Touch event Cocos2d iPhone - ios

Question

I have doubts about touch event in cocos2d, in particular:
I have two layers:
GameLayer.m
-(id)init
{
if(self=[super init])
{
NSLog(#"GAME");
CCSprite*game=[CCSprite spriteWithFile:#"alien.png"];
CGSize size=[CCDirector sharedDirector].winSize;
self.contentSize=CGSizeMake(50,50);
self.touchEnabled=YES;
game.position=CGPointMake(40,40);
[self addChild:game];
//NSLog(#"%d",[[self children] count]);
//NSLog(#"%f",self.position.x);
}
return self;
}
-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(#"GAME");
}
UserInterfaceLayer.m
-(id)init
{
if(self=[super init])
{
NSLog(#"USER");
self.touchEnabled=YES;
CCSprite*game=[CCSprite spriteWithFile:#"spiders.png"];
CGSize size=[CCDirector sharedDirector].winSize;
self.contentSize=CGSizeMake(20,20);
game.position=CGPointMake(40,40);
[self addChild:game];
//NSLog(#"%d",[[self children] count]);
//NSLog(#"%f",self.position.x);
}
return self;
}
-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(#"USER");
}
Both are children of one scene:
MultiLayerScene.m
-(id)init
{
if(self=[super init])
{
sharedMultiLayerScene = self;
self.contentSize=CGSizeMake(30, 30);
CGSize size=[CCDirector sharedDirector].winSize;
// The GameLayer will be moved, rotated and scaled independently
GameLayer* gameLayer = [GameLayer node];
gameLayer.position=CGPointMake(250,250);
[self addChild:gameLayer z:1 tag:1];
//gamelayerposition = gameLayer.position;
// The UserInterfaceLayer remains static and relative to the screen area.
UserInterfaceLayer* uiLayer = [UserInterfaceLayer node];
uiLayer.position=CGPointMake(-100, -100);
[self addChild:uiLayer z:-1 tag:2];
}
return self;
}
My problem is that I touch on screen at any position their ccTouchesBegan event run.
For example if I touch only on GameLayer runs both the GameLayer touches event and the other.
I try also to insert the two layer in two different position(as you can see from the code) , but the problem still persist.
How Do I resolve this problem?
I would like ,for example,if I touch on Gamelayer respond only its touch event.

Try this
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
Priority: lower number = higher priority.
