UIDocumentPickerViewController 部分机型文件选择器的滚动视图与顶部导航栏重叠

iOS 18 未发现问题 主要发现问题系统iOS16、iOS17

UIDocumentPickerViewController *documentPicker = [[UIDocumentPickerViewController alloc] initWithDocumentTypes:types inMode:UIDocumentPickerModeImport];
    documentPicker.delegate = self;
    documentPicker.modalPresentationStyle = UIModalPresentationFullScreen;
    // 修复部分机型界面重叠问题：文件选择器的滚动视图与顶部导航栏重叠，导致部分内容被遮盖。
    BOOL originIsTranslucent = UINavigationBar.appearance.isTranslucent;
    UINavigationBar.appearance.translucent = NO;
    [self presentViewController:_documentPicker animated:YES completion:^{
        // 恢复原始设置
        UINavigationBar.appearance.translucent = originIsTranslucent;
    }];
