如何在HERE MAP iOS上从经纬度获取完整地址

Question

I want to fetch full address by latitude and longitude in here map iOS premium sdk.In Android, I see there is the option to fetch address by latitude and longitude with ReverseGeocodeRequest but I did not find anything for iOS.

Currently, I am fetching the address from CLLocationCoordinate2D but I think it will be better if I will fetch it by HERE MAP sdk because I am using HERE MAP not Apple MAP. I have attached the android code below.

GeoCoordinate vancouver = new GeoCoordinate(latitude,longitude);

        new ReverseGeocodeRequest(vancouver).execute(new ResultListener<Location>() {

            @Override

            public void onCompleted(Location location, ErrorCode errorCode) {

                try {

                    assetData.address = location.getAddress().toString().replace("\n", "");



                } catch (NullPointerException e) {

                    e.printStackTrace();

                }



            }

        });

Answer 1

You have to make use of NMAAddress class in the HERE iOS SDK.

NMAAddress provides textual address information including house number, street name, city, country, district and more. It encompasses everything about an address or a point on the map. The NMAPlaceLocation class represents an area on the map where additional attributes can be retrieved. These additional attributes include NMAAddress, unique identifier, label, location, access locations, and NMAGeoBoundingBox for the location

Please check the document section Geocoding and Reverse Geocoding for more details including sample codes.

You need to use Google API to fetch address from Geo Coordinates, for that please use following code

func getAddressFromLatLong(latitude: Double, longitude : Double) {
    let url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=\(latitude),\(longitude)&key=YOUR_API_KEY_HERE"

    Alamofire.request(url).validate().responseJSON { response in
        switch response.result {
        case .success:

            let responseJson = response.result.value! as! NSDictionary

            if let results = responseJson.object(forKey: "results")! as? [NSDictionary] {
                if results.count > 0 {
                    if let addressComponents = results[0]["address_components"]! as? [NSDictionary] {
                        self.address = results[0]["formatted_address"] as? String
                        for component in addressComponents {
                            if let temp = component.object(forKey: "types") as? [String] {
                                if (temp[0] == "postal_code") {
                                    self.pincode = component["long_name"] as? String
                                }
                                if (temp[0] == "locality") {
                                    self.city = component["long_name"] as? String
                                }
                                if (temp[0] == "administrative_area_level_1") {
                                    self.state = component["long_name"] as? String
                                }
                                if (temp[0] == "country") {
                                    self.country = component["long_name"] as? String
                                }
                            }
                        }
                    }
                }
            }
        case .failure(let error):
            print(error)
        }
    }
}
