AGSTiledLayerView Class Reference
Description
In a Model-View-Controller architecture, this object represents the View. When corresponding Model objects, subclasses of AGSTiledLayer, are added to the map, this view object is used internally to display maps from the cached map service.
This class extends UIView and implements the AGSLayerView protocol and the AGSTiledLayerTileDelegate protocol. You can change the transparency of the layer by modifying the alpha property.
- Defined in:
- AGSTiledLayerView.h ( ArcGIS library)
- Since:
- 1.0

- AGSTiledMapServiceLayer

- Parameters:
-
layer The layer that was loaded.
- Since:
- 1.0
| - (AGSEnvelope*) mapFullEnvelope | [required, inherited] |
The layer can call this function on its delegate to find out what the full envelope of the map is.
- Since:
- 1.0
| - (void) mapIsPanning: | (AGSLayerViewRequestParams *) | params |
Delegate method that is fired when the map starts to pan.
- Parameters:

params The parameters of the layer view's current request.
- Since:
- 1.0
| - (void) mapPanned: | (AGSLayerViewRequestParams *) | params |
Delegate method that is fired when the map has finished panning.
- Parameters:
-
params The parameters of the layer view's current request.
- Since:
- 1.0
| - (void) mapTimeExtentChanged: | (AGSLayerViewRequestParams *) | params |
Delegate method that is fired when the map's time extent has been changed.
- Parameters:
-
params The parameters of the layer view's current request.
- Since:
- 1.0
| - (void) mapZoomed: | (AGSLayerViewRequestParams *) | params |
Delegate method that is fired when the map has finished zooming.
- Parameters:
-
params The parameters of the layer view's current request.
- Since:
- 1.0
| - (void) tiledLayer: | (AGSTiledLayer *) | layer | ||
| operationDidFailToGetTile: | (NSOperation< AGSTileOperation > *) | op | ||
[optional, inherited] |
Tells the delegate a tile was not retrieved.
- Parameters:

Property Documentation
- (AGSLayer*) agsLayer [read, write, retain, inherited] |
Layer being represented.
- Since:
- 1.0
- (BOOL) drawDuringPanning [read, write, assign] |
Flag to determine whether or not the layer should draw while the map is panning.
- Since:
- 1.0
Reimplemented from <AGSLayerView>.
- (BOOL) drawDuringZooming [read, write, assign] |
Flag to determine whether or not the layer should draw while the map is zooming.
- Since:
- 1.0
Reimplemented from <AGSLayerView>.
- (BOOL) enableTileAnimation [read, write, assign] |
Flag to determine whether or not tile animations should be enabled. If enabled, tiles will appear to fade in when they are retrieved.
- Since:
- 1.0
- (NSError*) error [read, retain, inherited] |
Latest error, if any. May be error returned by service or client.
- Since:
- 1.0
- (BOOL) limitMemoryUsage [read, write, assign] |
Flag to limit memory usage. This should be used when targeting older devices such the original iPhone or iPhone 3G.
- Since:
- 1.0
- (AGSMapView*) mapView [read, write, assign, inherited] |
Map view this layer view is contained in.
- Since:
- 1.0
- (double) maxResolution [read, assign] |
This is the maximum AGSMapView resolution (map units per point) that this layer renders at. This is a calculation determined by the tile-info's resolution of the first LOD, the layer's renderNativeResolution property and the scale of the screen.
- Since:
- 2.1
- (double) minResolution [read, assign] |
This is the minimum AGSMapView resolution (map units per point) that this layer renders at. This is a calculation determined by the tile-info's resolution of the last LOD, the layer's renderNativeResolution property and the scale of the screen.
- Since:
- 2.1
- (NSString*) name [read, write, copy, inherited] |
Name of the view.
- Since:
- 1.0
