Probably a little bit late but I was searching for a similar thing. I found this great Tutorial which explained everything: http://www.raywenderlich.com/2343/how-to-drag-and-drop-sprites-with-cocos2d

- (void)ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event {       
    CGPoint touchLocation = [self convertTouchToNodeSpace:touch];

    CGPoint oldTouchLocation = [touch previousLocationInView:touch.view];
    oldTouchLocation = [[CCDirector sharedDirector] convertToGL:oldTouchLocation];
    oldTouchLocation = [self convertToNodeSpace:oldTouchLocation];

    CGPoint translation = ccpSub(touchLocation, oldTouchLocation);    
    CGPoint newPos = ccpAdd(mySpriteToMove.position, translation);
    mySpriteToMove.position = newPos;
}
