This version has a working tiled image and working tab bar.
Added bus tiles. Bug where zooming out bus map disappears. Still can’t set zoom rectangle.
Got the bus tiles to work with even number for width and multiple of 8 (256) for height, tiles set to size 256. would it work better if height was multiple of 256? maybe….
Subway tiles would have to be refactored unless I rewrite the classes to take a maxScale … may investigate a custom tiler that replaces apple’s buggy CATileLayer
