Umgekehrte Geocodierung
Entwickler im Europäischen Wirtschaftsraum (EWR)
Die umgekehrte Geocodierung bezieht sich auf die Umwandlung geografischer Koordinaten eines Standorts in eine visuell lesbare Adresse. Das Maps SDK for iOS enthält die Klasse GMSGeocoder, die die Memberfunktion reverseGeocodeCoordinate enthält, mit der Sie die Konvertierung durchführen können. Diese Methode verwendet Standortkoordinaten in einer Instanz eines CLLocationCoordinate2D-Objekts und gibt eine für Menschen lesbare Straßenadresse in einer Instanz der Klasse GMSAddress zurück.
Einfluss von Spracheinstellungen
Der Geocoder ist für die Bereitstellung von lesbaren Adressen optimiert. Dazu werden Straßenadressen in der lokalen Sprache zurückgegeben, die bei Bedarf in für den Nutzer lesbaren Text transliteriert werden. Alle anderen Adressen werden in der bevorzugten Sprache zurückgegeben.
Adresskomponenten werden in derselben Sprache zurückgegeben, die anhand der ersten Komponente ausgewählt wird.
Wenn ein Name in der bevorzugten Sprache nicht verfügbar ist, wird die nächstgelegene Übereinstimmung verwendet.
Garantien in Bezug auf Adresskomponenten
Google übernimmt keine Garantie für Adresskomponenten. Die Adressstruktur ändert sich von Land zu Land und sogar innerhalb von Ländern.
Adresskomponenten enthalten nur das, was für Postadressen relevant ist, und wenig mehr.
Insbesondere ist locality nicht immer vorhanden und soll auch nicht immer die city darstellen.

The Maps SDK for iOS\nincludes a class called the\n[`GMSGeocoder`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSGeocoder)\nclass, which includes the\n[`reverseGeocodeCoordinate`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSGeocoder#-reversegeocodecoordinate:completionhandler:)\nmember function which you can use to perform the conversion. This method takes\nlocation coordinates in an instance of a\n[CLLocationCoordinate2D](https://developer.apple.com/documentation/corelocation/cllocationcoordinate2d?language=objc)\nobject, and returns a human-readable street address in an instance of the\n[`GMSAddress`](/maps/documentation/ios-sdk/reference/objc/Classes/GMSAddress)\nclass.\n| **Note:** The Maps SDK for iOS does not directly support Geocoding. We recommend that applications use the [Geocoding API](/maps/documentation/geocoding) directly to convert human-readable addresses to map coordinates.\n\nThe influence of language preferences\n\nThe geocoder is optimized to provide human readable street addresses. To achieve\nthis, it returns street addresses in the local language, transliterated to text\nthat is readable by the user (if necessary). All other addresses are returned in\nthe preferred language.\n\n- Address components are returned in the same language, which is chosen from the\n first component.\n\n- If a name is not available in the preferred language, then the geocoder uses\n the closest match.\n\nGuarantees regarding address components\n\nGoogle makes no guarantee regarding address components. Address structure\nchanges from country to country, and even within countries.\n\n- You can expect address components to contain only what is relevant for postal\n addresses, and little more.\n\n- In particular, *locality* is neither guaranteed to be always present, nor is\n it supposed to always represent the *city*.\n\nFor an example of address components in action, see\n[Place Autocomplete Address Form](/maps/documentation/javascript/examples/places-autocomplete-addressform).\n\nSorting the results\n\nResults aren't sorted by distance, and the order is subject to change.\n\n- A particular order is not guaranteed.\n\n- There is no guarantee about what the first result will be.\n\nReverse geocoding is an estimate\n\nThe geocoder attempts to find the closest addressable location within a\nparticular tolerance.\n\nIf the geocoder can't find a match, then it returns no results.\n\nFor more information, see\n[Geocoding Addresses Best Practices](/maps/documentation/geocoding/best-practices)\nand also the [Geocoding FAQ](/maps/documentation/geocoding/faq)."]]
