AGSFeatureSet as parameter for AGSGeoprocessor

Question

Hi everyone,

I'm trying to pass a AGSFeatureSet with a single point to an AGSGeoprocessor which takes as input a GPFeatureRecordSetLayer parameter:
NSMutableArray *features = [NSMutableArray array];
[features addObject:currentPoint];

AGSFeatureSet *fset = [[AGSFeatureSet alloc] init];
fset.features = features;

NSDictionary *params = [NSDictionary  dictionaryWithObjectsAndKeys:
       @Input_Facilities,fset,
       nil];

but I receive the following error when I fill the Dictionary with the fset variable.
'*** -[AGSFeatureSet copyWithZone:]: unrecognized selector sent to instance 0x4e47270'

which means that the AGSFeatureSet doesn't support the NSCopying protocol.

What I missing o mistaking?

Thanks in advance for you help.

Marco

Parameters is an array:

AGSGPParameterValue *parcel = [AGSGPParameterValue parameterWithName:@Parcel_ID type:AGSGPParameterTypeString value:@1N1E34CC  -06600];

AGSGPParameterValue *distance = [AGSGPParameterValue parameterWithName:@SearchDistance_ft type:AGSGPParameterTypeLong value:[NSNumber numberWithInt:100]];

NSArray *params = [NSArray arrayWithObjects:parcel,distance,nil];

Please have a look

If possible, can you please attach your sample application?

i think you have not set the delegate that's why you are not getting the event callbacks, put the below line in yur code before the query
 agp.delegate = self ;

I did it 😞
These are the lines before the code i've posted yesterday.
AGSGeoprocessor *agp = [[AGSGeoprocessor alloc] initWithURL:[NSURL URLWithString:kAsyncGPService]];
 agp.delegate = self;
 agp.interval = 5;

I think that the problem are the parameters in the Dictionary. But I don't know why. They are all GPString except the GPFeatureSetLayer for the point.
