@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.

Declaration

Swift

optional func resultsController(_ resultsController: GMSAutocompleteResultsViewController, didSelect prediction: GMSAutocompletePrediction) -> Bool

Objective-C

- (BOOL)resultsController:
            (nonnull GMSAutocompleteResultsViewController *)resultsController
      didSelectPrediction:(nonnull GMSAutocompletePrediction *)prediction;

Parameters

`resultsController`	The `GMSAutocompleteResultsViewController` that generated the event.
`prediction`	The `GMSAutocompletePrediction` that was selected.
