Display pin on location by Lat,Lon coordinates dynamically

Vadimv — Wed, 10 Oct 2012 04:51:51 GMT

I want to display an pin image, to display it with my current gps coordinates its eady...just use start.
How can i set this pin to a specific coordinates of Lat,Lon...

I tried the next thing but its doest show nothing

AGSPictureMarkerSymbol *myMarkerSymbol = [AGSPictureMarkerSymbol pictureMarkerSymbolWithImageNamed:@"Pushpin.png"];
        myMarkerSymbol.color = [UIColor redColor];

[AGSPoint pointWithX:32.0636
                       y:34.7922
  spatialReference:[AGSSpatialReference spatialReferenceWithWKID:43276]];

  AGSGraphic* myGraphic =
 [AGSGraphic graphicWithGeometry:myMarkerPoint
                             symbol:myMarkerSymbol
                         attributes:nil
               infoTemplateDelegate:nil];
    
    [myGraphic addGraphic:myGraphic];
   [self.myGraphicsLayer dataChanged];

   [self.mapView addMapLayer:self.myGraphicsLayer withName:@"test];

Any ideas?

1. You are creating point with spatial reference 43276. Is that correct? Or you meant 4326?

[AGSPoint pointWithX:32.0636 y:34.7922 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:43276]];

2. Is you point's spatial reference is same as map's spatial reference (self.mapView.spatialReference)?

3. You should add graphic to graphics layer, not graphic to graphic.

//[myGraphic addGraphic:myGraphic];
[self.myGraphicsLayer addGraphic:myGraphic];

Hope this helps!

Thanks' Nimesh

[HTML]1. You are creating point with spatial reference 43276. Is that correct? Or you meant 4326?

[AGSPoint pointWithX:32.0636 y:34.7922 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:43276]];

Yeah i meant 4326(sorry for that),and tried with 4326. i just was trying some stuff and saved it like that.

[HTML]2. Is you point's spatial reference is same as map's spatial reference (self.mapView.spatialReference)?[/HTML]

Yes,Its the same..i'm using the same point to zoom the map,so the point is ok.

3. You should add graphic to graphics layer, not graphic to graphic.

[HTML]//[myGraphic addGraphic:myGraphic];
[self.myGraphicsLayer addGraphic:myGraphic];[/HTML]

I tried that too,its not changing. i'm using some layers to display stuff on the map.so the

myGraphicsLayer

is a layer that on the moment of calling this code is showen on the map, i tried also setting it to layer that not displayed and then calling it...

nothing works..

Could you please try adding your graphics layer first to the map? and then try to add the graphic?

//add graphics layer first the map
[self.mapView addMapLayer:self.myGraphicsLayer withName:@"test];

//then add graphic to graphics layer
AGSPictureMarkerSymbol *myMarkerSymbol = [AGSPictureMarkerSymbol pictureMarkerSymbolWithImageNamed:@"Pushpin.png"];
        myMarkerSymbol.color = [UIColor redColor];
[AGSPoint pointWithX:32.0636 y:34.7922 spatialReference:[AGSSpatialReference spatialReferenceWithWKID:4326]];
AGSGraphic* myGraphic = [AGSGraphic graphicWithGeometry:myMarkerPoint symbol:myMarkerSymbol attributes:nil infoTemplateDelegate:nil];
[self.myGraphicsLayeraddGraphic:myGraphic];
[self.myGraphicsLayer dataChanged];
