An SKScene object represents a scene of content in Sprite Kit. A scene is the root node in a tree of Sprite Kit nodes (SKNode). These nodes provide content that the scene animates and renders for display. To display a scene, you present it from an SKView object. SKScene is Apple technology for use on iOS 7.0 and later.

An SKScene object represents a scene of content in Sprite Kit. A scene is the root node in a tree of Sprite Kit nodes (SKNode). These nodes provide content that the scene animates and renders for display. To display a scene, you present it from an SKView object.

A scene calculates the contents of a new frame by processing the following actions in order:

  • The scene calls its update: method.
  • The scene executes actions on its children.
  • The scene calls its didEvaluateActions method.
  • The scene executes any physics simulations on physics bodies in the scene.
  • The scene calls its didSimulatePhysics method.
