J'ai quelques questions, aidez-moi s'il vous plaît.Comment déplacer pageviewcontroller de la cellule tactile
Je souhaite déplacer le contrôleur de vue de UIPageViewController si je touche CollectionViewCell sur le protocole DelegSelectItemAt Delegate. S'il vous plaît aidez-moi comment écrire ou modifier le code ci-dessous.
Merci.
