As in Cocos2d 3.1, if you do not call super in overloading these lifetime methods, the compiler warns you-this can save us a lot of debugging time.

How can you be curious about how this is done?

Cocos2d uses a very good compiler feature diagram to implement this requirement.

You simply add a corresponding __attribute__ keyword to the definition of the method:

-(void) onEnter __attribute__((objc_requires_super));
