How we can convert the Longitude and Latitude in points - ios

Question

I m working to get the Longitude and Latitude for current place and i m using the code
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;
lat = [NSString stringWithFormat:#"%d° %d' %1.4f\"",
degrees, minutes, seconds];
NSLog(#" Current Latitude : %#",lat);
degrees = newLocation.coordinate.longitude;
decimal = fabs(newLocation.coordinate.longitude - degrees);
minutes = decimal * 60;
seconds = decimal * 3600 - minutes * 60;
// longt = [NSString stringWithFormat:#"%d° %d' %1.4f\"",
// degrees, minutes, seconds];
longt = [NSString stringWithFormat:#"%d° %d' %1.4f\"",
degrees, minutes, seconds];
NSLog(#" Current Longitude : %#",longt);
}
and getting the:
Current Latitude : 37° 47' 9.0024"
Current Longitude : -122° 24' 23.1012"
But i want the Latitude and Longitude like that 13.233233 (mean in points). So how i can convert this in Longitude and Latitude in point ?Please help.

Answer 1

From the following answer Converting from longitude\latitude to Cartesian coordinates
x = R * cos(lat) * cos(lon)
y = R * cos(lat) * sin(lon)
z = R *sin(lat)
Where R is the approximate radius of earth (e.g. 6371KM).

Answer 2

In newLocation.coordinate.latitude and newLocation.coordinate.longitude, you have the values you want, just don't convert them.

Answer 3

why are you using this depreciated method use this method for getting location in iOS 7. Use this method
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
// location_updated = [locations lastObject];
// NSLog(#"updated coordinate are %#",location_updated);
float currentLocationLati = [[locations objectAtIndex:0] coordinate].latitude;
float currentLocationLong = [[locations objectAtIndex:0] coordinate].longitude;
}
By this methods you will find update latitude and longitude just use them don't convert them into degree
