To add a AGSFeature in AGSFeatureLayer

MuruganandhamKuppan1

'AGSFeatureLayer' is loaded using a url from the arcgis server. Now, i would like to add a 'AGSFeature' in 'AGSFeatureLayer'. Is it possible to add a 'AGSFeature' in a 'AGSFeatureLayer' locally or, whether i need to use 'AGSGraphicOverlay' to accomplish that. 

Kindly advice. Also give some example.

#2 Is the following way is right one to create AGSGraphic from a AGSFeature?

    AGSSymbol * symbol = [self.graphic.featureTable.featureLayer.renderer symbolForFeature:self.feature];

    AGSGraphic * graphicObj = [[AGSGraphic alloc] initWithGeometry:self.feature.geometry symbol:symbol  attributes:self.feature.attributes];

 

#3 and i tried the following way to add a feature in feature table, but nothing happens

[layr.featureTable addFeature:data completion:^(NSError * _Nullable error) {

        if(error)

        {

            nlog(@error: %@",error.localizedFailureReason);

        }   

    }];

Hi,

You don't need to use an AGSGraphic to create a new feature.

The pattern is:

1. Create a new feature on the AGSFeatureTable with geometry and attributes using AGSFeatureTable.createFeature().
2. Add the feature to the AGSFeatureTable using AGSFeatureTable.add().

See Edit features—ArcGIS Runtime SDK for iOS | ArcGIS for Developers.

Since you are working with a server (and not local data), then there is one more call to make to push your add to the server, namely applyEdits. The applyEditsWithCompletion() function is found on AGSServiceFeatureTable (and since you created your feature layer with a URL to a service, the AGSFeatureLayer.featureTable property will be an AGSServiceFeatureTable). See the Edit features (connected) sample, in particular the applyEdits call.

This should get you going.
