBarController: UITabBarController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

var isSelected: Bool = false
var imgPicker: UIImagePickerController = UIImagePickerController()

override func viewDidLoad() {
    super.viewDidLoad()
    //imgPicker = UIImagePickerController()
    imgPicker.delegate = self
    imgPicker.allowsEditing = false
    imgPicker.sourceType = .photoLibrary
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    imgPicker.dismiss(animated: true, completion: nil)

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        self.performSegue(withIdentifier: "toPostPicture", sender: image)
    }
}

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

func askImagePickerSource(sender: UIViewController) {
    if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
        let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

        let cameraAction = UIAlertAction(title: "Camera", style: .default, handler: { (action: UIAlertAction) in
            self.imgPicker.sourceType = .camera
            self.imgPicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .camera)!
            sender.present(self.imgPicker, animated: true, completion: nil)
        })
        let photoLibraryAction = UIAlertAction(title: "Photo Library", style: .default, handler: { (action: UIAlertAction) in
            self.imgPicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
            sender.present(self.imgPicker, animated: true, completion: nil)
        })
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (UIAlertAction) in
            sender.dismiss(animated: true, completion: nil)
        }

        alert.addAction(cameraAction)
        alert.addAction(photoLibraryAction)
        alert.addAction(cancelAction)

        sender.present(alert, animated: true, completion: nil)
    } else {
        self.imgPicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
        sender.present(self.imgPicker, animated: true, completion: nil)
    }
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if segue.identifier == "toPostPicture" {
        if let postPictureVC = segue.destination as? PostPictureVC {
            if let image = sender as? UIImage {
                postPictureVC.image = image
            }
        }
    }
}

}

您能否将

info

参数的

.debugDescription

发布到您的选取器代理中

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

我遇到了同样的问题，没有为UIImagePickerController添加作为“self”的委托。添加后，我能够从gallery中获取所选图像。但是，即使将委托添加为self并能够访问图像（显示在ImageView上），我仍然会遇到相同的错误。经过对SO的进一步研究，我知道这只是一个bug，不会以任何方式影响应用程序

另请参见以下信息。debugDescription:[“UIImagePickerController中间类型”：public.image，“UIImagePickerController参考URL”：资产-library://asset/asset.JPG?id=ED7AC36B-A150-4C38-BB8C-B6D696F4F2ED&ext=JPG，“UIImagePickerControllerOriginalImage”：尺寸{3000，2002}方向0比例1.000000]，如果让图像=信息[UIImagePickerControllerEditedImage]为？UIImage{//保存图像}如果让image=info[UIImagePickerControllerOriginalImage]为？UIImage{//保存图像}其他{打印（“出错”）}可能重复的
