Is there a way to detect that the extent has changed in an app using the ESRI iOS SDK?

Question

Is there a delegate, callback, or other method that can be used to detect that the extent of the map has been changed in the ESRI iOS SDK?

Answer 1

According to the class reference for AGSMapView, there are two NSNotifications that are broadcast whenever the map pans or zooms to a new extent. Set up a listener for those notifications.

The map component also broadcasts 2 notifications -

AGSMapViewDidEndPanningNotification and #AGSMapViewDidEndZoomingNotification .
