我启用了文档类型,可以将文件从其他应用程序导入或复制到我的应用程序。我有一些问题:

1 - 应该在哪里创建从Inbox到Document目录移动文件的方法?这是对的地方吗? func applicationWillEnterForeground(_ application: UIApplication)

2 - 在第一个视图控制器上,我从文档目录中获取文件:

  func getFileListByDate() -> [String]? {

        let directory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
        if let urlArray = try? FileManager.default.contentsOfDirectory(at: directory,
                                                                       includingPropertiesForKeys: [.contentModificationDateKey],
                                                                       options:.skipsHiddenFiles) {

            return urlArray.map { url in
                (url.lastPathComponent, (try? url.resourceValues(forKeys: [.contentModificationDateKey]))?.contentModificationDate ?? Date.distantPast)
                }
                .sorted(by: { $0.1 > $1.1 }) // sort descending modification dates
                .map { $0.0 } // extract file names

        } else {
            return nil
        }

    }

但是当文件导入我的应用程序时,我的表视图中有Inbox文件夹(项目),如何自动将文件从Inbox移动到Document目录并删除收件箱文件夹?

如果您的应用需要打开来自其他应用的文件,则需要实现委托方法

for i in range ( 1, 31 ): 
    upso_list = sel.xpath ( '//*[@id="List_' + str(i) + '"]/div[4]/span/a/text()').extract()

并将网址移至您应用内所选的文件夹中。

func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {

将文件从收件箱移出到您的目标网址,例如附加url.lastPathComponent的文档目录:

let url = url.standardizedFileURL  // this will strip out the private from your url
// if you need to know which app is sending the file or decide if you will open in place or not you need to check the options  
let openInPlace = options[.openInPlace] as? Bool == true
let sourceApplication = options[.sourceApplication] as? String
let annotation = options[.annotation] as? [String: Any]
// checking the options info
print("openInPlace:", openInPlace)
print("sourceApplication:", sourceApplication ?? "")
print("annotation:", annotation ?? "")
