MLNComputedShapeSource class

MLNComputedShapeSource is a map content source that supplies vector shapes, one tile at a time, to be shown on the map on demand. You implement a class conforming to the MLNComputedShapeSourceDataSource protocol that returns instances of MLNShape or MLNShape, then add a computed shape source to an MLNStyle object along with an MLNStyle object. The vector style layer defines the appearance of any content supplied by the computed shape source.

MLNComputedShapeSource is similar to MLNComputedShapeSource but is optimized for data sets that change dynamically or are too large to fit completely in memory. It is also useful for data that is divided into tiles in a format other than Mapbox Vector Tiles. For GeoJSON data, use the MLNShapeSource class. For static tiles or Mapbox Vector Tiles, use the MLNVectorTileSource class.

You can add and remove sources dynamically using methods such as MLNStyle/addSource: and MLNStyle/sourceWithIdentifier:. This class cannot be represented in a style JSON file; you must add it ot the style at runtime.
