show users location blue point in iPhone MKMapView

I am developing a custom pins in a MapView in my iPhone app. Here is the code:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id  <MKAnnotation>)annotation
 {
     static NSString *AnnotationViewID = @"annotationViewID";

     MKAnnotationView *annotationView = (MKAnnotationView *)[myMapView  dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];

     if (annotationView == nil)
     {
         annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
     }

    if ([[annotation title] isEqualToString:NSLocalizedString(@"Current Location",@"")])  {

        MKPinAnnotationView *pin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
        //pin.pinColor = MKPinAnnotationColorRed;
        annotationView = pin;
    }
    else
    {
        NSString *pin = [NSString stringWithFormat:@"pin%i.png",[[annotation imgNumber] intValue]];
        annotationView.image = [UIImage imageNamed:pin];//Canviar la chincheta per numero
        UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
        [annotationView setRightCalloutAccessoryView:button];
        annotationView.annotation = annotation;
        annotationView.canShowCallout = YES;

    /********* Imagen a la izquierda en la burbuja *********/
    annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; 
    // Set up the Left callout
    UIButton *myDetailButton =开发者_JS百科 [UIButton buttonWithType:UIButtonTypeCustom];
    myDetailButton.frame = CGRectMake(0, 0, 23, 23);
    myDetailButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    myDetailButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

    // Set the image for the button
    //[myDetailButton setImage:[UIImage imageNamed:@"botocorreu.png"] forState:UIControlStateNormal];
    NSString *detailButton = [NSString stringWithFormat:@"%i",[[annotation imgNumber] intValue]];
    [myDetailButton setImage:[UIImage imageNamed:detailButton] forState:UIControlStateNormal];  
    // Set the button as the callout view
    annotationView.leftCalloutAccessoryView = myDetailButton;
    annotationView.canShowCallout = YES;
    }
     return annotationView;
  }

This works good but show me the users location with a red pin. I check the "show user location" in the IB. i would like to use the default blue point which will move it automatically when the user is moving, isn't correct? How can i do that?

Thanks a lot.

Add this to the top of the viewForAnnotation method:

if ([annotation isKindOfClass:[MKUserLocation class]])
    return nil;

The special user location annotation is of type MKUserLocation and returning nil in that case tells the map view to draw the default view for it which is the blue dot.

You can also remove these lines since they will no longer be needed:

if ([[annotation title] isEqualToString:NSLocalizedString(@"Current Location",@"")])  {
    MKPinAnnotationView *pin = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
    //pin.pinColor = MKPinAnnotationColorRed;
    annotationView = pin;
}
else
