我正在使用以下代码:
class SearchViewController: UIViewController {
var searchCompleter = MKLocalSearchCompleter()
var searchResults = [MKLocalSearchCompletion]()
@IBOutlet weak var searchResultsTableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
searchCompleter.delegate = self
}
}
extension SearchViewController: UISearchBarDelegate {
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
searchCompleter.queryFragment = searchText
}
}
extension SearchViewController: MKLocalSearchCompleterDelegate {
func completerDidUpdateResults(_ completer: MKLocalSearchCompleter) {
searchResults = completer.results
searchResultsTableView.reloadData()
}
func completer(_ completer: MKLocalSearchCompleter, didFailWithError error: Error) {
// handle error
}
}
extension SearchViewController: UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return searchResults.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let searchResult = searchResults[indexPath.row]
let cell = UITableViewCell(style: .subtitle, reuseIdentifier: nil)
cell.textLabel?.text = searchResult.title
cell.detailTextLabel?.text = searchResult.subtitle
return cell
}
}
extension SearchViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
let completion = searchResults[indexPath.row]
let searchRequest = MKLocalSearchRequest(completion: completion)
let search = MKLocalSearch(request: searchRequest)
search.start { (response, error) in
let coordinate = response?.mapItems[0].placemark.coordinate
print(String(describing: coordinate))
}
}
}
但是,这只搜索本地而不是全局。如何对全局数据进行自动完成搜索?我无法获得是否有适用于 iOS 的 api 以及如何实现它。非常感谢您的帮助。
