Polygons for reverse geocoding

Combine Additional Data Provider queries with Reverse Geocoding queries to obtain extra data about a specific entity Type like:

Country
CountrySubdivision
CountrySecondarySubdivision
CountryTertiarySubdivision
Municipality
MunicipalitySubdivision
Neighbourhood
PostalCodeArea

Sample use case: You want to display Country or Municipality boundaries.

Use the following code to try this in your app:

Create TTReverseGeocoderQuery with the entityType parameter and use Reverse Geocode search.

_

let query = TTReverseGeocoderQueryBuilder.create(with: coordinate).withEntityType(entityType)
    .build()
reverseGeocoder.reverseGeocoder(with: query)

TTReverseGeocoderQuery *query = [[[TTReverseGeocoderQueryBuilder createWithCLLocationCoordinate2D:coordinate] withEntityType:self.entityType] build];
[self.reverseGeocoder reverseGeocoderWithQuery:query];

Get the TTGeometryDataSource object from the Response.

_

guard let address = response.result.addresses.first else { return }
guard let additionalDataSources = address.additionalDataSources else { return }
guard let geometryDataSource = additionalDataSources.geometryDataSource else { return }

- (TTGeometryDataSource *_Nullable)geometryDataSourceFromResponse:(TTReverseGeocoderResponse *)response {
    if (response.result.addresses.firstObject != nil) {
        TTReverseGeocoderFullAddress *addressValue = [TTReverseGeocoderFullAddress alloc];
        addressValue = response.result.addresses.firstObject;
        if (addressValue.additionalDataSources) {
            TTAdditionalDataSources *additionalDataSources = [TTAdditionalDataSources alloc];
            additionalDataSources = addressValue.additionalDataSources;
            if (additionalDataSources.geometryDataSource) {
                return additionalDataSources.geometryDataSource;
            }
        }
    }
    return nil;
}

Use the TTAdditionalDataSearchQuery object for sending Requests with the TTGeometryDataSource object supported by the Additional Data API.

_

let query = TTAdditionalDataSearchQueryBuilder.create(with: geometryDataSource)
    .withGeometriesZoom(geometriesZoom)
    .build()

searchAdditionalData.additionalDataSearch(with: query)

if ([self geometryDataSourceFromResponse:response] != nil) {
    TTAdditionalDataSearchQuery *query = [[[TTAdditionalDataSearchQueryBuilder createWithDataSource:[self geometryDataSourceFromResponse:response]] withGeometriesZoom:geometriesZoom] build];
    [_searchAdditionalData additionalDataSearchWithQuery:query];
}
