how to get the current location in latitude and longitude in objective c

Question

I am using the following code to get the current location,I have added the corelocation framework

- (void)viewDidLoad {
    [super viewDidLoad];

    locationManager = [[CLLocationManager alloc] init];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
    locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
    [locationManager startUpdatingLocation];

}

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation
{
    int degrees = newLocation.coordinate.latitude;
    double decimal = fabs(newLocation.coordinate.latitude - degrees);
    int minutes = decimal * 60;
    double seconds = decimal * 3600 - minutes * 60;
    NSString *lat = [NSString stringWithFormat:@"%d° %d' %1.4f\"", 
                     degrees, minutes, seconds];
    NSLog(@" Current Latitude : %@",lat);
    //latLabel.text = lat;
    degrees = newLocation.coordinate.longitude;
    decimal = fabs(newLocation.coordinate.longitude - degrees);
    minutes = decimal * 60;
    seconds = decimal * 3600 - minutes * 60;
    NSString *longt = [NSString stringWithFormat:@"%d° %d' %1.4f\"", 
                       degrees, minutes, seconds];
    NSLog(@" Current Longitude : %@",longt);
    //longLabel.text = longt;
}

But i am getting the default values i.e, Latitude : 42° 17' 36.8898" and Longitude : -71° 27' 43.1003" where my current Latitude:N 12° 56' 11.5624" and Longitude:E 77° 32' 41.0834". How to get the exact latitude and longitude. where i am doing the mistake or do i need to add any other method or function or framework.

Thanks in Advance.

Answer 1

You can add this method where you need to get the current latitude and longitude:

-(CLLocationCoordinate2D) getLocation{
    CLLocationManager *locationManager = [[[CLLocationManager alloc] init] autorelease];
    locationManager.delegate = self;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    locationManager.distanceFilter = kCLDistanceFilterNone;
    [locationManager startUpdatingLocation];
    CLLocation *location = [locationManager location];
    CLLocationCoordinate2D coordinate = [location coordinate];

    return coordinate;
}

And to call it use:

CLLocationCoordinate2D coordinate = [self getLocation];
NSString *latitude = [NSString stringWithFormat:@"%f", coordinate.latitude];
NSString *longitude = [NSString stringWithFormat:@"%f", coordinate.longitude];

NSLog(@"*dLatitude : %@", latitude);
NSLog(@"*dLongitude : %@",longitude);

Test the application on real device. The Simulator will always show you the default value for Latitude and Longitude. Also make sure that the location services are enabled on your device.
