Trying to get envelope information

JerryChapman — Wed, 14 Dec 2011 20:28:31 GMT

Hi,
I'm new at this, I'm trying to get envelope information from a AGSFeatureSet. My query works, it returns 1 object. I also used the returnGeometry = YES in my setup of the query. The problem I'm having is I cannot write the statement correctly to get the envelope information. My statement keeps giving me an error when I add .geometry. Here is the code:

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

    AGSEnvelope *env = [((AGSFeatureSet*)[featureSet.features objectAtIndex:0]).geometry];
    [self.mapView zoomToEnvelope:env animated:YES];

}
Any help would be appreciated,

Jerry

Your code should be...

AGSGraphic *graphic = [featureSet.features objectAtIndex:0];
AGSEnvelope *env = (AGSEnvelope *)graphic.geometry.envelope;
