Adding marker on a map

MukulSonwalkar — Sun, 12 Dec 2021 16:52:33 GMT

Hello,

I am trying to add a marker on my map but i am getting some warning (code highlighted) and application crashes on build

Here is code

id<AGSLayerView> graphicsLayerView = [self.mapView.mapLayerViews objectForKey:@"GraphicsLayer"];
 AGSGraphicsLayer* myGraphicsLayer = (AGSGraphicsLayer*)graphicsLayerView.agsLayer;
 //create a marker symbol to be used by our Graphic
 AGSSimpleMarkerSymbol *myMarkerSymbol =
 [AGSSimpleMarkerSymbol simpleMarkerSymbol];
 myMarkerSymbol.color = [UIColor blueColor];
 
 //Create an AGSPoint (which inherits from AGSGeometry) that
 //defines where the Graphic will be drawn
 AGSPoint* myMarkerPoint =
 [AGSPoint pointWithX:-93.2984
        y:44.9409
  spatialReference:self.mapView.spatialReference];
 
 //Create the Graphic, using the symbol and
 //geometry created earlier
 AGSGraphic* myGraphic = [AGSGraphic graphicWithGeometry:myMarkerPoint symbol:myMarkerSymbol attributes:nil infoTemplate:nil];
 
 //Add the graphic to the Graphics layer
 [myGraphicsLayer addGraphic:myGraphic];
 
 //Tell the layer to redraw itself
 [myGraphicsLayer dataChanged];

The warning: AGSGraphics may not respond to '+graphicWithGeometry:symbol:attributes:infoTemplate

Am i missing something??? Do i have to include any file/framework??

Thanks

If you are using the final version of ArcGIS API for iOS 1.0, you will need to replace infoTemplate with infoTemplateDelegate

AGSGraphic* myGraphic = [AGSGraphic graphicWithGeometry:myMarkerPoint symbol:myMarkerSymbol attributes:nil infoTemplateDelegate:nil];

Thank you for your reply. I did try with the infoTemplateDelegate and i don't get the warning but i don't see the blue pin on the map. I am using the same code from last post.

Any ideas??
Thanks

Have you initialized the Graphics Layer and add it to the map before you execute those statements?
You will need to execute the following first:

AGSGraphicsLayer* graphicsLayer = [AGSGraphicsLayer graphicsLayer];
[self.mapView addMapLayer:graphicsLayer withName:@"GraphicsLayer"];

The name should match what your codes attempt to retrieve.
