添加了隐私密钥，但是在关闭UIImagePickerController时仍然崩溃

Question

发疯。

使用 UIImagePickerController 拍照， 呈现pickerController之后，cosole打印 [MC] systemgroup.com.apple.configurationprofiles路径的系统组容器是/private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles 和 [MC]公开的有效用户设置。

在关闭pickerController 1-2秒后，应用程序崩溃。 并且控制台显示-[AVCaptureSession版本]：发送到已释放实例0x1c4201080

的消息

已添加隐私密钥：

和相关代码示例：

 func seletedImage()  {

    let alertAction = UIAlertController.init(title: nil, message: nil, preferredStyle: .actionSheet)
    alertAction.addAction(UIAlertAction.init(title: "拍照", style: .default, handler: { [weak self] (alertCamera) in
        self?.showImagePicker(sourceType: .camera)
    }))
    alertAction.addAction(UIAlertAction.init(title: "从相册中选择", style:.default, handler: { [weak self] (alertPhpto) in
        self?.showImagePicker(sourceType: .photoLibrary)
    }))
    alertAction.addAction(UIAlertAction.init(title: "取消", style: .cancel, handler: nil))

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

 func showImagePicker(sourceType: UIImagePickerControllerSourceType) {

    if UIImagePickerController.isSourceTypeAvailable(sourceType) == false {
        if sourceType == .camera { print("未授予使用相机权限") }
        if sourceType == .photoLibrary { print("未授予访问相册权限") }
        return
    }

    let picker: UIImagePickerController = UIImagePickerController()
    picker.delegate = self as UIImagePickerControllerDelegate & UINavigationControllerDelegate
    picker.sourceType = sourceType
    picker.allowsEditing = false

    weak var weakself = self
    weakself?.present(picker, animated: true, completion: nil)
}

我是否缺少其他一些重要配置？ 也许与 GPUImage 有关？

真的很感谢任何帮助。

PS。即使我不拍照也直接崩溃就崩溃了。 photoLibrary 类型可以正常工作。

请处理相机不可用的情况。请使用以下代码

func  SelectFromCamera()  {

    //Camera
    let cameraMediaType = AVMediaTypeVideo
    AVCaptureDevice.requestAccess(forMediaType: cameraMediaType) { granted in
        if granted {
            print("Granted access to \(cameraMediaType)")
            if UIImagePickerController.isSourceTypeAvailable(
                UIImagePickerControllerSourceType.camera) {
                let imagePicker = UIImagePickerController()
                imagePicker.delegate = self
                imagePicker.sourceType =
                    UIImagePickerControllerSourceType.camera
                imagePicker.mediaTypes = ["public.image"]
                //  imagePicker.allowsEditing = false
                self.present(imagePicker, animated: true,
                             completion: nil)
            }
        } else {
            //open app setting if not authorize to access camera
            print("Denied access to \(cameraMediaType)")
        }
    }
}
