map zoomed notification

I am trying to get a notification message for when the map has zoomed, to then fire off another method to do something. I read in the API docs that there is a notification sent out from AGSMapView for "MapDidEndZooming":

"The map component broadcasts four notifications - MapViewDidLoad, MapTimeExtentChanged, MapDidEndPanning and MapDidEndZooming. Observers interested in these notifications can register for them using the default NSNotificationCenter."

I have tried this in my viewController implementation:

self.mapView.layerDelegate = self;
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didReceiveZoomMessage: ) name:MapDidEndZooming object:nil];

but I keep getting error stating the "MapDidEndZooming" is undeclared.

Use @"MapDidEndZooming" as the name argument. It needs to be a string.

Thanks Divesh! That worked.

Just curious - Why are these 4 notifications not implemented in a protocol?
