Make the newAnnotation a MKAnnotationView rather than a MKPinAnnotationView.

newAnnotation.canShowCallout = YES; will do it. Or is it something else that you want – visakh7 Mar 22 '11 at 09:44

in which delegate method i should find the closest annotation to current location – Manish Jain Mar 22 '11 at 09:47
you can make use of [location getDistanceFrom:currentLocation]; to get distance between the coordinates which can help you to find the closest one. – visakh7 Mar 22 '11 at 09:51
