Question

我正在获得纬度经度并在ios中进行反向地理编码。这是我到目前为止所做的。

-(void)GetLocationData
 {
if (self.locationManager == nil)
{
    self.locationManager = [[CLLocationManager alloc] init];
    self.locationManager.delegate = self;
}
else
{
    nil;
}

if ([self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])
{
    [self.locationManager requestWhenInUseAuthorization];
}
else
{
    nil;
}

self.locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;//kCLLocationAccuracyBest;
[self.locationManager startUpdatingLocation];
}



- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(@"didUpdateToLocation: %@", newLocation);
CLLocation *currentLocation = newLocation;
NSString *longitude;
NSString *latitude;

if (currentLocation != nil) {
    longitude = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.longitude];//
    latitude = [NSString stringWithFormat:@"%.8f", currentLocation.coordinate.latitude];//

    NSLog(@"Longitude-----%@-----Latitude----%@",longitude,latitude);
    dm.strLatitude=latitude;
    dm.strLongitude=longitude;
}

[self.locationManager stopUpdatingLocation];



geocoder = [[CLGeocoder alloc] init];
// Reverse Geocoding
NSLog(@"Resolving the Address");
CLLocationDegrees degreesLati=lati;
CLLocationDegrees degreesLongi=longi;
CLLocation *loc=[[CLLocation alloc] initWithLatitude:degreesLati longitude:degreesLongi];
[geocoder reverseGeocodeLocation:loc completionHandler:^(NSArray *placemarks, NSError *error) {
    NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
    if (error == nil && [placemarks count] > 0) {
        placemark = [placemarks objectAtIndex:[placemarks count]-1];

        NSString *address = [NSString stringWithFormat:@"%@ %@\n%@ %@\n%@\n%@",
                             placemark.subThoroughfare, placemark.thoroughfare,
                             placemark.postalCode, placemark.subLocality,
                             placemark.subAdministrativeArea,
                            placemark.country];

       // NSString *address=[self.placemark];

        NSDictionary *dictAddress = [NSDictionary dictionaryWithDictionary:placemark.addressDictionary];
        NSMutableDictionary *dictTxtData = [NSMutableDictionary dictionary];
        NSLog(@"country:%@",dictAddress);
        strCountry=placemark.country;

        NSLog(@"Address------%@",address);
    } else {
        NSLog(@"%@", error.debugDescription);
    }
} ];

}

但我的问题是在Android和iOS中为此返回2个不同的地址。但Android地址是正确的。这就是Android应用获取地址的方式。

{
      Geocoder geocoder = new Geocoder(context, Locale.ENGLISH);

      try {
           /**
           * Geocoder.getFromLocation - Returns an array of Addresses 
           * that are known to describe the area immediately   surrounding the given latitude and longitude.
           */
            List<Address> addresses = geocoder.getFromLocation(latitude, longitude, this.geocoderMaxResults);

           return addresses;
           } catch (IOException e) {
            //e.printStackTrace();
             Log.e(TAG, "Impossible to connect to Geocoder", e);
       }

}

反向地理编码

[geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error) {
    NSLog(@"Found placemarks: %@, error: %@", placemarks, error);
    if (error == nil && [placemarks count] > 0) {

        placemark = [placemarks objectAtIndex:[placemarks count]-1];

        NSString *address = [NSString stringWithFormat:@"%@ %@\n%@ %@\n%@\n%@",
                             placemark.subThoroughfare, placemark.thoroughfare,
                             placemark.postalCode, placemark.subLocality,
                             placemark.subAdministrativeArea,
                            placemark.country];

       // NSString *address=[self.placemark];

        NSDictionary *dictAddress = [NSDictionary dictionaryWithDictionary:placemark.addressDictionary];
        NSMutableDictionary *dictTxtData = [NSMutableDictionary dictionary];



        strCountry=placemark.country;

        NSLog(@"Address------%@",address);
    } else {
        NSLog(@"%@", error.debugDescription);
    }
} ];

我以这种方式currentLocation

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

Answer 1

我想猜一下!!

那些lati和longi是什么？不应该使用longitude和longitude来代替

CLLocationDegrees degreesLati = currentLocation.coordinate.longitude;
CLLocationDegrees degreesLongi = currentLocation.coordinate.latitude;

代替：

CLLocationDegrees degreesLati=lati;
CLLocationDegrees degreesLongi=longi;

反向地理编码返回错误的地址
