履行
首先,让你的类符合 UISearchResultsUpdating
协议。
class MyTableViewController: UITableViewController, UISearchResultsUpdating {}
添加搜索控制器属性:
class MyTableViewController: UTableViewController, UISearchResultsUpdating {
let searchController = UISearchController(searchResultsController: nil)
}
添加搜索栏:
override func viewDidLoad() {
super.viewDidLoad()
searchController.searchResultsUpdater = self
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
searchController.searchBar.sizeToFit()
self.tableView.tableHeaderView = searchController.searchBar
}
最后,实现来自 UISearchResultsUpdating
协议的 updateSearchResultsForSearchController
方法:
func updateSearchResultsForSearchController(searchController: UISearchController) {
}
