add Marker on the Map using Mappy SDK IOS - ios

Question

i'm developing and iphone app and i'm working with Mappy SDK IOS.
i arrived to display the map and show my current location. but i have a problem with adding some markers on my map.
i have an NSArray that contains some objects with longitude and latitude properties.
my code to display the markers is :
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
//initialisation mot de passe + user
[MPInit initialisation:MAPPY_API_KEY];
[RMMapView class];
//show user location
self.mapView.showsUserLocation = NO;
self.mapView.showPoi = YES;
//set delegate
self.mapView.delegate = self;
MPMarkerManager *markerManager = [self.mapView markerManager];
MPMarkerCategory * category = [markerManager getCategory:#"storeLocations"];
//remove old elements
[category.dataSource removeAllElements];
//add markers on map
for(int i=0; i<self.arrayStores.count; i++) {
NSLog(#"add store %d on the map", i);
NSDictionary* currentStore = [self.arrayStores objectAtIndex:i];
float latitude = [[currentStore objectForKey:#"latitude"] floatValue];
float longitude = [[currentStore objectForKey:#"longitude"] floatValue];
CLLocationCoordinate2D locationStore = CLLocationCoordinate2DMake(latitude, longitude);
//create a new POI object with location
MPPoi * poi = [[MPPoi alloc] initWithUId:[currentStore objectForKey:#"title"] withLocation:locationStore];
[category.dataSource addElement:poi];
self.mapView.centerCoordinate = locationStore;
[poi release];
}
//category settings
category.markerColor = [UIColor greenColor];
//[category setOptimalZoom:YES];//set the zoom to be optimal : show all poi in the category
[category setHideLabelOnTheFirstShow:NO];
[category setAnimateAtFirstShow:YES];
}
and here is the log displayed on the console:
2012-06-14 17:01:18.359 Koutoubia[609:607] MappyKit version:1.40
2012-06-14 17:01:18.672 Koutoubia[609:607] add store 0 on the map
i'm i doing something wrong ?? because markers aren't displayed
the doc for adding markers on the documentation is :
//add a marker on map
MPMarkerManager *markerManager = [viewController.mapView markerManager];
MPMarkerCategory * category = [markerManager getCategory:HMP_LOC_CATEGORY];
//remove old elements
[category.dataSource removeAllElements];
//create a new POI object with location
MPPoi * poi = [[MPPoi alloc] initWithUId:locationData.address withLocation:findLocation];
[category.dataSource addElement:poi];
[poi release];
the link of the documentation is here
any ideas ?? thanks in advance

I've founded the solution ,
the problem is that i've forgot to initialize the MPMarkerCategory and add it to the markerManager on the viewDidLoad method :
//Marker initialization
MPMarkerManager *markerManager = [self.mapView markerManager];
//add a new category with green default color
[markerManager addCategory:STORE_LOC_CATEGORY withColor:[UIColor greenColor]];
