Now that I have loaded a map in my app, I need to show a marker annotation for a location. Here is the code I'm using but nothing is showing on the map:
CLLocation *location = [[CLLocation alloc] initWithLatitude:douLat longitude:douLon];
AGSPoint *markerPoint = [AGSPoint pointWithLocation:location];
AGSGraphicsLayer* myGraphicsLayer = [AGSGraphicsLayer graphicsLayer];
[self.ibMapView addMapLayer:myGraphicsLayer withName:@"Graphic Layer"];
AGSPictureMarkerSymbol *markerSymbol = [AGSPictureMarkerSymbol pictureMarkerSymbolWithImageNamed:@"existing_project_icon.png"];
AGSGraphic* myGraphic = [AGSGraphic graphicWithGeometry:markerPoint
symbol:markerSymbol
attributes:nil];
// Add the graphic to the Graphics layer
[myGraphicsLayer addGraphic:myGraphic];
[self.ibMapView.callout showCalloutAtPoint:markerPoint forFeature:myGraphic layer:myGraphicsLayer animated:YES];
Please help.
