Places SDK for iOS supports Place Autocomplete (Legacy) . If you are familiar with Place Autocomplete (Legacy), Place Autocomplete (New) makes the following changes:
-
Uses a new pricing model. For pricing information for all APIs, see Pricing for the Places SDK for iOS (New) .
-
To make a request, call the new
GMSPlacesClient fetchAutocompleteSuggestionsFromRequest:method. -
Pass to the request:
-
An instance of the new
GMSAutocompleteRequestclass that defines all request parameters, such as the query and session token. -
A callback of type
GMSAutocompleteSuggestionsCallbackto handle the response.
-
-
The
GMSAutocompleteFilterclass now lets you:- Set the region code used to determine formatting of the results.
- Set the prediction offset, a zero-based Unicode character offset of the query.
-
The response is defined by the new
GMSAutocompleteSuggestionclass. This class contains an array of instances of the new typeGMSAutocompletePlaceSuggestionrepresenting the suggestions. -
The session now concludes with a call to either Place Details (New) or Address Validation . For more information, see Autocomplete (New) and session pricing .
