Question

您好我正在使用mkreversegeocoder查找用户当前的城市。它有效，但当我在另一个地方尝试它时，它给出了我所在国家（土耳其）的自治市/区的名称。例如，它给出了“伊斯坦布尔”的正确但是那里在我的国家是没有像“susurluk”这样的城市名称它是一个区。任何想法为什么它返回我的区而不是城市名？如果你想我会发布我的代码

  -(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] initWithCoordinate: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];
