获取当前位置的邮政编码 - iPhone SDK

Question

如何使用mapkit获取当前位置的邮政编码,我没有找到任何用于获取此文档的API.我使用了CLLocationManager的坐标,attitue,水平,垂直,航向和速度参数,但未能获得邮政编码.

任何人都可以给我API或示例代码来完成它.

是否可以使用iPhone中的当前位置获取邮政编码？

Answer 1

iPhone中的反向地理编码:

首先添加<MobileCoreServices/MobileCoreServices.h>框架.

-(void)CurrentLocationIdentifier
    {
        //---- For getting current gps location
        CLLocationManager *locationManager;
        CLLocation *currentLocation;

        locationManager = [CLLocationManager new];
        locationManager.delegate = self;
        locationManager.distanceFilter = kCLDistanceFilterNone;
        locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        [locationManager startUpdatingLocation];
    }

使用GPS位置获取地点详细信息的反向地理编码.

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    currentLocation = [locations objectAtIndex:0];
    [locationManager stopUpdatingLocation];

    CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
    [geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if (!(error))
         {
             CLPlacemark *placemark = [placemarks objectAtIndex:0];
            NSLog(@"\nCurrent Location Detected\n");
             NSLog(@"placemark %@",placemark);
             NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];

             NSString *Address = [[NSString alloc]initWithString:locatedAt];
             NSString *Zipcode = [[NSString alloc]initWithString:placemark.postalCode];
             NSLog(@"%@",Zipcode);      
         }
         else
         {
             NSLog(@"Geocode failed with error %@", error); // Error handling must required
         }
     }];
}

 placemark.region
 placemark.country
 placemark.locality
 placemark.name
 placemark.ocean
 placemark.postalCode
 placemark.subLocality
 placemark.location

您可以使用纬度和经度创建一个MKPlacemark 对象，其中包含邮政编码。
