Tiles and Data Sources
A typical organization for deep zoom map tiles consists of a folder for each zoom level and individual JPG files for each tile. You can see an example of such files here. ARTiledImageView comes with a local ARLocalTiledImageDataSource, which retrieves tile files from local storage, and a remote ARWebTiledImageDataSource data source, which retrieves map tiles from a remote URL and stores them in Library/Caches (NSCachesDirectory).
ARTiledImageView is available through CocoaPods, to install it simply add the following line to your Podfile:
Try it out with CocoaPods also,
