ios - 将 GMSAutocompleteViewController 设置为仅指定特定状态

Question

当我单击 GMSAutocompleteViewController 时，它应该只显示建议中的所有状态。我不想要这个领域的城市、国家或其他任何东西。那么这可能吗？

您无法直接过滤状态，Google Auto Complete API 提供了一些过滤器及其预定义的 ENUMS。

let autocompleteController = GMSAutocompleteViewController()
autocompleteController.delegate = self

// Set a filter to return only addresses.
let filter = GMSAutocompleteFilter()
filter.type = .address
autocompleteController.autocompleteFilter = filter

present(autocompleteController, animated: true, completion: nil)

GMSAutocompleteFilter.h : ENUMS description below

typedef NS_ENUM(NSInteger, GMSPlacesAutocompleteTypeFilter) {
  /**
   * All results.
   */
  kGMSPlacesAutocompleteTypeFilterNoFilter,
  /**
   * Geeocoding results, as opposed to business results.
   */
  kGMSPlacesAutocompleteTypeFilterGeocode,
  /**
   * Geocoding results with a precise address.
   */
  kGMSPlacesAutocompleteTypeFilterAddress,
  /**
   * Business results.
   */
  kGMSPlacesAutocompleteTypeFilterEstablishment,
  /**
   * Results that match the following types:
   * "locality",
   * "sublocality"
   * "postal_code",
   * "country",
   * "administrative_area_level_1",
   * "administrative_area_level_2"
   */
  kGMSPlacesAutocompleteTypeFilterRegion,
  /**
   * Results that match the following types:
   * "locality",
   * "administrative_area_level_3"
   */
  kGMSPlacesAutocompleteTypeFilterCity,
};
