Thanks in advance...

-(MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:
(id <MKAnnotation>)annotation {
    MKPinAnnotationView *pinView = nil; 
    if(annotation != mapView.userLocation) 
    {
        static NSString *defaultPinID = @"com.invasivecode.pin";
        pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
        if ( pinView == nil ) pinView = [[[MKPinAnnotationView alloc]
                                          initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];

        pinView.pinColor = MKPinAnnotationColorRed; 
        pinView.canShowCallout = YES;
        pinView.animatesDrop = YES;
    } 
    else {
        [mapView.userLocation setTitle:@"I am here"];
    }
    return pinView;
}

    places = [[NSMutableArray alloc] init];
    Place *aPlace1 = [Place alloc];
    aPlace.title = @"xyz";
    aPlace.subtitle = @"xyz ";

    CLLocationCoordinate2D crd1;
    crd1.latitude = ;
    crd1.longitude = ;

    [aPlace1 addCoordinates:crd1];
    [places addObject:aPlace1];
    [aPlace1 release];
    aPlace1 = nil;

    /*
     Object having address of office 2
     */
    Place *aPlace2 = [Place alloc];
    aPlace2.title = @"xyz";
    aPlace2.subtitle = @"xyz ";
    CLLocationCoordinate2D crd2;
    crd2.latitude = ;
    crd2.longitude = ;
    [aPlace2 addCoordinates:crd2];

    CLLocationCoordinate2D centreCarte;
    centreCarte.latitude = ;

    MKCoordinateSpan zoom;

    zoom.latitudeDelta = 2;
    zoom.longitudeDelta = zoom.latitudeDelta;

If you don't show the "Google logo", your app will be rejected. The default logo is shown in southwest position in the map.

Use this:

- (UIImageView*) googleLogo {

    UIImageView *imgView = nil;
    for (UIView *subview in self.subviews) {
        if ([subview isMemberOfClass:[UIImageView class]]) {
            imgView = (UIImageView*)subview;
            break;
        }
    }
    return imgView;
}

@end

to change the google logo position this is the snippet:

- (void) alignGoogleLogo:(UITextAlignment) alignment {

  UIImageView *logo = [self googleLogo];
  CGRect frame = logo.frame;
  float padding = 9;

  if (alignment == UITextAlignmentLeft) {

    frame.origin.x = padding;

  } else if (alignment == UITextAlignmentCenter) {

    frame.origin.x = (self.size.width / 2) - (frame.size.width / 2);

  } else if (alignment == UITextAlignmentRight) {

    frame.origin.x = self.size.width - frame.size.width - padding;
  }

  [logo setFrame:frame];

}
