Question

我正在使用swift创建地图。如何找到保存在Apple地图上的当前位置的名称，比如说我在沃尔玛，如何打印出该位置的名称，以及它是否只打印出一个地址。

我目前的代码是

class MapVC: UIViewController, CLLocationManagerDelegate {

@IBOutlet weak var map: MKMapView!

let manager = CLLocationManager()


func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    let location = locations[0]
    let span:MKCoordinateSpan = MKCoordinateSpanMake(0.01, 0.01)

    let mylocation:CLLocationCoordinate2D = CLLocationCoordinate2DMake(location.coordinate.latitude, location.coordinate.longitude)
    let region:MKCoordinateRegion = MKCoordinateRegionMake(mylocation, span)
    map.setRegion(region, animated: true)

    print(location.coordinate)
    print(location.coordinate.latitude)
    print(location.speed)

    self.map.showsUserLocation = true
    self.map.showsPointsOfInterest = true


}

override func viewDidLoad() {
    super.viewDidLoad()

    manager.delegate = self
    manager.desiredAccuracy = kCLLocationAccuracyBest
    manager.requestAlwaysAuthorization()
    manager.startUpdatingLocation()

}

您可以使用iOS原生API将经度和纬度转换为地名：

func reverseGeocodeLocation(_ location: CLLocation, 
          completionHandler: @escaping CLGeocodeCompletionHandler)

例如：

var geocoder = CLGeocoder()
geocoder.reverseGeocodeLocation(location, completionHandler: {(placemarks, error)->Void in

})

通过获取CLPlacemark类型的地标的第一个对象来获取地名。然后CLPlacemark的name属性就是你所追求的。
