CLLocationCoordinate2D newCoordinate = newLocation.coordinate;
CLLocationCoordinate2D oldCoordinate = oldLocation.coordinate;
if (newCoordinate.latitude == oldCoordinate.latitude && newCoordinate.longitude == oldCoordinate.longitude) return;
float distance = [newLocation distanceFromLocation:oldLocation];
if (distance < distanceFilter) {
//send to server
