Ошибка неоднозначности класса (неоднозначное преобразование из ведомого класса) С CCStandredTouchDelegate в cocos2dx?

Я делаю подклассы CCSprite, чтобы сделать Жест вращения для объекта спрайта.

Для этого мне нужно использовать CCTargetedTouchDelegate и CCStandardTouchDelegate
Но даже после объявления функций этих делегатов я получаю ошибку неоднозначности.

Снимок экрана ошибки: —

код в моем .h файле.
