Decode geometry shape

SotlarStéphane — Tue, 03 Mar 2015 12:55:37 GMT

Hello,

I have a problem to decode the shape attribute for adding the feature.geometry on a graphic layer.

Code for iOS :

-(void)resultatRecherche{

//on affiche le quartier qui est associé au nom recherche

featureForArray = [arrayQuartierRechercher objectAtIndex:0];

NSLog(@"feature rechercher : %@", featureForArray);

//NSLog(@"Geometry : %@", featureForArray.geometry.ags_JSONRepresentation);

//on essaye de redefinir les infos de shape

//NSString *shape = [featureForArray valueForKey:@"shape"];

//NSString* jsonPointAsString = @"{ \"x\" : -118.4 , \"y\" : -45.2 , \"spatialReference\" : {\"wkid\" : 4326} }";

//NSDictionary *json = [jsonPointAsString AGSJSONValue];

//AGSPoint* point = [[AGSPoint alloc] initWithJSON:json];

//AGSGeometry *testGeo = [featureForArray valueForKey:@"shape"];

//featureForArray.geometry = testGeo;

AGSSimpleFillSymbol *innerSymbol = [AGSSimpleFillSymbol simpleFillSymbol];

innerSymbol.color = [[UIColor redColor] colorWithAlphaComponent:0.80];

innerSymbol.outline = nil;

//graphicSelect = [AGSGraphic graphicWithGeometry:featureForArray.geometry symbol:innerSymbol attributes:nil];

//[myGraphicsLayer addGraphic:graphicSelect];

}

Any idea ?

From the stack trace it appears that your featureForArray is in fact an NSDictionary

That is why the app crashes when you try to access the geometry as featureForArray.geometry

You should instead get the X & Y values out of the dictionary and create an AGSPoint with those values and the appropriate spatial reference
