I can't show web map using AGSWebMap

- (void) webMapDidLoad:(AGSWebMap*) webMap {
    //webmap data was retrieved successfully
    NSLog(@"load successfully");
    [self.webmap openIntoMapView:self.mapView];
    [self.mapView setNeedsDisplay];
}

    //webmap data was not retrieved
    //alert the user
    NSLog(@"Error while loading webmap: %@",[error localizedDescription]);
}

-(void)didOpenWebMap:(AGSWebMap*)webMap intoMapView:(AGSMapView*)mapView{
    //web map finished opening
    NSLog(@"delegate method: didOpenWebMap:(AGSWebMap*)webMap intoMapView:(AGSMapView*)mapView");
}

-(void)didLoadLayer:(AGSLayer*)layer{
    //layer in web map loaded properly

I have retained webMap

@property (retain, nonatomic) IBOutlet AGSMapView *mapView;
@property (retain, nonatomic) AGSWebMap *webmap;

Nobody can help ?

Did you make the connection between the property and Interface Builder object?

Hi,

I think the problem is that your WebMap has as its basemap layer a Bing Maps layer, for which you need to specify your Bing Maps key.

If you add this delegate method, and return your key, you should be good to go:

-(NSString*)bingAppId{
    return @"YOUR BING MAPS KEY";
}

This page tells you how to go about getting a key. See also the sample delegate in the Concepts document.

Hope this helps. Let us know how you get on.

Cheers,

Nick.
