#TiledLayer
TiledLayer is a replacement for iOS CATiledLayer, with many extra features:
- different scaling factors for x and y directions
- choose your own scaling steps (instead of only x2)
- any layout of tiles possible
- non-square tiles, different size tiles in one layer
- match the scaling factor to the native resolution of your tiles
- set a margin to load tiles just outside of the visible ones
- you get notified when a tile is no longer needed
- allow 'crisp' tiles: create tiles that have the same resolution as the screen
The tiles are actually objects: they must be, or derive from the Tile class,
which is itself a CALayer. You create a class implementing the
TileProvider interface and register that with the TiledLayer. This
TileProvider is called by the TiledLayer every time a new tile is needed.
The TileProvider has full control over how the tiling is done, how big
the tiles are, what their native scale is, etc. The TiledLayer simply says
"give me a tile that covers this point in the world".
And it will keep requesting tiles like that until the visible area is
filled.
There is also a StandardTileProvider that uses zoom scales with a factor two.
The header files have more documentation.
A small ViewController class is included that shows a basic way of using
the classes. In that one, the background of the tiles changes with
zoom scale, so it is easy to see when it swaps to new tiles.
