Unable to show feature layer through IOS arcgis runtime sdk

DasNobel — Fri, 17 Mar 2017 12:26:07 GMT

Hi,

I am using below code to show feature layer but it is not showing in ios app. I have created this feature layer through arcgis online.

//initialize map with basemap
let map = AGSMap(basemap: AGSBasemap.streetsBasemap())

//assign map to the map view
self.mapView.map = map



//initialize service feature table using url
let featureTable = AGSServiceFeatureTable(URL: NSURL(string: "https://services7.arcgis.com/JRY73mi2cJ1KeR7T/arcgis/rest/services/NewYorkHospitalLayer/FeatureServer")!)
//create a feature layer
let featureLayer = AGSFeatureLayer(featureTable: featureTable)

//add the feature layer to the operational layers
map.operationalLayers.addObject(featureLayer)

Thanks

Hi!

You need to specify specific layer inside featureService

let featureTable = AGSServiceFeatureTable(url: URL(string: "https://services7.arcgis.com/JRY73mi2cJ1KeR7T/arcgis/rest/services/NewYorkHospitalLayer/FeatureServer/0")!)

regards,

David

Thanks, David. Now I am able to see layer.

Is it possible to show above layer and basemap as an offline mode?

Hi Das,

You can load basemap offline mode by creating a tpk file. For more information please check this:

ArcGIS Local Tiled layer—ArcGIS Runtime SDK for iOS | ArcGIS for Developers

For the featureLayer in offline mode, you need to prepare the data for offline mode, basically enable the sync functions and then you can either choose view-only or editable offline data based on your requirement.

For more information about featureLayer offline, please check: Create an offline map—ArcGIS Runtime SDK for iOS | ArcGIS for Developers

Hope this can help.
