how to detect change of zoom or location on mapview
Dear Expert:
I'm createing an iPhone application which shows restaurants from our database. Now we are adding all annotations of restaurants on map. To improve performance, we want to add all the marks that fits inside the map, however, we need to call the function that fills this marks every time that user changes the zoom level on the map or every time user moves the map.
How can we detect when user changes the view of the map ?
Thank you.
