GMSAutocompleteResultsViewControllerDelegate

@protocol GMSAutocompleteResultsViewControllerDelegate <NSObject>

Protocol used by GMSAutocompleteResultsViewController, to communicate the user’s interaction with the controller to the application.

• -resultsController:didAutocompleteWithPlace:

  Called when a place has been selected from the available autocomplete predictions.

  Declaration

  Swift

  func resultsController(_ resultsController: GMSAutocompleteResultsViewController, didAutocompleteWith place: GMSPlace)

  Objective-C

  - (void)resultsController:
              (nonnull GMSAutocompleteResultsViewController *)resultsController
      didAutocompleteWithPlace:(nonnull GMSPlace *)place;

  Parameters

  resultsController	The GMSAutocompleteResultsViewController that generated the event.
  place	The GMSPlace that was returned.

• -resultsController:didFailAutocompleteWithError:

  Called when a non-retryable error occurred when retrieving autocomplete predictions or place details. A non-retryable error is defined as one that is unlikely to be fixed by immediately retrying the operation.

  Only the following values of GMSPlacesErrorCode are retryable:

  • kGMSPlacesNetworkError
  • kGMSPlacesServerError
  • kGMSPlacesInternalError

  All other error codes are non-retryable.

  Declaration

  Swift

  func resultsController(_ resultsController: GMSAutocompleteResultsViewController, didFailAutocompleteWithError error: any Error)

  Objective-C

  - (void)resultsController:
              (nonnull GMSAutocompleteResultsViewController *)resultsController
      didFailAutocompleteWithError:(nonnull NSError *)error;

  Parameters

  resultsController	The GMSAutocompleteResultsViewController that generated the event.
  error	The NSError that was returned.

• -resultsController:didSelectPrediction:

  Called when the user selects an autocomplete prediction from the list but before requesting place details. Returning NO from this method will suppress the place details fetch and didAutocompleteWithPlace will not be called.

  Objective-C

  - (BOOL)resultsController:
