Selecting a graphic in AGSGraphicsOverlay

NikolayYekimov1 — Fri, 19 May 2017 21:17:53 GMT

I am trying to migrate from iOS SDK 10.2.5 to 100.0.1 and having some questions. I read migration guide and checked examples on the github and still can't get how to select a graphic.

First of all, how to specify a selectionSymbol. In 10.2.5 I used to set `AGSGraphicsLayer.selectionSymbol`, the AGSGraphicsOverlay doesn't have such property. It seems that now the layer isn't anymore responsible for graphics selection but still have a method `clearSelection()`.

So it looks like I should use `self.mapView.identify(AGSGraphicsOverlay, ...)` method on map touch and then run graphic.isSelected = true on the results. Is it a correct plan? And still how to specify a selection symbol? Or should I change the graphic.symbol each time?

Hi Nikolay Yekimov,

Based on my test, it looks like in 100.0.0, when you identify the graphic, it doesn't means you selected it.

I use this method to check:

self.graphicsOverlay.selectedGraphics()
‍‍‍

And it returns an empty array. So you have to call isSelected = true at this moment.

Here is the screenshot that illustrate the result:

Sounds good. So my assumption was correct.

And what is about specifying selection symbol? I want to use another symbol for a selected graphic, not a color but a graphic symbol. Do you have any ideas?

We don't provide the ability to specify a selection symbol. If you want to use a different symbol for selected graphics, assign the selected graphics a new symbol, and revert the symbol back when you unselect them
