i want to get tile by operationDidGetTile methods in AGSTiledLayerTileDelegate, but when operationDidGetTile was called,basemap can not display on AGSMapView. the sample code is below:
        //.h file
        @interface DBViewController : UIViewController<AGSTiledLayerTileDelegate,...

        //.m file
        AGSTiledMapServiceLayer *tiledLayer = [[AGSTiledMapServiceLayer alloc] initWithURL:[NSURL URLWithString:layerUrl]];
        UIView<AGSLayerView>* lyr = [self.BaseMapView addMapLayer:tiledLayer withName:BASEMAPLAYER_NAME];
        [tiledLayer setTileDelegate:self];
        lyr.drawDuringPanning = YES;

       #pragma mark - AGSTiledLayerTileDelegate
       - (void)tiledLayer:(AGSTiledLayer *) layer operationDidGetTile:(NSOperation *) op
       {
            return;
       }
i can not find any bug in source code, I'll be much appreciated any point from anyone!

Okay..so you're looking for offline tiled layer. You should use AGSLocalTiledLayer instead of AGSTiledMapServiceLayer. Please see conceptual documentation and sample.

You are not suppose to set the tileDelegate. Here is the API reference doc of this property. The UIView<AGSLayerView>* lyr in your code becomes the tileDelegate by default, which you are not suppose to replace. Hence, you are not seeing the map.

- (id<AGSTiledLayerTileDelegate>) tileDelegate [read, write, assign]
Delegate to be notified when a tile is retrieved asynchronously. When this layer is loaded, a corresponding View object is automatically set as the tileDelegate which should not be replaced.

Hope this helps!

Thanks for your response, it's much appreciated. but I also want to ask again�?if I want get tiles when displaying base map,how can I do? or when displaying base map, I can't get tiles by the flow delegate method?
- (void)tiledLayer:(AGSTiledLayer *) layer operationDidGetTile:(NSOperation *) op

I would like to know why you want to listen to operationDidGetTile method? What is the intention? What you want to do with it?

Thanks Mr Nimesh! I want to develop a app that can automatically save tile images from base map layer to a Sqlite database, when the net was disconnected I can browse the map get from database. As a app(C#) specified by the flow URL:
