【问题描述】:
我正在尝试在 Google 地图上实现自动完成搜索,该搜索将使用标记显示用户在地图上选择的位置。
搜索工作正常。问题如下。当我从搜索结果中选择一个位置时,我得到一个 GMSPlace 对象,该对象具有正确的名称作为所选值、正确的地点 ID(使用此 link 确认),但坐标不正确(-180.0,-180.0 或 kCLLocationCoordinate2DInvalid持续的)。我在多个地点进行了测试。
大部分代码是从 documentation 借用的 Places API。
import UIKit
import GoogleMaps
import GooglePlaces
class ViewController: UIViewController, UISearchBarDelegate {
@IBOutlet weak var mapContainer: UIView!
var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
self.mapView = GMSMapView(frame: self.mapContainer.frame)
self.view.addSubview(self.mapView)
}
// Code from https://developers.google.com/places/ios-sdk/autocomplete#add_an_autocomplete_ui_control
@IBAction func searchByAddress(_ sender: Any) {
// Present the Autocomplete view controller when the button is pressed.
let autocompleteController = GMSAutocompleteViewController()
autocompleteController.delegate = self
// Specify the place data types to return.
let fields: GMSPlaceField = GMSPlaceField(rawValue: UInt(GMSPlaceField.name.rawValue) |
UInt(GMSPlaceField.placeID.rawValue))!
autocompleteController.placeFields = fields
// Display the autocomplete view controller.
present(autocompleteController, animated: true, completion: nil)
}
}
extension ViewController: GMSAutocompleteViewControllerDelegate {
// Handle the user's selection.
func viewController(_ viewController: GMSAutocompleteViewController, didAutocompleteWith place: GMSPlace) {
let position: CLLocationCoordinate2D = place.coordinate
let camera = GMSCameraPosition.camera(withLatitude: position.latitude, longitude: position.longitude, zoom: 10)
let newMapView = GMSMapView.map(withFrame: self.mapContainer.frame, camera: camera)
self.mapView = newMapView
self.view.addSubview(newMapView)
let marker = GMSMarker()
marker.position = position
marker.title = place.name
marker.map = self.mapView
viewController.dismiss(animated: true, completion: nil)
}
func viewController(_ viewController: GMSAutocompleteViewController, didFailAutocompleteWithError error: Error) {
// TODO: handle the error.
print("Error: ", error.localizedDescription)
}
// User canceled the operation.
func wasCancelled(_ viewController: GMSAutocompleteViewController) {
viewController.dismiss(animated: true, completion: nil)
}
// Turn the network activity indicator on and off again.
func didRequestAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func didUpdateAutocompletePredictions(_ viewController: GMSAutocompleteViewController) {
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
}
任何帮助将不胜感激!
