有没有办法获取原始文件未下载的filSize属性？我得到了fileURL和UIDocumentPickerViewController，然后我试图检查fileSize，但似乎它只是尚未下载的原始文件的别名。尺寸也不对。

debugPrint("size: ", try? fileURL.resourceValues(forKeys: [.fileSizeKey, .ubiquitousItemDownloadingStatusKey]))

"fileURL: " file:///private/var/mobile/Library/Mobile%20Documents/com~apple~CloudDocs/Downloads/.vvvvv.mp4.icloud
"size: " Optional(Foundation.URLResourceValues(_values: [__C.NSURLResourceKey(_rawValue: NSURLUbiquitousItemDownloadingStatusKey): NSURLUbiquitousItemDownloadingStatusNotDownloaded, __C.NSURLResourceKey(_rawValue: NSURLFileSizeKey): 340], _keys: Set([__C.NSURLResourceKey(_rawValue: NSURLUbiquitousItemDownloadingStatusKey), __C.NSURLResourceKey(_rawValue: NSURLFileSizeKey)])))

试试这个：

func getFileSize(fileURL: URL?) -> Int64? {
    guard let fileURL,
          fileURL.startAccessingSecurityScopedResource(),
          let fileAttributes = try? FileManager.default.attributesOfItem(atPath: fileURL.path),
          let fileSizeInBytes = fileAttributes[.size] as? Int64 else {
        return nil
    }

    fileURL.stopAccessingSecurityScopedResource()

    return fileSizeInBytes
}
