UIImagePickerController 扩展发现失败并出现错误：(null)

我试图在我的 ViewController 上实现一个 ImagePicker，但结果发现它呈现了一个空白的 ImagePicker 控制器并且UIImagePickerController extension discovery failed with error: (null)控制台上的消息。

我不知道我做错了什么，我也没有找到有关此事的信息。不过，我注意到的一件事是 PickerView 的显示时间有点太长了。

ImagePicker相关的代码如下：

private let imagePicker = UIImagePickerController()

private func setupImagePicker() {
        imagePicker.sourceType = .photoLibrary
        imagePicker.allowsEditing = false
        imagePicker.delegate = self
        imagePicker.mediaTypes = ["public.image"]
}

    @objc private func launchImagePicker() {

        let photos = PHPhotoLibrary.authorizationStatus()
        if photos == .notDetermined {
            PHPhotoLibrary.requestAuthorization({ [weak self] status in
                DispatchQueue.main.async {
                    if status == .authorized, let picker = self?.imagePicker {
                        self?.present(picker, animated: true, completion: nil)
                    } else {
                        self?.present(URealtorUtils.getAlert(message: "You have to authorize photo library access in order to upload a photo"), animated: true, completion: nil)
                    }
                }
            })
        } else if photos == .authorized {
            present(imagePicker, animated: true, completion: nil)
        }
    }

extension MyController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    func imagePickerController(_ picker: UIImagePickerController,
                               didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey: Any]) {
        if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
            self.viewModel.setPropertyImage(image)
        }
        dismiss(animated: true, completion: nil)
    }

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

这是当 PickerView 出现时我得到的屏幕截图：

我检查了详细信息，您的实施没有问题。 我还在这里查看了苹果的官方样本。https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller https://developer.apple.com/documentation/uikit/uiimagepickercontroller/customizing_an_image_picker_controller结果一样！

最后，这是与iOS模拟器（版本11.3.1）相关的问题。 仅供参考，我发现 iPhone 11 Pro Max 在某些以前的版本中无法使用，但 iPhone 8 和其他一些版本可以使用。 我只是希望你们不要在这上面浪费时间。前进。

Thanks.
