This class was originally written by DK101
http://dk101.net/2010/11/30/implementing-page-scrolling-in-cocos2d/

It is a very clean and elegant subclass of CCLayer that lets you pass-in an array of layers and it will then create a smooth scroller. Complete with the "snapping" effect. You can create screens with anything that can be added to a CCLayer.

It is mostly the same with the following changes:

- updated to work with Cocos2d 0.99.5
- added the option to change the width of each layer for the "Angry Birds" style preview effect
- removed CCTouchDispatcher on exit (this was messing up touch events on other scenes)

USAGE:

1. add both files to your project
2. in your scene import CCScrollLayer.h
3. in your scene's init method construct each layer and pass it to the CCScrollLayer class:

e.g.

// get screen size
CGSize screenSize = [CCDirector sharedDirector].winSize;

/////////////////////////////////////////////////
// PAGE 1
////////////////////////////////////////////////
// create a blank layer for page 1
CCLayer *pageOne = [[CCLayer alloc] init];

// create a label for page 1
CCLabelTTF *label = [CCLabelTTF labelWithString:@"Page 1" fontName:@"Arial Rounded MT Bold" fontSize:44];
label.position =  ccp( screenSize.width /2 , screenSize.height/2 );

// add label to page 1 layer
[pageOne addChild:label];

/////////////////////////////////////////////////
// PAGE 2
////////////////////////////////////////////////
// create a blank layer for page 2
CCLayer *pageTwo = [[CCLayer alloc] init];

// create a custom font menu for page 2
CCLabelBMFont *tlabel = [CCLabelBMFont labelWithString:@"Page 2" fntFile:@"customfont.fnt"];
CCMenuItemLabel *titem = [CCMenuItemLabel itemWithLabel:tlabel target:self selector:@selector(testCallback:)];
CCMenu *menu = [CCMenu menuWithItems: titem, nil];
menu.position = ccp(screenSize.width/2, screenSize.height/2);

// add menu to page 2
[pageTwo addChild:menu];
////////////////////////////////////////////////

// now create the scroller and pass-in the pages (set widthOffset to 0 for fullscreen pages)
CCScrollLayer *scroller = [[CCScrollLayer alloc] initWithLayers:[NSMutableArray arrayWithObjects: pageOne,pageTwo,pageThree,nil] widthOffset: 230];

// finally add the scroller to your scene
[self addChild:scroller];


Enjoy :)
