I've been experimenting with the My First iOS app example, trying to get it to display a Bing map layer I created on ArcGIS.com. However, the layer doesn't display. In the sample app's code, when it says:
NSURL *mapUrl = [NSURL URLWithString:@"http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"];
AGSTiledMapServiceLayer *tiledLyr = [AGSTiledMapServiceLayer tiledMapServiceLayerWithURL:mapUrl];
[self.mapView addMapLayer:tiledLyr withName:@"Tiled Layer"];
what am I supposed to replace the mapUrl from? The bit.ly link created through the share function on ArcGIS.com doesn't work, since it links directly to a map viewer displaying the map. I'd like to get the map directly to put into my sample iOS app.
