J'ai des boutons de défilement horizontal qui vont naviguer vers un autre contrôleur de vue lorsqu'un utilisateur sélectionne le bouton qui fonctionne bien mais le problème survient lorsque l'utilisateur tape sur le bouton, la barre de navigation est cachée.La barre de navigation se chevauche par scrollview horizontal
Il semble que les boutons de défilement horizontal chevauchent la barre de navigation. J'ai écrit ces boutons de défilement par programme.
Il est probable que l'action du bouton de retour soit incorrecte. Comme mentionné ci-dessus, je devrais voir plus de code pour vraiment aider.

Où est les boutons étant ajoutés? Pour quelle vue. –
Vous devez fournir plus d'informations, le code approprié, éventuellement des captures d'écran. Essayez de lire votre question comme si vous n'aviez aucune idée de votre problème. – user5226582
@MartinBorstrand - Les boutons sont ajoutés à homeVC juste en dessous de la barre de navigation. il peut être défiler horizontalement. – Jonathan
