如何隐藏弹出的UISearchController

let searchController = UISearchController(searchResultsController: nil)

searchController.hidesNavigationBarDuringPresentation = false

definesPresentationContext = true

extension YourViewController: UISearchResultsUpdating {
    func updateSearchResults(for searchController: UISearchController) {
        if searchController.isActive {
            // 隐藏搜索栏的逻辑
            searchController.searchBar.isHidden = true
        } else {
            // 显示搜索栏的逻辑
            searchController.searchBar.isHidden = false
        }
    }
}

searchController.searchResultsUpdater = self

navigationItem.searchController = searchController
