How do I callback a function when label is touched in cocos2d-x?
you can't set a callback function for
CCLabelTTF or any other Label class, yet there is CCMenuItemLabel you can use.
you first need to create an instance of
CCMenu class. then you need to allocate
CCMenuItemLabel instance, using
CCMenuItem::initWithLabel (CCNode *label, CCObject *target, SEL_MenuHandler selector). just check how helloworld sample handled it, although it's using CCMenuItemImage, but the base idea is just same in both.
