I aktuellen Standort Namen von Breiten- und Längengrad,Erhalten Ortsnamen von Breite und Länge in iOS
Hier ist mein Code-Schnipsel Ich habe versucht, finden wollen, aber mein Protokoll zeigt Null-Wert in allen Orten, außer in placemark, placemark.ISOcountryCode und placemark.country
Ich möchte Wert von placemark.locality und placemark.subLocality aber es zeigt Nullwerte.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// this creates the CCLocationManager that will find your current location
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters;
[locationManager startUpdatingLocation];
}
// this delegate is called when the app successfully finds your current location
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:locationManager.location
completionHandler:^(NSArray *placemarks, NSError *error) {
NSLog(@"reverseGeocodeLocation:completionHandler: Completion Handler called!");
if (error){
NSLog(@"Geocode failed with error: %@", error);
return;
}
NSLog(@"placemarks=%@",[placemarks objectAtIndex:0]);
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);
}];
}
// this delegate method is called if an error occurs in locating your current location
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(@"locationManager:%@ didFailWithError:%@", manager, error);
}
Dank Im Voraus.
EDIT:

Sie müssen eine API von Drittanbietern wie 'Google Places API' verwenden. –
Sie müssen den kostenpflichtigen Google-Dienst nicht verwenden. Diese Funktionalität ist in iOS integriert. Sehen Sie sich CLLocation und CLPlacemark an. Es bietet Ihnen eine beliebige Granularität, die Sie von Coords erwarten, z. Land, Stadt, Region, Zeitzone, usw. etc. – samiles
