SpriteKit -use of AppDelegate - undeclared identifier

I'm writing the game in cocos2d (from Pablo Ruiz's book). Right now I have to create pause screen, and, according to the book, I have to create new function in AppDelegate.m (and in .h file) :

+(AppDelegate *) get {

return (AppDelegate *) [[UIApplication sharedApplication] delegate];
}

I'm getting errors : Expected a type; expected expression; Missing '[' at start of message send expression; Use of undeclared identifier 'AppDelegate'.

In another file, called GameScene.m, I created those functions:

-(void)resume
{
if(![AppDelegate get].paused)
{
    return;
}
[AppDelegate get].paused = NO;
[self onEnter];
}

-(void)onExit
{
if(![AppDelegate get].paused)
{
    [AppDelegate get].paused = YES;
    [super onExit];
}
}

-(void)onEnter
{
if(![AppDelegate get].paused)
{
    [super onEnter];
}
}

And I'm getting another set of errors : Use of undeclared identifier 'AppDelegate', four times.

Can someone explain me how to get rid of those errors?

Cocos2d 2.0? Then Use AppController.

#import "AppDelegate.h"

AppController *app = (AppController*)[UIApplication sharedApplication].delegate;

Make sure you have added the following to your GameScene.h:

@class AppDelegate;

This will let the compiler know that the class AppDelegate exists. And in your GameScene.m:

#import "AppDelegate.h"

This lets you access AppDelegate members and methods.
