Reverse Geocoding issues for City name in iOS - ipad

Question

I'm able to retrieve the current location in my iPad application using,
CLLocation *location = [[CLLocation alloc] initWithLatitude:[latitude floatValue] longitude:[longitude floatValue]];
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error)
{
NSLog(#"-----------------Placemark is %#-----------------", placemarks);
locationLabel.text = placemarks;
}];
and the output is,
-----------------Placemark is ("South Atlantic Ocean, South Atlantic Ocean #<-42.60533670,-21.93128480> +/- 100.00m, region (identifier <-41.51023865,-31.60774370> radius 4954476.31) <-41.51023865,-31.60774370> radius 4954476.31m"
)-----------------
Can I use the same information to just get the city and the country name? instead of the long list of information?
also, the 'locationLabel.text = placemarks' gives a warning, "Incompatible pointer types assigning to 'NSString*' from 'NSArray*_strong', which I'm unable to resolve.

Answer 1

Yes you can.
But you doing it a little it wrong. First of all, placemarks is an array and not a string. That's why locationLabel.text = placemarks gives a warning.
Placemarks is an array of CLPlacemarks. This is because the geocoder could return multiple results for a coordinate. In the simplest condition the first item in it should be okay.
A CLPlacemark has the property addressDictionary which contains the data of this location.
You can access this data with the address property constans defined by the ABPerson header file.
For example:
Get the first placemark from the array:
CLPlacemark *place = [placemarks objectAtIndex:0];
then get the city from this placemark:
NSString *cityName = [place objectForKey: kABPersonAddressCityKey];
Don't forget to import the AVPerson header!

Answer 2

your can get all following place details
placeNameLabel.text = [placemarks[0] name];
addressNumberLabel.text = [placemarks[0] subThoroughfare];
addressLabel.text = [placemarks[0] thoroughfare];
neighborhoodLabel.text = [placemarks[0] subLocality];
cityLabel.text = [placemarks[0] locality];
countyLabel.text = [placemarks[0] subAdministrativeArea];
stateLabel.text = [placemarks[0] administrativeArea];
zipCodeLabel.text = [placemarks[0] postalCode];
countryLabel.text = [placemarks[0] country];
countryCodeLabel.text = [placemarks[0] ISOcountryCode];
inlandWaterLabel.text = [placemarks[0] inlandWater];
oceanLabel.text = [placemarks[0] ocean];
