Wie bekomme ich Informationen über den Bundesstaat (des Landes) mit den Koordinaten des aktuellen Standorts?

Question

Wie erhalte ich Informationen über den Status von den Standortkoordinaten? Gibt es ein Drittanbieter-Framework oder eine API, die Staaten/Provinzen von lat-long-Werten zur Verfügung stellt?

Answer 1

Übergeben Sie den aktualisierten CLLocation-Wert in der nachstehenden Methode. Es gibt verschiedene Informationen, die Sie von CLPlacemark

-(void)getLocationDetails:(CLLocation *)location{ 
    CLGeocoder *reverseGeocoder = [[CLGeocoder alloc] init]; 
     [reverseGeocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error) { 
     CLPlacemark *myPlacemark = [placemarks objectAtIndex:0]; 
     NSString *countryCode = myPlacemark.ISOcountryCode; 
     NSString *countryName = myPlacemark.country; 
     NSString *cityName= myPlacemark.subAdministrativeArea; 
     NSLog(@"My country code: %@ and countryName: %@ MyCity: %@", countryCode, countryName, cityName); 
    }]; 
} 

Answer 2

Staat placemark.administrativeArea erhalten werden unter Verwendung erhalten können.

CLLocation *loc = [[CLLocation alloc]initWithLatitude:coordinate.latitude longitude:coordinate.longitude 
        ]; 
[ceo reverseGeocodeLocation:loc 
      completionHandler:^(NSArray *placemarks, NSError *error) { 
       CLPlacemark *placemark = [placemarks objectAtIndex:0]; 
       NSLog(@"placemark %@",placemark); 
       //String to hold address 
       NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "]; 
       NSLog(@"addressDictionary %@", placemark.addressDictionary); 

       NSLog(@"placemark %@",placemark.region); 
       NSLog(@"placemark %@",placemark.country); // Give Country Name 
       NSLog(@"placemark %@",placemark.locality); // Extract the city name 
       NSLog(@"location %@",placemark.name); 
       NSLog(@"location %@",placemark.ocean); 
       NSLog(@"location %@",placemark.postalCode); 
       NSLog(@"location %@",placemark.subLocality); 

       NSLog(@"location %@",placemark.location); 
       //Print the location to console 
       NSLog(@"I am currently at %@",locatedAt); 

       NSLog(@"state name %@",placemark.administrativeArea); 
       _City.text=[placemark.addressDictionary objectForKey:@"City"]; 
       [locationManager stopUpdatingLocation]; 
      } 

]; 
} 

Answer 3

Sie können es Reverse Geo-Code erhalten werden. Siehe untenstehendes Beispiel:

geocoder = [[CLGeocoder alloc] init]; 

//newlocation is CLLocation object you need to pass user location there. 

[geocoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) { 
     if (error == nil && [placemarks count] > 0) { 
      placemark = [placemarks lastObject]; 
      // placemark.administrativeArea is state of use 

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

Von CLPlacemark.h: // Placemark Wörterbuch enthalten andere Informationen des Benutzers wird wie unten angezeigt.
