AGSBingMapLayer Class Reference

---

Description

An instance of this class allows you display maps from Bing Maps.

In a Model-View-Controller architecture, this object represents the Model. The corresponding View object, AGSTiledLayerView, is created when this layer is added to an instance of AGSMapView.

Defined in:

AGSBingMapLayer.h ( ArcGIS library)

Since:

1.0

Member Function Documentation

- ((deprecated) __attribute__

AGSBingMapLayer maintains a local cache on the device containing tiles retrieved from the map service. This makes redrawing the map much faster and also reduces overall network usage. This method can be used to clear the local cache.

Returns:

Returns NO if no tiles removed from cache.

Since:

1.0

Deprecated:

Use [AGSTileRequestOperation clearAGSTiles] instead.

- (void) dataChanged

This method tells the layer that the data has changed and it should be redrawn.

Since:

1.0

Implemented in AGSGraphicsLayer.

- (id) initWithAppID:		(NSString *)	appID
style:		(AGSBingMapLayerStyle)	style

Initialize this layer with an AppID and a map style.

Parameters:

	appID	The appID authorized to use Bing Maps.
	style	The style of the map. See style.

Returns:

A new Bing Maps layer object.

Since:

1.0

- (void) layerDidFailToLoad:

(NSError *)

error

Method to notify the delegate that a layer failed to load. This method will also post a "LayerFailedToLoad" notification that can be observed by the developer.

Parameters:

error

Information regarding the cause of the layer failing to load.

Since:

1.0

- (void) layerDidLoad

Method to notify the delegate that a layer successfully loaded. This method will also post a "LayerDidLoad" notification that can be observed by the developer.

Since:

1.0

- (NSOperation<AGSTileOperation>*) retrieveImageAsyncForTile:

(AGSTile *)

tile

Retrieve tile asynchronously. This method must be implemented by subclasses.

Parameters:

tile

The tile to get image for.

Returns:

NSOperation that implements the protocol AGSTileOperation for current tile request.

Since:

1.0

Implements AGSLayer.

- (AGSEnvelope*) initialEnvelope [read, retain]

Initial extent of Bing Maps.

Since:

1.0

Implements AGSLayer.

- (BOOL) loaded [read, assign, inherited]

A property indicating whether the layer is loaded and ready to be used. When the layer is loaded, the value becomes YES, and layer properties can be accessed.
