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

Question

这就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

PS：

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

在呈现前确保浏览器布局UIDocumentPickerViewController按照设备的布局方向根据语言UIDocumentPickerViewController

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

Answer 2

一个简单的

documentPicker.view.semanticContentAttribute = .forceLeftToRight

解决了这个问题，但我仍然觉得它很奇怪。

documentPicker.allowsMultipleSelection = true
self.present(documentPicker, animated: true)
