在“我的iPhone"文件夹中，如何为我的应用程序创建文件夹?[iOS 13] [英] On My iPhone folders, how to create a folder for my app? [iOS 13]

问题描述

我想在文件"应用中为我的应用创建一个文件夹，以便在我要从应用中保存文件时进行访问

I am trying to create a folder for my app in the Files app for access when i want to save a file from my app

在iOS 12及更低版本中，我可以通过启用

In iOS 12 and earlier i could achieve this by enabling

应用程序支持iTunes文件共享，并且支持就地打开文档，如下所示

自从更新到iOS 13之后，不再显示与iOS 12中不再显示的文件夹相同的文件夹.

Since updating to iOS 13, the same folder that used to show up in iOS 12 no-longer shows.

发生了什么变化，如何在iOS 13中解决此问题?

What has changed and how can i get this resolved in iOS 13?

我使用以下扩展名保存文件:

I use the extension below to save files:

extension WebViewController:  URLSessionDownloadDelegate {
    func urlSession(_ session: URLSession, downloadTask: URLSessionDownloadTask, didFinishDownloadingTo location: URL) {

        // create destination URL with the original pdf name
        guard let url = downloadTask.originalRequest?.url else { return }
        let documentsPath = FileManager.default.urls(for: .cachesDirectory, in: .userDomainMask)[0]
        let destinationURL = documentsPath.appendingPathComponent(url.lastPathComponent)
        // delete original copy
        try? FileManager.default.removeItem(at: destinationURL)
        // copy from temp to Document
        do {
            try FileManager.default.copyItem(at: location, to: destinationURL)
             DispatchQueue.main.asyncAfter(deadline: .now() + 0.2){
            let activityViewController = UIActivityViewController(activityItems: [self.fileName, destinationURL], applicationActivities: nil)
                if(UIDevice.current.userInterfaceIdiom == .pad){
                    if let popOver = activityViewController.popoverPresentationController {
                        popOver.sourceView = self.view
                        popOver.sourceRect = self.view.bounds
                        popOver.barButtonItem = self.navigationItem.rightBarButtonItem
                        self.present(activityViewController, animated: true, completion: nil)
                    }
                }
                else{
                    self.present(activityViewController, animated: true, completion: nil)
                }
            }
        } catch let error {
            print("Copy Error: \(error.localizedDescription)")
        }
    }
}
