How does one execute an Identify task on an instance of AGSArcGISMapImageLayer? I've got a number of feature layers already on the map and running identifyLayersAtScreenPoint:tolerance:returnPopupsOnly:maximumResultsPerLayer:completion:() works as expected, but returns no results for the AGSArcGISMapImageLayer. In fact, the AGSArcGISMapImageLayer shows isPopupEnabled = false. The layer source is Tapestry Segmentation layer from: http://beitzanddaighgeo.maps.arcgis.com/home/item.html?id=eda0f20edc8448adaa3373cce237a57f and the layer is rendered correctly on the map.
Likely I'm missing something here, but how does one setup an AGSArcGISMapImageLayer so that it may be identified?
