MKReverseGeocoder returns cities that are not a city?

Hi i am using mkreversegeocoder to find the users current city.It works but when i try it in another location it gives the names of borough/district in my country (Turkey).For example it gives "istanbul" correct but there is no city name like "susurluk" in my country it is a district.Any idea why it returns me districts instead of city name? if you want i would post my code's

  -(void)viewDidLoad {
[super viewDidLoad];


manager=[[CLLocationManager alloc]init];
manager.delegate=self;
manager.desiredAccuracy=kCLLocationAccuracyBest;

[manager startUpdatingLocation];

}

-(void)locationManager:(CLLocationManager *)aManager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {


    MKReverseGeocoder *geocoder=[[MKReverseGeocoder alloc] initWithC开发者_如何学JAVAoordinate:newLocation.coordinate];
    geocoder.delegate=self;
    [geocoder start];

    [manager startUpdatingLocation];

}

-(void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark {

NSDictionary * addressDict= [placemark addressDictionary];

//NSString *country = [addressDict objectForKey:@"Country"];

NSString *city = [addressDict objectForKey:@"City"];

//change the country name into en_US

NSLocale *locale = [NSLocale currentLocale];
NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];

NSLocale *usLocale = [[[NSLocale alloc] initWithLocaleIdentifier:@"en_US"] autorelease];

NSString *country1 = [usLocale displayNameForKey: NSLocaleCountryCode value: countryCode];

[[NSUserDefaults standardUserDefaults] setObject:country1 forKey:@"country"];
[[NSUserDefaults standardUserDefaults] setObject:city forKey:@"city"];

[[NSUserDefaults standardUserDefaults] synchronize];

}

You can get the correct answer by using the google map api in which you have to send the lat/long of the place and you will get answer in the form of json/xml. Please check out this question
