ios - PHAssetResourceManager writeData 返回错误 1

Question

我正在尝试分享 PHAssetResource与原始文件名。此方法将 Assets 资源保存到临时目录并从那里共享。自 iOS 13 以来，这一直出现错误:

let tempDirectory = NSTemporaryDirectory() as NSString
let partialPath = tempDirectory.appendingPathComponent(sentAssetResource.originalFilename)
let fileURL = URL(fileURLWithPath: partialPath)

let options = PHAssetResourceRequestOptions()
options.isNetworkAccessAllowed = true


PHAssetResourceManager.default().writeData(for: sentAssetResource, toFile: fileURL, options: options, completionHandler: { (error) in

    if (error != nil) {

        print (error?.localizedDescription)
        return
    }

    DispatchQueue.main.async {
        let activityViewController = UIActivityViewController(activityItems: [fileURL],  applicationActivities: nil)

        activityViewController.completionWithItemsHandler = {
            (activity, success, items, error) in

            if FileManager.default.fileExists(atPath: fileURL.path) {
                try? FileManager.default.removeItem(atPath: fileURL.path)
            }
        }

        self.present(activityViewController, animated: true, completion: {


        })
    }
})

收到的错误是:

The operation couldn't be completed.
(PHPhotosErrorDomain error -1.)

这里有什么问题？

我不得不切换到 PHAssetResourceManager.default().requestData ，但是这个共享没有正确的文件名。

在我的测试中，该方法在 iOS 13.2 上运行良好。该方法可能会因数据库错误而失败(iOS 照片库是 CoreData 数据库，AssetResources 是单独的表)。您能否在模拟器以及所有测试设备上重现该问题？
