Hi All,

I'm working on project which is related to ARCGIS server on iPad. So in my application I'm trying to load 3 feature layers on basemap. I'm able to do that. But problem is like not overtime it get loaded and second thing is how can I get more information about feature layer which has data in it.

Below is the code which I used to show layers on map.

 

 

    // Add basemap.

    NSURL* url = [NSURL URLWithString: @"http://services.arcgisonline.com/arcgis/rest/services/World_Topo_map/mapserver"];

    AGSTiledMapServiceLayer* layer = [AGSTiledMapServiceLayer tiledMapServiceLayerWithURL: url];

    layer.delegate = self;

    [self.mapView addMapLayer:layer withName:@"Streets"];

 

    //zoom to an area

    AGSEnvelope *envelope = [AGSEnvelope envelopeWithXmin:-1.34732920649E7 ymin:4533851.309500001 xmax:-1.3431785844E7

  ymax:4641521.468800001  spatialReference:self.mapView.spatialReference];

    [self.mapView zoomToEnvelope:envelope animated:NO];

   

    // Structures.

    NSString *urlString = [self.currentWorkOrder.detectionURL substringToIndex:[self.currentWorkOrder.detectionURL length]-1];

 

    self.featureLayerURL0 = [NSURL URLWithString:[NSString stringWithFormat:@"%@0",urlString]];

   

    self.featureLayer0 = [AGSFeatureLayer featureServiceLayerWithURL:self.featureLayerURL0 mode:AGSFeatureLayerModeOnDemand];

    self.featureLayer0.delegate = self;

    [self.mapView addMapLayer:self.featureLayer0 withName:@"CloudData0"];

   

    // Alignment.

    self.featureLayerURL = [NSURL URLWithString:[NSString stringWithFormat:@"%@1",urlString]];

   

    self.featureLayer = [AGSFeatureLayer featureServiceLayerWithURL:self.featureLayerURL mode:AGSFeatureLayerModeOnDemand];

    self.featureLayer.delegate = self;

    [self.mapView addMapLayer:self.featureLayer withName:@"CloudData"];

   

    // Detections.

    self.featureLayerURL1 = [NSURL URLWithString:[NSString stringWithFormat:@"%@2",urlString]];

   

    self.featureLayer1 = [AGSFeatureLayer featureServiceLayerWithURL:self.featureLayerURL1 mode:AGSFeatureLayerModeOnDemand];

    self.featureLayer1.delegate = self;

    PO(self.featureLayer1.fields);

    [self.mapView addMapLayer:self.featureLayer1 withName:@"CloudData1"];

 

If anyone has any idea. Please help me out.

 

 

Thanks in advance.
