Z-order of AGSGraphic

Question

Is it possible to change the z-order of an AGSGraphic when it is selected? The use case is when there are heaps of points on the map and the user selects one from the crowd, it's not always clear which graphic was selected. I'd like to change the image of the symbol and bring it to the front if possible.

I don't see any properties on AGSGraphicsLayer that might allow you to "select" a graphic, and neither do I see any comparable properties on AGSGraphic or AGSSymbol.

Thanks,

You need to call dataChanged method of AGSGraphicsLayer after updating symbol.

You'll have to create a new symbol and assign to graphic.

Great, that's what I thought. I've got a prototype working that grabs the graphic from the mapView:didClickAtPoint: method but the Graphic that I pull from the ASGGraphics array doesn't refresh or change when I give it a new symbol. Must I retain each AGSGraphic (and thus its symbol) in some managed data structure and update THAT instance of the AGSGraphic rather than the one returned from mapView:didClickAtPoint: ? I wonder if the graphic returned there is the same instance that I need to update.
