I am trying to get current location of user using CLLocationCoordinate2D. I want the values in the format like

CLLocationCoordinate2D start = {-28.078694,153.382844 };

So that I can use them like following:

 NSString *urlAddress = [NSString 
       stringWithFormat:@"http://maps.google.com/?saddr=%1.6f,%1.6f&daddr=%1.6f,%1.6f",  
       start.latitude, start.longitude, 
       destination.latitude, destination.longitude];  

I used

CLLocation *location = [[CLLocation alloc]init ];
CLLocationDegrees currentLatitude = location.coordinate.latitude;
CLLocationDegrees currentLongitude = location.coordinate.longitude;

to get current lat & long.

But I am getting 0.000 for both when I try to test. I am testing on iPhone 4s.

If there is any sample code, it will be great.
