履行
首先,讓你的類符合 UISearchResultsUpdating
協議。
class MyTableViewController: UITableViewController, UISearchResultsUpdating {}
新增搜尋控制器屬性:
class MyTableViewController: UTableViewController, UISearchResultsUpdating {
let searchController = UISearchController(searchResultsController: nil)
}
新增搜尋欄:
override func viewDidLoad() {
super.viewDidLoad()
searchController.searchResultsUpdater = self
searchController.hidesNavigationBarDuringPresentation = false
searchController.dimsBackgroundDuringPresentation = false
searchController.searchBar.sizeToFit()
self.tableView.tableHeaderView = searchController.searchBar
}
最後,實現來自 UISearchResultsUpdating
協議的 updateSearchResultsForSearchController
方法:
func updateSearchResultsForSearchController(searchController: UISearchController) {
}
