ios中的缩略图关联?

以前是否有人遇到过无法关联缩略图错误?有没有简单的解决办法?以下是它中断的代码:
extension TestPdfEpubViewController: UIDocumentPickerDelegate {
func documentPicker(_ controller: UIDocumentPickerViewController, didPickDocumentsAt urls: [URL]) {
guard let selectedFileURL = urls.first else { return }
//create pdf first
let documentFileURL = Bundle.main.url(forResource: selectedFileURL.absoluteString, withExtension: "pdf")!
let document = PDFDocument(url: documentFileURL)!
//then display the pdf
let readerController = PDFViewController.createNew(with: document)
navigationController?.pushViewController(readerController, animated: true)
}
}
你跟这个表演的人打交道运气好吗?
