# MKReverseGeocoderDelegate Defines the interface for receiving messages from an [`MKReverseGeocoder`](/documentation/MapKit/MKReverseGeocoder) object. ``` @protocol MKReverseGeocoderDelegate ``` ## Overview You use this protocol to receive the placemark information for a given coordinate or to retrieve any errors that occurred during the reverse-geocoding process. Delegates must implement both methods of this protocol. The Google terms of service require that the reverse geocoding service be used in conjunction with a Google map; take this into account when designing your application’s user interface. Each Map Kit application has a limited amount of reverse geocoding capacity, so it is to your advantage to use reverse geocode requests sparingly. For more information about when to initiate reverse-geocoding requests, see [`MKReverseGeocoder`](/documentation/MapKit/MKReverseGeocoder). This protocol is deprecated in iOS 5.0. Use the class instead. ## Topics ### Processing placemark searches [`reverseGeocoder:didFindPlacemark:`](/documentation/MapKit/MKReverseGeocoderDelegate/reverseGeocoder:didFindPlacemark:) Tells the delegate that a reverse geocoder successfully obtained placemark information for its coordinate. [`reverseGeocoder:didFailWithError:`](/documentation/MapKit/MKReverseGeocoderDelegate/reverseGeocoder:didFailWithError:) Tells the delegate that the specified reverse geocoder failed to obtain information about its coordinate. --- Copyright © 2026 Apple Inc.
