I have an action that I declared in the -init method.
-(id) init
{
if( (self=[super init])) {
sprite = [CCSprite spriteWithFile:@"Icon@2x.png"];
sprite.position = ccp(150,150);
[self addChild:sprite];
sprite.tag = 13;
self.isTouchEnabled = YES;

CCAction *anAction = [CCBlink actionWithDuration:5 blinks:10];
anAction.tag = 15;
}
return self;
}

Now, I can access the sprite without any problems.
-(void)ccTouchesBegan:(NSSet *)touch withEvent:(UIEvent *)event {

CCNode *node = [self getChildByTag:13];
NSAssert([node isKindOfClass:[CCSprite class]],@"is NOT member of CCSprite");
CCSprite *sprite = (CCSprite *)node;
sprite.scale = CCRANDOM_0_1();

}

Now I don't know how to access my action via tag.. would anyone mind showing me a small example ?

In the code above, the action was autoreleased after your init method returned.

If the sprite were performing the action, you could retrieve it using the getActionByTag method:

myAction = [mySprite getActionByTag: 12345];

but in the code above, the action is long gone.

You'll want to have the sprite run it or else retain it in an ivar or else create it when you need it rather than in your init method.
