Functionality varies by region. [Learn more](/maps/comms/eea/faq).\n\nYou can use the Places SDK for iOS and the\nGeocoding API with the Maps SDK for iOS to\nsearch for regions, and get more information about places. The\nPlaces SDK for iOS and Geocoding API\nare powerful and stable alternatives for obtaining [place\nIDs](/maps/documentation/places/ios-sdk/place-id). If you're already using place\nIDs, you can reuse those IDs with data-driven styling for boundaries.\n\nAdd Places and Geocoding to your Maps SDK for iOS apps in the following ways:\n\n- [Places SDK for iOS](/maps/documentation/places/ios-sdk) returns information about places using HTTP requests.\n- [CLGeocoder](https://developer.apple.com/documentation/corelocation/clgeocoder) class can geocode and reverse geocode dynamically from user input.\n- [Geocoding API](/maps/documentation/geocoding) lets you geocode static, known addresses.\n\n| **Note:** The [Places SDK for iOS](/maps/documentation/places/ios-sdk) and Geocoding API must be enabled, and are billed separately from the Maps SDK for iOS.\n\nUse the Places API\n\n- The [Places API Text\n Search](/maps/documentation/places/web-service/text-search) returns\n information about a set of places based on a string --- for example \"pizza in\n New York\" or \"shoe stores near Ottawa\" or \"123 Main Street\". The service\n responds with a list of places matching the text string and any location\n bias that has been set.\n\n- The [Places Autocomplete](/maps/documentation/places/ios-sdk/autocomplete#restrict_results_to_a_specific_region) service provides a convenient\n way to let your users search for regions. To display results within the\n defined region, set `locationRestriction` on\n [`GMSAutocompleteFilter`](/maps/documentation/places/ios-sdk/reference/objc/Classes/GMSAutocompleteFilter).\n\nGet place details for a region\n\n- The [Place Details](/maps/documentation/places/ios-sdk/place-details) data\n for a region is also effective. For example, you can:\n\n - Search for boundary place IDs based on place names.\n - Get the viewport for zooming to a boundary.\n - Get the feature type for the boundary (for example locality).\n - Get the formatted address, which resolves to \"Place Name, State, Country\" in the United States region (for example, \"Kirkland, WA, USA\").\n - Get other useful data such as photos.\n\nUse the Geocoding API\n\n- The [Geocoding API](/maps/documentation/geocoding) lets you\n convert an address, latitude and longitude coordinates, or place ID into\n geographic coordinates, and vice-versa. The following uses combine well with\n data-driven styling for boundaries:\n\n - Use Geocoding to get the viewport for a region.\n - Apply component filtering to your Geocoding call to get the place IDs for administrative areas 1-4, locality, or postal code.\n - Use reverse geocoding to find place IDs by latitude and longitude coordinates, or even return place IDs for all components in a particular location.\n\n The following example uses an address (url-escaped) to make a request to the\n Geocoding API: \n\n ```html\n https://maps.googleapis.com/maps/api/geocode/json?latlng=41.864182,-87.676930&key=YOUR_API_KEY\n ```\n\n You can use [reverse\n geocoding](/maps/documentation/geocoding/requests-reverse-geocoding) to\n find place IDs. The following example Geocoding service function returns the\n place IDs for all address components at the specified latitude and longitude\n coordinates: \n\n ```html\n https://maps.googleapis.com/maps/api/geocode/json?latlng=41.864182,-87.676930&result_type=locality&key=YOUR_API_KEY\n ```\n\n Use reverse geocoding with component filtering to get the address component\n for one or more of the following types at the specified location:\n - `administrativeArea`\n - `country`\n - `locality`\n - `postalCode`\n - `schoolDistrict`\n\n The following example shows using the Geocoding service, adding component\n restrictions with reverse geocoding to retrieve all address components\n at the specified location for the `locality` type: \n\n ```html\n https://maps.googleapis.com/maps/api/geocode/json?latlng=41.864182,-87.676930&result_type=locality&key=YOUR_API_KEY\n ```"]]
