I am writing an app in cocos2d. I hava a sprite and a text in my scene. I have written two separate classes for sprite and text. And I added both of them to another class.
In sprite class I have written

- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

And in text class I have written

-(void) registerWithTouchDispatcher
{

[[CCTouchDispatcher sharedDispatcher]addTargetedDelegate:self priority:0 swallowsTouches:YES]; }

-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
 return YES;
}

-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{

NSLog(@"Recognized tOuches in Instructions");// CGSize windowSize = [[CCDirector sharedDirector] winSize]; CCNode *node = [self getChildByTag:kTagNode]; [node setPosition: ccp(text1.contentSize.width/2,text1.contentSize.height/2 - windowSize.height)];

}

-(void) ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event

{

CGPoint touchLocation = [touch locationInView: [touch view]]; CGPoint prevLocation = [touch previousLocationInView: [touch view]];

touchLocation = [[CCDirector sharedDirector] convertToGL: touchLocation]; prevLocation = [[CCDirector sharedDirector] convertToGL: prevLocation];

CGPoint diff = ccpSub(touchLocation,prevLocation);

CCNode *node = [self getChildByTag:kTagNode]; CGPoint currentPos = [node position]; [node setPosition: ccpAdd(currentPos, diff)];

}

But, only touches in the text are recognized and touch of sprite is not recognized ? How can I differentiate the two touches.
