Goal c, how to get landmarks for coordinate data

Question

I have a question related to reverse geocoding.

In my application, I have some coordinates (not my current coordinates), and I want to convert them to labels. I dug a lot of sites and codes, but they all relate to reverse geocoding the current location ...

Is there a way to get labels for specific coordinates (which are not the current location)?

And if there is, please help me with some code or links.

You can achieve this in two ways: -

The first way: - Get information using google api

-(void)findAddresstoCorrespondinglocation
{
    NSString *str = [NSString stringWithFormat:@"http://maps.googleapis.com/maps/api/geocode/json?latlng=%f,%f&sensor=false",myCoordInfo.latitude,myCoordInfo.longitude];
    NSURL *url = [NSURL URLWithString:[str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
    ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:url] autorelease];
    [request setRequestMethod:@"GET"];
    [request setDelegate:self];
    [request setDidFinishSelector: @selector(mapAddressResponse:)];
    [request setDidFailSelector: @selector(mapAddressResponseFailed:)];
    [networkQueue addOperation: request];
    [networkQueue go];

}

In response, you will receive all the information about the location coordinates that you provided.

Second approach: -

a.) mapkit framework

b.) MKReverseGeocoder .h

MKReverseGeocoder *reverseGeocoder;

c.) .m

self.reverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:cordInfo];
    reverseGeocoder.delegate = self;
    [reverseGeocoder start];

MKReverseGeocoder

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{
    NSLog(@"MKReverseGeocoder has failed.");
}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{
    MKPlacemark * myPlacemark = placemark;
    NSString *city = myPlacemark.thoroughfare;
    NSString *subThrough=myPlacemark.subThoroughfare;
    NSString *locality=myPlacemark.locality;
    NSString *subLocality=myPlacemark.subLocality;
    NSString *adminisArea=myPlacemark.administrativeArea;
    NSString *subAdminArea=myPlacemark.subAdministrativeArea;
    NSString *postalCode=myPlacemark.postalCode;
    NSString *country=myPlacemark.country;
    NSString *countryCode=myPlacemark.countryCode;
    NSLog(@"city%@",city);
    NSLog(@"subThrough%@",subThrough);
    NSLog(@"locality%@",locality);
    NSLog(@"subLocality%@",subLocality);
    NSLog(@"adminisArea%@",adminisArea);
    NSLog(@"subAdminArea%@",subAdminArea);
    NSLog(@"postalCode%@",postalCode);
    NSLog(@"country%@",country);
    NSLog(@"countryCode%@",countryCode);

    }
