A SKEmitterNode object is a node that automatically creates and renders small particle sprites. Particle sprites are privately owned by Sprite Kit—your game cannot access the generated sprites. For example, this means you cannot add physics shapes to particles. Emitter nodes are often used to create smoke, fire, sparks, and other particle effects. Available in iOS 7.0 and later.
