Swift-如何摆脱UISearchController中的深色背景？

Question

我有这个黑暗的背景：

image of the problem

这是我的代码：

class SearchController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate {

    let searchController = UISearchController(searchResultsController: nil)

    override func viewDidLoad() {

        searchController.searchBar.delegate = self

        searchController.searchResultsUpdater = self as? UISearchResultsUpdating
        self.definesPresentationContext = true

        self.navigationItem.titleView = searchController.searchBar

        searchController.hidesNavigationBarDuringPresentation = false

        self.definesPresentationContext = true

    }

}

我该怎么办？ 谢谢！
