Geocodifica inversa
Sviluppatori dello Spazio economico europeo (SEE)
La geocodifica inversa si riferisce alla conversione delle coordinate geografiche di una località in un indirizzo stradale leggibile. Maps SDK for iOS
include una classe chiamata
GMSGeocoder
che include la funzione
membro reverseGeocodeCoordinate che puoi utilizzare per eseguire la conversione. Questo metodo accetta le coordinate della posizione in un'istanza di un oggetto CLLocationCoordinate2D e restituisce un indirizzo stradale leggibile in un'istanza della classe GMSAddress.
L'influenza delle preferenze di lingua
Il geocodificatore è ottimizzato per fornire indirizzi stradali leggibili. Per raggiungere
questo obiettivo, restituisce gli indirizzi stradali nella lingua locale, traslitterati in testo
leggibile dall'utente (se necessario). Tutti gli altri indirizzi vengono restituiti nella lingua preferita.
I componenti dell'indirizzo vengono restituiti nella stessa lingua, scelta dal
primo componente.
Se un nome non è disponibile nella lingua preferita, il geocoder utilizza
la corrispondenza più vicina.
Garanzie relative ai componenti dell'indirizzo
Google non fornisce alcuna garanzia in merito ai componenti dell'indirizzo. La struttura dell'indirizzo
varia da paese a paese e persino all'interno dei paesi.
Puoi aspettarti che i componenti dell'indirizzo contengano solo ciò che è pertinente per gli indirizzi postali e poco altro.
In particolare, non è garantito che locality sia sempre presente e non è previsto che rappresenti sempre la città.

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)."]]
