How we can convert the Longitude and Latitude in points

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.

In Cartesian coordinates of what coordinate system? The UIView or the MKMapView? What's the purpose? If you just want to display them in decimal format, do `NSLog(@"lat,long = %f,%f", newLocation.coordinate.latitude, newLocation.coordinate.longitude);`. Also, this is not an "android-mapview". — , May 29 '14 at 13:11

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

this is an array of updated location, I update my answer you can get latitude and longitude in float from there – Gajendra Rawat May 29 '14 at 13:18

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).

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