我的目标是阻止取消按钮出现在UISearchController的搜索栏中.我从Apple的Table Search开始,使用UISearchController示例代码并隐藏了取消按钮,如下面的代码片段所示.但是,当用户点击文本字段时,仍会显示取消按钮.有帮助吗？

override func viewDidLoad() {
    super.viewDidLoad()

    resultsTableController = ResultsTableController()

    searchController = UISearchController(searchResultsController: resultsTableController)
    searchController.searchResultsUpdater = self
    searchController.searchBar.sizeToFit()
    tableView.tableHeaderView = searchController.searchBar

    searchController.searchBar.delegate = self

    //Hide cancel button - added by me
    searchController.searchBar.showsCancelButton = false

    ...
