Answer 1

for zoom in

-(void)zoomInMap
{
region.span.latitudeDelta = region.span.latitudeDelta/2 ;
    region.span.longitudeDelta = region.span.longitudeDelta/2;



    region.center.latitude = mapView.centerCoordinate.latitude ;
    region.center.longitude = mapView.centerCoordinate.longitude ;
    [mapView setRegion:region animated:YES];
}

similarly for zoom out.
