Хотя нажмите на аннотацию, вызовите этот метод и передать ваши координаты.

-(void)didSelectAnnotationAtCoordinate:(CLLocationCoordinate2D)coordinate 
{ 
    MKMapRect mapRect = [self.mapView visibleMapRect]; 
    MKMapPoint point = MKMapPointForCoordinate(coordinate); 
    mapRect.origin.x = point.x - mapRect.size.width * 0.3;//change value 
    mapRect.origin.y = point.y - mapRect.size.height * 0.70;//change value     
    [self.mapView setVisibleMapRect:mapRect animated:YES]; 
}
