使用 SearchController 推送 ViewController,在搜索栏下方显示黑色矩形

Pushing ViewController with SearchController showing black rectangle under Search Bar

当我将另一个控制器推入堆栈时(当有一个搜索控制器时)我在搜索栏下方看到一个黑色方块。我已将以下所有内容的背景颜色设置为白色;

返回堆栈时也会出现。

搜索控制器

func setUpSearchController() {
        searchController.delegate = self
        searchController.view.backgroundColor = .white
        searchController.searchBar.backgroundColor = .white
        searchController = UISearchController(searchResultsController: nil)
        searchController.hidesNavigationBarDuringPresentation = true
        searchController.dimsBackgroundDuringPresentation = true
        searchController.searchBar.sizeToFit()
        searchController.searchBar.backgroundColor = .white
        searchController.searchBar.barTintColor = .white
        searchController.searchBar.placeholder = "Search"
        searchController.searchBar.searchBarStyle = .minimal
        searchController.searchBar.tintColor = Colours.brandGreen
        definesPresentationContext = true
        if #available(iOS 11.0, *) {
            navigationItem.searchController = searchController
            navigationItem.hidesSearchBarWhenScrolling = true
        } else {
            messagesTableView.tableHeaderView = searchController.searchBar
        }
    }

有没有 Select 小区

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        let chatController = ChatController()
        let message = messages[indexPath.row]
        chatController.title = message
        self.navigationController?.pushViewController(chatController, animated: true)
    }

一如既往,非常感谢任何帮助。

代码

guard let navigationController = navigationController else { return }
navigationController.view.backgroundColor = .white

正如上面 link 解释的那样,这不能全局设置,因此,需要在我将使用的每个 NC 上设置。
