ios - EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000200 向图像添加过滤器时

Question

我正在尝试将图像更改为黑白，这些图像是从服务调用中提供的，一旦获得图像，我就会应用黑色滤镜将它们更改为黑白。我只在 iOS 13 上遇到过这个悬空指针异常，其他 iOS 版本没有这个问题。

这是代码:

extension UIImage {

    var noir: UIImage? {

        let context = CIContext(options: nil)

        guard let currentFilter = CIFilter(name: "CIPhotoEffectNoir") else {
            return nil
        }

        currentFilter.setValue(CIImage(image: self), forKey: kCIInputImageKey)

        if let output = currentFilter.outputImage,
            let cgImage = context.createCGImage(output, from: output.extent) {
            return UIImage(cgImage: cgImage, scale: scale, orientation: imageOrientation)
        }

        return nil
    }
}

用例:

var member: Faculty? {
    didSet {
        guard let lecturer = self.member else {
            return
        }

        FacultyService.image(
            atPath: lecturer.thumbnailPath,
            process: { (image: UIImage) -> UIImage in

                if lecturer.Id != nil {
                    return image.noir!.withRenderingMode(.alwaysOriginal)
                }  else {
                    return image.withRenderingMode(.alwaysOriginal)
                }
        },
            success: { [weak self] (path: String, image: UIImage) -> Void in
                guard let strongSelf = self else { return }

                if path == strongSelf.member?.imagePath {
                    self.imageButton.setImage(image, for: .normal)
                    self.imageButton.layer.animate()
                }
            },
            failure: { () -> Void in

        })
    }
}

检查 Firebase Crashlytics，我注意到 Keys 部分中的以下行:

CoreUI: deallocating _CUIInternalLinkRendition 205 /System/Library/CoreServices/CoreGlyphs.bundle/Assets.car

这很可能是编译器或 Core Image 框架的错误。

我鼓励您在 Feedback Assistant 上提交错误报告.

如果你看this thread从 Apple 论坛中，以前有过类似的问题，您可能只需要等待 Apple 解决它...

还有其他人遇到了您的特定错误消息，How to fix warning "CoreUI: RunTimeThemeRefForBundleIdentifierAndName() couldn't find Assets.car in bundle with identifier: '(null)'"?

您还可以尝试发布使用最新 Xcode 版本构建的应用程序的新版本，并希望相关客户更新应用程序并解决问题。
