Question

Using cocos2d for iPhone game development, I am confused between Layer and Scene. For example, My simple game have several ‘UI Pages’ like main menu, highscores, game board etc.

So should I use Layer or Scene for every ‘UI page’, and why?

Answer 1

Reviewing SpritesDemo.m/.h, it would appear that they are using Layer, and then creating new scenes, attaching the layer and then replacing the scene on the director

@interface SpriteDemo : Layer @interface SpriteManual : SpriteDemo 

The code then does the following:

-(void)nextCallback:(id)sender {   Scene *s = [Scene node];   [s add: [nextAction() node]];   [[Director sharedDirector] replaceScene s]; } 

So, in short, the answer to your question would be ‘both’, you use Layer to represent your actual ‘UI Page’, but you attach the Layer to a new scene and replace the current scene in the director.
