MGLSymbolStyleLayer

@interface MGLSymbolStyleLayer : MGLVectorStyleLayer

A symbol layer which allows customization of styling properties at runtime. You may instantiate a new symbol layer to add to a map style or you may query an MGLMapView for its style and obtain existing layers using the -[MGLStyle layerWithIdentifier:] method.
