Easiest way of getting reverse geocoded current location from iOS
提问by kamziro
I saw from another question here : Determine iPhone user's countrythat it is possible to get the current country the user of the iPhone is in.
我从这里的另一个问题中看到：确定 iPhone 用户所在的国家/地区，可以获取iPhone 用户所在的当前国家/地区。
And that is quite convenient for many uses. However, would it be possible to go even deeper and infer from iOS (if it has the information) which state or city the user is in as well?
这对于许多用途来说非常方便。但是，是否可以更深入地从 iOS（如果有信息）推断用户所在的州或城市？
I suppose reverse geocoding services would be the next step if things weren't possible.. Are there even such things as a reverse geocoding service you can hire for your app though?
我想如果不可能的话，反向地理编码服务将是下一步。不过，是否有诸如反向地理编码服务之类的东西可以为您的应用程序租用？

I would start with the CLReverseGeocoderclass.
我会从CLReverseGeocoder课堂开始。
This stackoverflow questiongets the current city and can probably be adapted for your use.

MKReverseGeocoderis deprecated in iOS 5, now it's CLGeocoder
MKReverseGeocoder在 iOS 5 中已弃用，现在是 CLGeocoder
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
[self.locationManager stopUpdatingLocation];
CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
[geoCoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
for (CLPlacemark * placemark in placemarks) {
.... = [placemark locality];
}
}];
}

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
CLLocation *newLocation = [[CLLocation alloc]initWithLatitude:21.1700
longitude:72.8300];
[geocoder reverseGeocodeLocation:newLocation
completionHandler:^(NSArray *placemarks, NSError *error) {
if (error) {
NSLog(@"Geocode failed with error: %@", error);
return;
}
if (placemarks && placemarks.count > 0)
{
CLPlacemark *placemark = placemarks[0];
NSDictionary *addressDictionary =
placemark.addressDictionary;
NSLog(@"%@ ", addressDictionary);
NSString *address = [addressDictionary
objectForKey:(NSString *)kABPersonAddressStreetKey];
NSString *city = [addressDictionary
objectForKey:(NSString *)kABPersonAddressCityKey];
NSString *state = [addressDictionary
objectForKey:(NSString *)kABPersonAddressStateKey];
NSString *zip = [addressDictionary
objectForKey:(NSString *)kABPersonAddressZIPKey];
NSLog(@"%@ %@ %@ %@", address,city, state, zip);
}
}];
Result
结果
{
City = Surat;
Country = India;
CountryCode = IN;
FormattedAddressLines = (
Surat,
Gujarat,
India
);
Name = Surat;
State = Gujarat;
}
2012-12-20 21:33:26.284 CurAddress[4110:11603] (null) Surat Gujarat (null)

[geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
if(placemarks.count){
placeNameLabel.text = [placemarks[0] name];
streetNumberLabel.text = [placemarks[0] subThoroughfare];
streetLabel.text = [placemarks[0] thoroughfare];
neighborhoodLabel.text = [placemarks[0] subLocality];
cityLabel.text = [placemarks[0] locality];
countyLabel.text = [placemarks[0] subAdministrativeArea];
stateLabel.text = [placemarks[0] administrativeArea]; //or province
