[LEFT]Hello Everyone,
I am having trouble changing my base map from and to one of the ESRI basemaps in my app. I can get the portal group and items fine but when I try to get a AGSWebMap from the PortalItem and then try to create a base map from there I get a null basemap value. I have been trying to follow this thread [/LEFT]http://forums.arcgis.com/threads/57085-basemap-gallery?highlight=base and the portal sample but i seem to be failing somewhere. Below is my current code for trying get the AGSWebMapBaseMap so I can use the openIntoMapView withAlternateBaseMap method.
Any help would be great.
Cheers,
Jeff

(void) didSelectNewBaseMap:(AGSPortalItem *)BaseMapPortalItem { AGSWebMap *NewBaseWebMap = [[AGSWebMap alloc] initWithPortalItem:BaseMapPortalItem]; AGSWebMapBaseMap *NewWebmapBaseMap = [[AGSWebMapBaseMap alloc]init]; NewWebmapBaseMap = [NewBaseWebMap baseMap]; [self.webmap openIntoMapView:self.mapView withAlternateBaseMap:NewWebmapBaseMap resetMapView:NO]; } 
Your code should look like this...
-(void) didSelectNewBaseMap:(AGSPortalItem *)BaseMapPortalItem { AGSWebMap *NewBaseWebMap = [AGSWebMap webMapWithPortalItem:BaseMapPortalItem]; NewBaseWebMap.delegate = self; } //webmap delegate - (void)webMapDidLoad:(AGSWebMap *)webMap { [self.webmap openIntoMapView:self.mapView withAlternateBaseMap:webMap.baseMap]; }Regards,
