ios - UIDocumentPickerViewController 以阿拉伯语显示翻转的内容

Question

这是我打开文档选择器的方式

func openDocuments(){
        let documentPicker = UIDocumentPickerViewController(documentTypes: ["public.data"],in: .import)
        documentPicker.delegate = self
        documentPicker.modalPresentationStyle = .fullScreen

        self.present(documentPicker, animated: true) {
        }

    }

注意单元格如何翻转标签

附言:

我有

UIView.appearance().semanticContentAttribute = .forceRightToLeft

因为我正在开发的应用程序只有阿拉伯语

Answer 1

在呈现 UIDocumentPickerViewController 之前，请确保 UIDocumentPickerViewController 中的浏览器布局按照设备的布局方向根据语言呈现 UIDocumentPickerViewController

    if Locale.current.languageCode == "ar" {
        UIView.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).semanticContentAttribute = .forceRightToLeft
    } else {
        UIView.appearance(whenContainedInInstancesOf: [UIDocumentBrowserViewController.self]).semanticContentAttribute = .forceLeftToRight
    }
