sprite kit: verify if touch is inside a node - ios

Question

I'm trying to figure out how to detect if I touch a node in sprite kit. I thought it was function like this in UIView:
[myView pointInside:point withEvent:nil];
But so far I can not have found an alternative to this. What I'm trying to accomplish is to know I have touch the sprite node in the screen.
I'll really appreciate if you can help me to I acomplish this
Here is what I have in my code. I'm adding animated node:
-(void)addMyNodeAnimated
{
NSMutableArray *myNodeArray = [NSMutableArray array];
NSArray *animatedFrames = [NSArray new];
SKTextureAtlas *AnimatedAtlas = [SKTextureAtlas atlasNamed:#"pc2"];
int numImages = (int)AnimatedAtlas.textureNames.count;
for (int i=1; i <= numImages; i++) {
NSString *textureName = [NSString stringWithFormat:#"%#-%d", #"pc2", i];
SKTexture *temp = [AnimatedAtlas textureNamed:textureName];
[myNodeArray addObject:temp];
}
animatedFrames = myNodeArray;
SKTexture *temp = animatedFrames[0];
SKSpriteNode *animationNode = [SKSpriteNode spriteNodeWithTexture:temp];
animationNode.position = CGPointMake(CGRectGetMidX(self.frame), CGRectGetMidY(self.frame));
animationNode.userInteractionEnabled = YES;
animationNode.name = #"AnimationNode";
[self addChild:animationNode];
[animationNode runAction:[SKAction repeatActionForever:
[SKAction animateWithTextures:animatedFrames
timePerFrame:0.1f
resize:NO
restore:YES]] withKey:#"AnimationRuning"];
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
CGPoint _touchLocation = [[touches anyObject] locationInNode:self];
SKNode *node = [self nodeAtPoint:_touchLocation];
if (node != nil)
{
NSLog(#"node name %#", node.name);
}
}
When I touch the node in the screen the node returns null.
Any of know why is this?

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];
if ([node.name isEqualToString:#"yourSpriteName"] && [node.name isEqualToString:#"yourEffectName"]) {
//Whatever you want.
}
}
