Feature service layer default visibility not transferred to the layers on Map

ShiminCai

Hi there,

We are on ArcGIS Runtime SDK for iOS 100.10. We set the default layer visibility to false for some of the layers in our feature services by unticking the layers in the TOC of publishing map documents. We can confirm that the default layer visibilities of those layers are false in service directory. But when we add the service layers or downloaded offline database layers to map those layer's isVisibles have become true and the layers are drawn on the map. Basically we don't want the map to draw those layers we untick in the publishing document. However, it works fine with SDK 10.2.5 for the same feature service.

Does anybody have any idea please?

Thanks,

Shimin

@ShiminCai It turns out that the defaultVisibility of the service is ignored when creating the layer from a service URL or AGSServiceFeatureTable. This is by design and behaves the same way the AGOL MapViewer does.  The reasoning behind the design is that it would be odd and potentially confusing if you added a map layer and it didn't immediately draw.  However, I understand that your use case is different.

The SDK does capture the service info correctly in the AGSServiceFeatureTable.layerInfo.isVisibleByDefault property, so a solution would be to set the initial visibility of the freshly created layer to that value.  Note that the AGSServiceFeatureTable needs to be loaded before accessing the layerInfo property.

Hope that helps.  If you have more questions, please let me know.
