Objects not getting plotted on bing maps

TariqMohd — Tue, 06 Sep 2011 12:15:56 GMT

So as per your documentation that to instantiate an AGSBingMapLayer, I need to provide a valid Bing Maps Key and a style for the imagery -- Roads, Aerial, or Aerial with labels.

AGSBingMapLayer* layer = [[AGSBingMapLayer alloc] initWithAppID:Bing_Key style:AGSBingMapLayerStyleRoad];
[mMapView addMapLayer:layer withName:@"Bing_Key"];
[layer release];

where Bing_Key i am fetching from service.

So I am able to show all 3 types of bing maps but my objects are not getting plotted on bingmap while all objects are getting easily plotted using AGSTiledMapServiceLayer for Street, Satellite etc.

I'm sorry to say but I'm not able to fully understand your question. What you mean by "objects not getting plotted on bing maps"?

By providing valid AppId of bing layer, are you able to see the bing maps (all three styles) on map view?

Yes by providing valid AppId of bing layer, i am able to load bing maps.

But whenever I am trying to use below line then its crashing
[self.mapView addMapLayer:mObjectsGraphicsLayer withName:@"Objects"];

if i will not use addMapLayer then i cannot plot any image/object on map layer.

where mObjectsGraphicsLayer = [AGSGraphicsLayer graphicsLayer];

So, you are saying you are not able to add a graphics layer on top of bing layer? If yes, it should just work. Could you please provide a complete code or a sample application?

I have fixed the problem by calling addMapLayer for graphic layer in didLoadLayerForLayerView delegate.

I dont know whether it is permanent solution or not but for time being I have fixed that.

Issue was like If I add AGSBingMapLayer to the mapLayer and in next line if I add graphic layer to the map layer then application was crashing. So for providing some delay I have added graphic layer related codes in didLoadLayerForLayerView delegate.

But still sometime I get the crash if I use this line

self.objectsGraphicsLayer=[AGSGraphicsLayer graphicsLayer];
[self.mapView addMapLayer:mObjectsGraphicsLayer withName:kObjectsLayerNameKey];

here is the crash log:

You are passing the name of graphics layer as kObjectsLayerNameKey in following codeline. Is it a valid string?

[self.mapView addMapLayer:mObjectsGraphicsLayer withName:kObjectsLayerNameKey];

TariqMohd — Thu, 15 Sep 2011 04:41:09 GMT

Yes this is the right string:

#define kObjectsLayerNameKey @"layer_object_name"

It should work. Could you please attach a sample app (hide the bing app id) to test?
