问题
HI,
I have a Mapview with some marker points + a marker for current location.
Now, what I want to do here is, when user drag or traverse through mapview, I want to find coordinate (latitude, longitude) of the new center location after map has been dragged.
I want to clarify once again, I am not talking about dragging the marker/point, I am talking about dragging the map with touch.
Thanks in advance.

Look for theMapView.region.center or theMapView.centerCoordinate (should be the same) in your MapView's delegate -mapView:regionDidChangeAnimated: method.

Judging by this document:
http://developer.apple.com/iphone/library/DOCUMENTATION/MapKit/Reference/MKMapView_Class/MKMapView/MKMapView.html
You can get that with the centerPosition property of your MKMapView. To tell when the location changes, implement the -mapView:regionDidChangeAnimated: method in your MKMapViewDelegate.
