swift - 添加了隐私 key ，但在关闭 UIImagePickerController 时仍然崩溃

Question

发疯了。

使用UIImagePickerController拍照， 呈现 pickerController 后，控制台打印 [MC] systemgroup.com.apple.configurationprofiles 路径的系统组容器为/private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles 和 [MC] 读取自公共(public)有效用户设置。

应用程序在关闭 pickerController 1-2 秒后崩溃。 控制台显示 -[AVCaptureSession release]: message sent to deallocated instance 0x1c4201080

已添加隐私 key :

及相关代码示例:

 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)
}

我是否遗漏了一些其他重要的配置？ 也许与GPUImage相关？

非常感谢任何帮助。

PS。即使我不拍照直接取消也会崩溃。 photoLibrary 类型工作正常。

请处理相机不可用的情况。请使用下面的代码

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)")
        }
    }
}
