Question

I have tried this codes for getting the geolocation based values but not able to get the city name. How do I get the city name?
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
double lati = newLocation.coordinate.latitude;
_geo_coder_latitude_lbl.text= [[NSString stringWithFormat:#"%f",lati] retain];
_geocoder_latitude_str=_geo_coder_latitude_lbl.text;
NSLog(#"print lat;%#",_geocoder_latitude_str);
double longi = newLocation.coordinate.longitude;
_geocoder_longitude_lbl.text= [[NSString stringWithFormat:#"%f",longi] retain];
_geocoder_longitude_str=_geocoder_longitude_lbl.text;
NSLog(#"print lat;%#",_geocoder_longitude_str);
[self._geocoder reverseGeocodeLocation: locationManager.location completionHandler:
^(NSArray *placemarks, NSError *error)
{
//Get address
CLPlacemark *placemark = [placemarks objectAtIndex:0];
NSLog(#"Placemark array: %#",placemark.addressDictionary );
//String to address
_located_address = [[placemark.addressDictionary valueForKey:#"FormattedAddressLines"] componentsJoinedByString:#", "];
//Print the location in the console
NSLog(#"Currently address is: %#",_located_address);
// _ex_map_address_lbl.text=_located_address;
}];
[self _storeList_json_parser];
}

See the CLPlacemark docs, [CLPlacemark locatity] will return the city name associated with the placemark.
Check this sample code:
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
double lati = 45.46433;
double longi = 9.18839;
CLLocation *location = [[CLLocation alloc] initWithCoordinate:CLLocationCoordinate2DMake(lati, longi)
altitude:0
horizontalAccuracy:0
verticalAccuracy:0
timestamp:[NSDate date]];
[geocoder reverseGeocodeLocation:location completionHandler:
^(NSArray *placemarks, NSError *error)
{
CLPlacemark *placemark = [placemarks lastObject];
if (error || !placemark)
return;
NSString *city = placemark.locality;
if (!city)
city = placemark.subAdministrativeArea;
NSLog(#"City for location: %#", city);
}];
