Zoom sur un champs de texte

Bonjour,



voila le problème, j'ai mis en place une vue via mon storyboard comprennent deux champs de texte. Le soucis est que une fois le curseur sur l'un de mes champs de texte, le claviers le recouvre largement. Du coup je voulais vous demandez comment mettre en place un système permettant de zoomer sur le champ de texte une fois le curseur dessus, a fin qu'il soit visible juste au dessus du clavier. Mais également qu'il dézoome une fois que le clavier disparaà®t.



Merci de votre aide

    Du coup quand j'affiche le clavier, rien se passe, il recouvre mon 3éme champ de texte, comme avant et j'arrive pas à  scroller pour y accéder.

    Tu devrais sûrement déclarer dans ton .h que ta classe implémente UITextFieldDelegate
