MkMapView cancel loading google tiles

Question

I have a case where I need to import an overlay map in top of MkMapView. The overlay totally covers the google tiles below so there is no need loading, plus it adds overhead

Answer 1

I encountered a related problem but in my case my overlay didn't cover all the google tiles. If anyone has this problem, and is trying to stop loading the google tiles, I managed to superimpose one gray tile(256x256) overlay over the google map tiles. To do this, the top level tile must be /FakeTiles/1/1/0.png and add this directory to resources to project. (N.B. don't drag this into project > Add files > Folders > Create folder references for any folders)

//hack to overlay grey tiles
NSString *fakeTileDirectory = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"FakeTiles"];
TileOverlay *greyOverlay = [[TileOverlay alloc] initWithTileDirectory:fakeTileDirectory];
[mapView addOverlay:greyOverlay];
[greyOverlay release];

then add your custom tile overlay.

Then you need this code to scale the grey tile Calculating tiles to display in a MapRect when "over-zoomed" beyond the overlay tile set
