- (void) mapView:		(AGSMapView *)	mapView
didLoadLayerForLayerView:		(UIView< AGSLayerView > *)	layerView
				[optional]

Tells the delegate a layer that was added to the map was loaded.

Parameters:

	mapView	Map to which layer has been added.
	layerView	Layer view that was added to map

- (void) mapView:		(AGSMapView *)	mapView
failedLoadingLayerForLayerView:		(UIView< AGSLayerView > *)	layerView
baseLayer:		(BOOL)	baseLayer
withError:		(NSError *)	error
				[optional]

Tells the delegate a layer that was added to the map could not be loaded. If the layer that failed is the base layer, the map will be in an unloaded and waiting state until the base layer is either removed, resubmitted or replaced.

	mapView	Map to which layer had to be added.
	layerView	Layer view that failed to be added.
	baseLayer	Whether or not the layer is the map's current designated base layer.
	error	Error describing reason for failure.

Parameters:

	mapView	Map to which layer had to be added.
	layerView	Layer view that failed to be added.
	error	Error describing reason for failure.

- (BOOL) mapView:		(AGSMapView *)	mapView
shouldFindGraphicsInLayer:		(AGSGraphicsLayer *)	graphicsLayer
atPoint:		(CGPoint)	screen
mapPoint:		(AGSPoint *)	mappoint
