Additional data
Allow your users to request for a set of extra entities, like city or country outline, previously retrieved from the Online Search service. For more information, refer to the Additional Data service documentation.
Sample use case: You want to apply colors to geographic-boundary areas such as countries, cities or districts.
Use the code below to try this in your app:
TTAdditionalDataSources *ads = [[searchResult firstObject] additionalDataSources];
TTGeometryDataSource *gds = [ads geometryDataSource];
TTAdditionalDataSearchQuery *query = [[TTAdditionalDataSearchQueryBuilder createWithDataSource:gds] build];
[[TTAdditionalDataSearch new] additionalDataSearchWithQuery:query completionHandler:^(TTAdditionalDataSearchResponse * _Nullable result, TTResponseError * _Nullable error) {
PolygonAdditionalDataVisitior *visitior = [PolygonAdditionalDataVisitior new];
[[[result results] firstObject] visitResult:visitior];
[self drawingPolygonAdditionalDataVisitior:visitior];
}];
Sample views utilizing entities retrieved from the Additional Data service:
 Boundaries for Amsterdam |
 Boundaries for Poland |
