iCloud访问所有类型的文件＃

Question

我想在我的iOS应用中选择任何类型的文件（.pdf，.docs，.xlsx，.jpeg，.txt，.rtf等）。点击上传按钮，我希望我的应用打开目录并选择文件（DocumentsPicker）

@IBAction pickDocument(sender: UIButton) {
    //Open Document Picker
}

在Swift中执行此操作的方法是什么？

Answer 1

根据您项目的功能，同时启用iCloud和Key-Sharing。

在您的类中导入MobileCoreServices，最后在UIViewController中扩展以下三个类：

UIDocumentMenuDelegate,UIDocumentPickerDelegate,UINavigationControllerDelegate

实施以下功能：

 public func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
              guard let myURL = urls.first else {
                   return
              }
              print("import result : \(myURL)")
    }


public func documentMenu(_ documentMenu:UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {
        documentPicker.delegate = self
        present(documentPicker, animated: true, completion: nil)
    }


func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
            print("view was cancelled")
            dismiss(animated: true, completion: nil)
    }

如何调用所有这些？将以下位代码添加到您的点击功能..

func clickFunction(){

let importMenu = UIDocumentMenuViewController(documentTypes: [String(kUTTypePDF)], in: .import)
            importMenu.delegate = self
            importMenu.modalPresentationStyle = .formSheet       
            self.present(importMenu, animated: true, completion: nil)
}

单击您的按钮。将弹出以下菜单..

在DropBox的情况下。点击任何项目。您将被重定向回您的应用程序，并且该URL将记录在您的终端中。

根据需要操作documentTypes。在我的应用程序中，用户只允许使用Pdf。所以，适合自己。

kUTTypePDF kUTTypePNG kUTTypeJPEG ...

此外，如果您想要自定义自己的菜单栏。添加以下代码并在处理程序

中自定义您自己的函数

        importMenu.addOption(withTitle: "Create New Document", image: nil, order: .first, handler: { print("New Doc Requested") })

享受它。

Answer 2

您可以使用UIDocumentPickerViewController从文件应用或iCloud Drive中获取文件。

从Key-value storage功能

iCloud Documents

iCloud

在要打开文档选择器的视图控制器上导入以下框架：
```
import MobileCoreServices
```

从UIDocumentPickerDelegate：

实施以下方法

func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
     // you get from the urls parameter the urls from the files selected
}

创建UIDocumentPickerViewController以显示文件选择器或iCloud Drive：

let types: [String] = [kUTTypePDF as String]
let documentPicker = UIDocumentPickerViewController(documentTypes: types, in: .import)
documentPicker.delegate = self
documentPicker.modalPresentationStyle = .formSheet
self.present(documentPicker, animated: true, completion: nil)

如果您希望用户可以向您的应用导入更多类型的文件，则必须向UTType types添加更多NSArray个。要查看所有可用类型，您可以查看UTType Docs

当在iOS 11上打开文档选择器并且您尝试在Google云端硬盘中选择一个文件时，由于错误导致文件被禁用：http://www.openradar.me/24187873

Answer 3

自iOS11起，UIDocumentMenuViewController已过时。从模态视图控制器显示时，我也发现它有问题。这是使用选择器的直接方法：

import MobileCoreServices

private func attachDocument() {
    let types = [kUTTypePDF, kUTTypeText, kUTTypeRTF, kUTTypeSpreadsheet]
    let importMenu = UIDocumentPickerViewController(documentTypes: types as [String], in: .import)

    if #available(iOS 11.0, *) {
        importMenu.allowsMultipleSelection = true
    }

    importMenu.delegate = self
    importMenu.modalPresentationStyle = .formSheet

    present(importMenu, animated: true)
}

extension AViewController: UIDocumentPickerDelegate, UINavigationControllerDelegate {
    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
        viewModel.attachDocuments(at: urls)
    }

     func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
}

像往常一样，别忘了添加iCloud支持：

Answer 4

UIDocumentPickerViewController(documentTypes: [String], in: UIDocumentPickerMode) 在 iOS 14.0 中被弃用

现在是 UIDocumentPickerViewController(forOpeningContentTypes: [UTType])

ContentTypes 是以下任何一种或组合：(UTType.image, UTType.text, UTType.plainText, UTType.utf8PlainText, UTType.utf16ExternalPlainText, UTType.utf16PlainText, UTType.delimitedText, UTType.commaSeparatedText, UTType.commaSeparatedText tabSeparatedText、UTType.utf8TabSeparatedText、UTType.rtf、UTType.pdf、UTType.webArchive、UTType.image、UTType.jpeg、UTType.tiff、UTType.gif、UTType.png、UTType.bmp、UTType.ico、UTType.rawImage、 UTType.svg、UTType.livePhoto、UTType.movie、UTType.video、UTType.audio、UTType.quickTimeMovie、UTType.mpeg、UTType.mpeg2Video、UTType.mpeg2TransportStream、UTType.mp3、UTType.mpeg4Movie、UTType.mpeg4Audio avi、UTType.aiff、UTType.wav、UTType.midi、UTType.archive、UTType.gzip、UTType.bz2、UTType.zip、UTType.appleArchive、UTType.spreadsheet、UTType.epub)

这对我来说是这样的：

let supportedTypes = [myArrayFromAnyOfTheAbove]

func openDocument() {
    let documentPicker = UIDocumentPickerViewController(forOpeningContentTypes: supportedTypes, asCopy: true)
    documentPicker.delegate = self
    documentPicker.allowsMultipleSelection = false
    documentPicker.shouldShowFileExtensions = true
    present(documentPicker, animated: true, completion: nil)
}

Answer 5

您可以使用NSURLSession实现您所描述的内容。

您必须将显示的目标目录限制在应用程序的文档目录中。应用没有对文件系统的完全访问权限。

Answer 6

这将有助于您实现下载/上传功能

UIDocumentMenuViewController *importMenu = [[UIDocumentMenuViewController alloc] initWithDocumentTypes:@[@"public.item"] inMode:UIDocumentPickerModeImport | UIDocumentPickerModeExportToService];

iCloud访问所有类型的文件＃

func openiCloudDocuments(){
    let importMenu = UIDocumentPickerViewController(documentTypes: [String("public.data")], in: .import)
    importMenu.delegate = self
    importMenu.modalPresentationStyle = .formSheet
    self.present(importMenu, animated: true, completion: nil)
}

Answer 8

我苦恼的是如何为PickerView指定一些特定格式，例如.pptx和.xlsx文件。这是一些代码，用于创建具有一些常用类型的PickerView ...

let types: [String] = [
    kUTTypeJPEG as String,
    kUTTypePNG as String,
    "com.microsoft.word.doc",
    "org.openxmlformats.wordprocessingml.document",
    kUTTypeRTF as String,
    "com.microsoft.powerpoint.ppt",
    "org.openxmlformats.presentationml.presentation",
    kUTTypePlainText as String,
    "com.microsoft.excel.xls",
    "org.openxmlformats.spreadsheetml.sheet",
    kUTTypePDF as String,
    kUTTypeMP3 as String
]
let documentPicker = UIDocumentPickerViewController(documentTypes: types, in: .import)
documentPicker.delegate = self
documentPicker.modalPresentationStyle = .formSheet
self.present(documentPicker, animated: true, completion: nil)

我发现有两个地方可以用来整理此列表：
