我是一个新程序员。尝试使用在我的搜索中返回的数据来填充UITableView
. 目前,我只需将地图放大到带注释的区域,但想呈现信息的表格视图。
import UIKit
import MapKit
class LocationSearch: UIViewController, UISearchBarDelegate {
var searchResults = [MKMapItem]()
@IBOutlet weak var myMapView: MKMapView!
@IBOutlet var tableView: UITableView!
@IBAction func searchButton(_ sender: Any)
{
let searchController = UISearchController(searchResultsController: nil)
searchController.searchBar.delegate = self
present(searchController, animated: true, completion: nil)
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar)
{
//Ignoring user
UIApplication.shared.beginIgnoringInteractionEvents()
//Activity Indicator
let activityIndicator = UIActivityIndicatorView()
activityIndicator.style = UIActivityIndicatorView.Style.gray
activityIndicator.center = self.view.center
activityIndicator.hidesWhenStopped = true
activityIndicator.startAnimating()
self.view.addSubview(activityIndicator)
//Hide search bar
searchBar.resignFirstResponder()
dismiss(animated: true, completion: nil)
//Create the search request
let searchRequest = MKLocalSearch.Request()
searchRequest.naturalLanguageQuery = searchBar.text
let activeSearch = MKLocalSearch(request: searchRequest)
activeSearch.start { (response, error) in
activityIndicator.stopAnimating()
UIApplication.shared.endIgnoringInteractionEvents()
if response == nil
{
print("ERROR")
}
else
{
//Remove annotations
let annotations = self.myMapView.annotations
self.myMapView.removeAnnotations(annotations)
//Getting data
let latitude = response?.boundingRegion.center.latitude
let longitude = response?.boundingRegion.center.longitude
//Create annotation
let annotation = MKPointAnnotation()
annotation.title = searchBar.text
annotation.coordinate = CLLocationCoordinate2DMake(latitude!, longitude!)
self.myMapView.addAnnotation(annotation)
//Zooming in on annotation
let coordinate:CLLocationCoordinate2D = CLLocationCoordinate2DMake(latitude!, longitude!)
let span = MKCoordinateSpan(latitudeDelta: 0.1, longitudeDelta: 0.1)
let region = MKCoordinateRegion(center: coordinate, span: span)
self.myMapView.setRegion(region, animated: true)
}
