LayerDefinitions

ChrisMahlke

This question is concerning layer definitions.

I follow the sample code snippets posted at the very bottom of this page:

http://help.arcgis.com/en/arcgismobile/10.0/apis/iOS/1.8/concepts/index.html#//00pw0000004m000000.htm

Here is my code:

AGSDynamicMapServiceLayer *dyn = [[AGSDynamicMapServiceLayer alloc] initWithURL:[NSURL URLWithString:@"http://server.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_1990-2000_Population_Change/MapServer"]];
 
int layerID = 3; 
NSString *defString = @NAME = 'Middlesex County';
AGSLayerDefinition *layerDef = [AGSLayerDefinition layerDefinitionWithLayerId:layerID definition:defString];
dyn.layerDefinitions = [NSArray arrayWithObject:layerDef];
 
[mapView removeMapLayerWithName:@previous layer];
self.fbMapServiceUIView = [mapView addMapLayer:_dyn withName:@some name];

Instead of just 4 counties being loaded, the entire choropleth map is being loaded as though there were no layer definitions being applied.

Has anyone out there successfully applied layer definitions?  Any suggestions?

Thanks...

Chris,

The layer you are using is a Tiled layer not a Dynamic layer. Hence, it's not being honored.
