CLLocationManager,如何获取城市或州的全名

Question

我在我的iPad App中使用CLLocationManager类来获取当前位置.

我使用下面的代码来获取地址详细信息,

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
    NSUserDefaults *oIsLocation = [NSUserDefaults standardUserDefaults];
    if([oIsLocation boolForKey:@"IsLocation"])
    {
        NSTimeInterval locationAge = -[newLocation.timestamp timeIntervalSinceNow];
        if (locationAge > 5.0) return;

        if (newLocation.horizontalAccuracy < 0) return;

        if (bestEffortAtLocation == nil || bestEffortAtLocation.horizontalAccuracy > newLocation.horizontalAccuracy)
        {
            if(bestEffortAtLocation.coordinate.latitude != newLocation.coordinate.latitude && bestEffortAtLocation.coordinate.longitude != newLocation.coordinate.longitude)
            {
                [self saveLocation:newLocation];
                self.bestEffortAtLocation = newLocation;
                [self saveUserLocation];
            }
        }
    }
}

我正在进行反向地理编码以获取详细信息如下:

                       NSLog(@"placemark.ISOcountryCode %@",placemark.ISOcountryCode);
                       NSLog(@"placemark.country %@",placemark.country);
                       NSLog(@"placemark.postalCode %@",placemark.postalCode);
                       NSLog(@"placemark.administrativeArea %@",placemark.administrativeArea);
                       NSLog(@"placemark.locality %@",placemark.locality);
                       NSLog(@"placemark.subLocality %@",placemark.subLocality);
                       NSLog(@"placemark.subThoroughfare %@",placemark.subThoroughfare);

placemark.locality给出了城市名称,但没有全名,如北卡罗来纳州只有NC.

当我的客户在美国使用应用程序时,而不是像"北卡罗莱纳州"这样的全名,他们获得NC,圣查尔斯获得圣查尔斯等.

有没有办法获得全名？

以下代码将所有细节返回到CLPlacemark.

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

    CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
    [geoCoder reverseGeocodeLocation:newLocation
                   completionHandler:^(NSArray *placemarks, NSError *error) {
                       for (CLPlacemark *placemark in placemarks) {

                           NSLog(@"%@",[placemark locality]);

                           CLPlacemark *placemark = [placemarks objectAtIndex:0];

                           NSLog(@"placemark.ISOcountryCode %@",placemark.ISOcountryCode);
                           NSLog(@"placemark.country %@",placemark.country);
                           NSLog(@"placemark.postalCode %@",placemark.postalCode);
                           NSLog(@"placemark.administrativeArea %@",placemark.administrativeArea);
                           NSLog(@"placemark.locality %@",placemark.locality);
                           NSLog(@"placemark.subLocality %@",placemark.subLocality);
                           NSLog(@"placemark.subThoroughfare %@",placemark.subThoroughfare);

                       }
                   }];
}

愿这很有帮助.
