{
[super viewDidLoad];
map_view.delegate = self;
map_view.mapType = MKMapTypeStandard;
[self zoom_out_view];
}
- (void)zoom_out_view
{
// step.1 create co-ordianate-span as follows
MKCoordinateSpan span = {.latitudeDelta = 180, .longitudeDelta = 360};
// step.2 crate region as follows
MKCoordinateRegion region = MKCoordinateRegionMake(CLLocationCoordinate2DMake(0.0000f, 0.0000f), span);
// step.3 zoom using region to map as follows
[map_view setRegion:region animated:YES];
