Delegate methods of MKMapView ?

Firstly you have added the storeKit.framework in your xcode project then define the protocol as <MKMapviewDelegate> in .h file.

- (void)mapView:(MKMapView *)mapView regionWillChangeAnimated:(BOOL)animated;

- (void)mapView:(MKMapView *)mapView regionDidChangeAnimated:(BOOL)animated;

- (void)mapViewWillStartLoadingMap:(MKMapView *)mapView;

- (void)mapViewDidFinishLoadingMap:(MKMapView *)mapView;

- (void)mapViewDidFailLoadingMap:(MKMapView *)mapView withError:(NSError *)error;

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation;

- (void)mapView:(MKMapView *)mapView didAddAnnotationViews:(NSArray *)views;
