ios - CLLocationManager，如何获取城市或州的全名

Question

我在我的 iPad 应用程序中使用 CLLocationManager 类来获取当前位置。

我正在使用下面的代码获取地址详细信息，

- (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如下详细信息:

                       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 给出城市名称，但不像北卡罗来纳州那样仅提供全名 NC。

当我的客户在美国使用应用程序时，他们得到的不是像“北卡罗来纳”这样的全名，而是 NC，Saint Charles 得到的是 St. Charles ETC。

有什么办法可以得到全名吗？

以下代码将所有详细信息返回到 CLPlacemark 中。

- (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);

                       }
                   }];
}

希望这对您有帮助。
