我需要打开UIDocumentPickerViewController，它应该允许用户选择所有类型的文件。即.（.pdf，.doc）文件我用的是UIDocumentPickerViewController方法。验证码：
我的类声明中的UIDocumentPickerDelegate, UIDocumentMenuDelegate
//上传文件

func OpenFile(){

    let importMenu = UIDocumentMenuViewController(documentTypes: [String(kUTTypePNG),String(kUTTypeImage)], in: .import)
    importMenu.delegate = self
    importMenu.modalPresentationStyle = .fullScreen
    self.present(importMenu, animated: true, completion: nil)

}
@available(iOS 8.0, *)
public func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {        
    let cico = url as URL
    print("The Url is : \(cico)")

    do {
        let weatherData = try NSData(contentsOf: cico, options: NSData.ReadingOptions())
        print(weatherData)
        let activityItems = [weatherData]
        let activityController = UIActivityViewController(activityItems: activityItems, applicationActivities: nil)
        if UI_USER_INTERFACE_IDIOM() == .phone {
            self.present(activityController, animated: true, completion: { _ in })
        }
        else {
            let popup = UIPopoverController(contentViewController: activityController)
            popup.present(from: CGRect(x: CGFloat(self.view.frame.size.width / 2), y: CGFloat(self.view.frame.size.height / 4), width: CGFloat(0), height: CGFloat(0)), in: self.view, permittedArrowDirections: .any, animated: true)
        }

    } catch {
        print(error)
    }

    //optional, case PDF -> render
    //displayPDFweb.loadRequest(NSURLRequest(url: cico) as URLRequest)      

}

@available(iOS 8.0, *)
public func documentMenu(_ documentMenu:     UIDocumentMenuViewController, didPickDocumentPicker documentPicker: UIDocumentPickerViewController) {

    documentPicker.delegate = self
    present(documentPicker, animated: true, completion: nil)        
} 

func documentPickerWasCancelled(_ controller: UIDocumentPickerViewController) {

    print(" cancelled by user")

    dismiss(animated: true, completion: nil)        

}

在此代码中，应用程序将崩溃。原因是Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'You cannot initialize a UIDocumentPickerViewController except by the initWithDocumentTypes:inMode: and initWithURL:inMode: initializers.
我不知道如何初始化initWithDocumentTypes:inMode.我是新的iOS任何一个帮助我？你能不能帮帮我。

Swift 3*，4*，
要打开文档并选择任何文档，您使用的是UIDocumentPickerViewController，如果用户设备中连接了Google Drive，则会显示iCloud、文件和Google Drive中的所有文档。然后选择的文档需要下载到您的应用程序中，从那里您可以在WKWebView中显示它，

@IBAction func uploadNewResumeAction(_ sender: Any) {

  /*  let documentPicker = UIDocumentPickerViewController(documentTypes: ["com.apple.iwork.pages.pages", "com.apple.iwork.numbers.numbers", "com.apple.iwork.keynote.key","public.image", "com.apple.application", "public.item","public.data", "public.content", "public.audiovisual-content", "public.movie", "public.audiovisual-content", "public.video", "public.audio", "public.text", "public.data", "public.zip-archive", "com.pkware.zip-archive", "public.composite-content", "public.text"], in: .import) */

    let documentPicker = UIDocumentPickerViewController(documentTypes: ["public.text", "com.apple.iwork.pages.pages", "public.data"], in: .import)

    documentPicker.delegate = self
    present(documentPicker, animated: true, completion: nil)
}

   extension YourViewController: UIDocumentPickerDelegate{

      func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {

                let cico = url as URL
                print(cico)
                print(url)

                print(url.lastPathComponent)

                print(url.pathExtension)

               }
   }

注意：如果你想选择所有的文件，你必须使用以下代码：

let documentPicker = UIDocumentPickerViewController(documentTypes: ["com.apple.iwork.pages.pages", "com.apple.iwork.numbers.numbers", "com.apple.iwork.keynote.key","public.image", "com.apple.application", "public.item","public.data", "public.content", "public.audiovisual-content", "public.movie", "public.audiovisual-content", "public.video", "public.audio", "public.text", "public.data", "public.zip-archive", "com.pkware.zip-archive", "public.composite-content", "public.text"], in: .import)

在你的行动方法中。

在Swift中使用UIDocumentPickerViewController打开**（.pdf，.doc，.docx）**的具体文档文件：documentTypes应该是
导入import MobileCoreServices

["com.microsoft.word.doc","org.openxmlformats.wordprocessingml.document", kUTTypePDF as String]

示例：

let importMenu = UIDocumentPickerViewController(documentTypes: ["com.microsoft.word.doc","org.openxmlformats.wordprocessingml.document", kUTTypePDF as String], in: UIDocumentPickerMode.import) 
importMenu.delegate = self 
self.present(importMenu, animated: true, completion: nil)

实际上，除了使用WebView，您还可以使用QuickLook*Framework**，该框架就是为此特定目的而设计的。您只需传递文件的位置并遵守协议。它将显示一个视图控制器，其中包含文档。

支持以下文件：*
- iWork文档（页面、数字和主题演讲）
- Microsoft Office文档（只要它们是使用Office 97或任何其他更新版本创建的）
- PDF文件
-图片
-文本文件
-富文本格式文档
-逗号分隔值文件（csv）

Here是APPCODA的教程，描述了相同的内容。
和
Here是苹果OBJ-C版本提供的教程。

UIDocumentPickerViewController.init(documentTypes:in:)和kUTType___分别在iOS 14和15中弃用。以下是如何在较新版本的iOS上实现相同的功能：

let contentTypes: [UTType] = [
    .init(filenameExtension: "doc")!,
    .init(filenameExtension: "docx")!,
    .pdf
]

let documentPicker = UIDocumentPickerViewController.init(forOpeningContentTypes: contentTypes)
documentPicker.delegate = self
present(documentPicker, animated: true)
