Question

我正在开发和iphone应用程序，我正在使用Mappy SDK IOS。

我到了显示地图并显示我当前的位置。但我在地图上添加一些标记时遇到问题。

我有一个NSArray，其中包含一些具有经度和纬度属性的对象。我显示标记的代码是：

    - (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];

}

以下是控制台上显示的日志：

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

我正在做错事吗？因为没有显示标记

在文档上添加标记的文档是：

//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];

任何想法？提前谢谢

我已经创建了解决方案，问题是我忘了初始化MPMarkerCategory并将其添加到markerManager方法的viewDidLoad：

//Marker initialization
    MPMarkerManager *markerManager = [self.mapView markerManager];
    //add a new category with green default color
    [markerManager addCategory:STORE_LOC_CATEGORY withColor:[UIColor greenColor]];
