1. Create a UIView subclass for the pin callout view.
2. Create a subclass of MKAnnotationView for your map pins.
3. Add an instance of the callout view subclass to your MKAnnotationView subclass.
4. Add a property to toggle the callout view to your MKAnnotationView subclass. This example fades in/out:

   - (void)setShowCustomCallout:(BOOL)showCustomCallout
   {
       [self setShowCustomCallout:showCustomCallout animated:NO];
   }
