I want to add custom annotationView callout which contains 1. Title 2. subtitles 3. a button
The button can display on the right (rightCalloutAccessoryView) or left leftCalloutAccessoryViewsides of the callout. I want to add the button in the middle of the callout and under title->subtitle. How can I do?

There is no API for this. You could try not using the standard callout (canShowCallout = NO), catch the taps and drags on the AnnotationView manually and show your own UI by adding custom Views based on the position of the AnnotationView. This seems very fragile, though.
