This is the moveable map code like ola and uber. Means when i move the map, at that time the map pin is noted, the noted pin is given me address of the that particular area like city, state, pincode etc in label, but i want only the longitude, latitude value of this address in label.
so please help me about this code. How can i get the longitude latitude value in ?

Answer 1

Assuming that the label that you want to is self.addresslbl, change this method:
-(void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
CLLocation *location = [[CLLocation alloc]initWithLatitude:mapView.centerCoordinate.latitude longitude:mapView.centerCoordinate.longitude];
[self geocode:location];
}
To:
-(void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
self.addresslbl.text = [NSString stringWithFormat:#"%f, %f", mapView.centerCoordinate.longitude, mapView.centerCoordinate.latitude];
}
