if I set the tileSize property of MKTileOverlay to tileSize=CGSizeMake(1024, 1024). the mapViewer shows my tiles all over the view with gaps and in the wrong order. I have produced tiles that are in the dimension 1024 x 1024.
zoom level 1 has 4 png tiles, zoom level 2 has 16 png tiles, zoom level 3 has 64 png tiles
if I set MKTileOverlay.tileSize=CGSizeMake(256, 256) and provide 256x256 tiles everything works fine?
what could be the problem?
