推荐答案

我在下面提到的代码中添加了几种类型，请检查它是否可以解决您的问题:

I have added couple of types in the below mentioned code, please check if it solves your issue:

let types: [String] = [kUTTypePDF as String,kUTTypeSpreadsheet as String, kUTTypePresentation as String, "com.apple.iwork.pages.pages", "public.text"]
let documentPicker = UIDocumentPickerViewController(documentTypes: types, in: .import)
documentPicker.delegate = self
documentPicker.modalPresentationStyle = .formSheet
self.present(documentPicker, animated: true, completion: nil)

.

您可以尝试的其他可用类型:

"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.movi​​e"， "public.audiovisual-content"，"public.video"，"public.audio"， "public.text"，"public.data"，"public.zip-archive"， "com.pkware.zip-archive"，"public.composite-content"，"public.text"，"com.microsoft.word.doc"
