如何显示来自iclouds的特定文件格式源自iOS Swift [英] How to show particular file format from iclouds derive in ios swift

问题描述

在我的应用程序中，从iclouds导出文件。想要上传xlsx，docx，txt。

In my application upload the file from iclouds derive. want to upload xlsx, docx, txt.

想要上传xlsx文件，意味着从iclouds导出只希望显示xlsx而不显示其他文件。[docx，txt]

want to upload the xlsx file means from iclouds derive want to display only xlsx another files should not display.[docx,txt]

相同，如果用户要显示docx文件意味着不应显示xlsx和txt，则xlsx文件不应显示。

same if the user want to display docx file means xlsx and txt ,xlsx file should not be display.

此处是我的代码

 @IBAction func moveiclouds_BtnClick(_ sender: Any) {
        let documentPicker = UIDocumentPickerViewController(documentTypes: [kUTTypePDF as String, "com.microsoft.word.doc", "com.microsoft.excel.xls", kUTTypeCompositeContent as String, kUTTypeJPEG as String], in: .import)
        documentPicker.delegate = self
        self.present(documentPicker, animated: true, completion: nil)
    }


extension CreateFeesView: UIDocumentPickerDelegate{
    func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentAt url: URL) {
        let cico = url as URL
        cico_files = cico
        filepath_fees = url.pathExtension
    }
}

派生出所有文件都在最近添加的列表中显示。希望仅在列表中显示特定文件。如何达到帮助我。感谢Advance

推荐答案

在创建文档时只需调整 documentTypes：参数选择器。

Just adjust the documentTypes: argument when creating your document picker.

documentTypes：[ org.openxmlformats.wordprocessingml.document]

将只允许用户选择docx文件。

will let the user only select docx files.

documentTypes：[ org.openxmlformats.spreadsheetml.sheet ]

仅允许用户选择xlsx文件。

will let the user only select xlsx files.
