how can i get AGSRelatedFeatureQueryResult with all field values?

PrasadJ — Mon, 31 Dec 2018 04:09:59 GMT

Please help me to resolve the issue.

i need to display all the field values of the relation table information of a feature on related feature class,

But we are not getting full attribute information

below code snippet

self.featureTableParking.queryRelatedFeatures(for: self.selectedParking ) { [weak self] (results:[AGSRelatedFeatureQueryResult]?, error:Error?) in

if let error = error {

//display error

self?.presentAlert(error: error)

}

else {

....

}

below is the snippet for extracting the field of "totalspots" but i am getting value of displayFieldName

let result = self.results[0]

let feature = result.featureEnumerator().allObjects[indexPath.row]

let displayFieldName = result.relatedTable!.layerInfo!.displayFieldName

let fields=result.relatedTable!.fields

print(fields)

let value1 = feature.attributes.value(forKeyPath: "TOTALSPOT")

print(value1.debugDescription)

how can i get all the attribute information of all field

Hi Prasad,

What result you see for the following code? Does it print only one field or all fields?

let fields=result.relatedTable!.fields
print(fields)

Hi Prasad,

Please use queryRelatedFeaturesForFeature:parameters:queryFeatureFields:completion: method to query related feature and specify `queryFeatureFields` as `AGSQueryFeatureFieldsLoadAll`.

Hope this helps!
