Converting a CLLocation object to CLLocationCoordinate2D in Xcode
Wednesday, January 9th, 2013 at
4:14 pm
We can convert a CLLocation object to a CLLocationCoordinate2D object using the coordinate property of the CLLocation object. This can be done as follows :
Consider a CLLocation object name myLocation. Now we can get the equivalent CLLocationCoordinate2D of myLocation as,
CLLocationCoordinate2D myCoordinate = myLocation.coordinate;
We can obtain the latitude and longitude of a CLLocationCoordinate2D object using its latitude and longitude properties.
i.e.,
double myLatitude = myCoordinate.latitude; // this will give the latitude value of the coordinate
double myLongitude = myCoordinate.longitude;// this will give the longitude value of the coordinate
