Problems to Add Features in AGSFeatureLayerEditingDelegate

ViniciusMachuca — Thu, 30 Aug 2012 11:53:17 GMT

I need add geometry to Feature Service, but not working. 😞

My flow is:

1. Adopt AGSFeatureLayerEditingDelegate delegate.

2. AGSFeatureLayer *featureLayer = [AGSFeatureLayer featureServiceLayerWithURL: urlFeatureLayer mode: AGSFeatureLayerModeOnDemand];

3. featureLayer.editingDelegate = self;

4.     NSMutableDictionary *graphicAttributes = [[NSMutableDictionary alloc] init];
[graphicAttributes setObject:@"EXAMPLE1" forKey:@"FIELD1"];
[graphicAttributes setObject:@"EXAMPLE2" forKey:@"FIELD2"];

5. AGSGraphic *graphic = [AGSGraphic graphicWithGeometry:selectedMaPoint symbol:nil attributes:graphicAttributes infoTemplateDelegate:self];

6. [featureLayer addFeatures:[NSArray arrayWithObject:graphic]];

The strange thing is that no delegate is called!

Ex:

- (void)featureLayer:(AGSFeatureLayer *)featureLayer operation:(NSOperation*)op didFeatureEditsWithResults:(AGSFeatureLayerEditResults *)editResults;

- (void)featureLayer:(AGSFeatureLayer *)featureLayer operation:(NSOperation*)op didFailFeatureEditsWithError:(NSError *)error;

Thanks!

Create retain property for feature layer and then try.

//in .h file
@property (nonatomic, retain) AGSFeatureLayer *featureLayer;

//in .m file
self.featureLayer = [AGSFeatureLayer featureServiceLayerWithURL: urlFeatureLayer mode: AGSFeatureLayerModeOnDemand];
self.featureLayer.editingDelegate = self;

I am also trying to do the exact same steps to add feature to a feature layer. The error I am seeing in the log is

AGSJSONRepresentation failed: Error is: NaN is not a valid number in JSON

Do you have a valid geometry in JSON?

Hi Nimesh,

I have created property for feature layer and I'm trying to add feature from query result. But unable to do that.....delegate methods are not getting called. Below is my code. Will you please help me with this.

- (void)queryTask:(AGSQueryTask *)queryTask operation:(NSOperation*)op didExecuteWithFeatureSetResult:(AGSFeatureSet *)featureSet

{

NSInteger index;

for (index = 0; index <featureSet.features.count; index++)

{

AGSSimpleFillSymbol * fillSym = [AGSSimpleFillSymbol simpleFillSymbol];

fillSym.style = AGSSimpleFillSymbolStyleSolid;

fillSym.color = [UIColor orangeColor];

AGSGraphic * graphic = [featureSet.features objectAtIndex: index];

graphic.symbol = fillSym;

[self.featureLayer1 addFeatures:@[graphic]];

}

[self.featureLayer1 refresh];

}
