Question

我正在创建一个已经拥有基于ios mapkit的登记功能的应用程序。目前它只显示城市和国家，但我的客户想要更多。 Het希望能够在像Instagram这样的地方办理登机手续..（以地点名称为例，Restoname ..）

我想知道这是否可以使用mapkit库？如果是这样的话，任何人都有代码例子。 ??

听起来你想要使用地方标记和注释。创建MapView时，请确保其符合MKMapViewDelegate：

extension ViewController: MKMapViewDelegate {
    func mapView(_ mapView: MKMapView, didAdd views: [MKAnnotationView]) {
        // once annotationView is added to the map, get the last one added unless it is the user's location:
        if let annotationView = views.last {
            // show callout programmatically:
            mapView.selectAnnotation(annotationView.annotation!, animated: false)
            // zoom to all annotations on the map:
            mapView.showAnnotations(mapView.annotations, animated: true)
        }
    }
}

然后你可以从一个字符串中对一个地址进行地理定位（这就是写出来的地址：123 Fake St.，New York，NY ....

func createGeoLocationFromAddress(_ address: String, mapView: MKMapView) {


    let completion:CLGeocodeCompletionHandler = {(placemarks: [CLPlacemark]?, error: Error?) in

        if let placemarks = placemarks {
            for placemark in placemarks {

                mapView.removeAnnotations(mapView.annotations)
                // Instantiate annotation
                let annotation = MKPointAnnotation()
                // Annotation coordinate
                annotation.coordinate = (placemark.location?.coordinate)!
                annotation.title = placemark.thoroughfare! + ", " + placemark.subThoroughfare!
                annotation.subtitle = placemark.subLocality
                mapView.addAnnotation(annotation)
                mapView.showsPointsOfInterest = true
                self.centerMapOnLocation(placemark.location!, mapView: mapView)

            }

        } else {

        }

    }

    CLGeocoder().geocodeAddressString(address, completionHandler: completion)

}

func centerMapOnLocation(_ location: CLLocation, mapView: MKMapView) {
    let regionRadius: CLLocationDistance = 1000
    let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate, regionRadius * 2.0, regionRadius * 2.0)
    mapView.setRegion(coordinateRegion, animated: true)
}

然后您只需调用

即可将注释放在地图上

createGeoLocationFromAddress(addressString, mapView: mapKit)

这应该有效。希望它有所帮助
