Bonjour tout le monde !

Je suis nouveau dans la programmation d'application d'appareil iOS. J'essaie présentement de créer une application iPad qui comportera une page principale (de login) qui mènera à un tabbarcontroller. Une des onglets de ce tabbarcontroller sera un splitviewcontroller. J'ai réussie a créer tout cela en utilisant le storyboard, cependant je n'arrive pas à faire changer le contenu du detailviewcontroller avec le masterviewcontroller. Quand je clique sur la tag qui me conduit au splitview c'est correcte. Cependant, rendu au splitview, quand je clique sur les différentes cellules du tableview, le detailview reste noir.

Merci bien de vouloir m'aider.

Voici le code de mon application :
(Je n'ai pas mis le code pour la classe tree, je ne crois pas que c'est utile pour règler mon problème)
J'ai comme l'impression que c'est peut-être dans AppDelegate le problème, mais comme je vous l'ai dit, je suis nouveau, donc je ne sais pratiquement pas quoi rajouter dans AppDelegate

Bonjour,

J'ai édité le titre de ton sujet pour qu'il soit conforme aux règles du forum "Mobile" et du site (il faut indiquer le plateforme entre crochet et donner un titre explicite "Problème application" n'est pas explicite sur ton problème). J'ai aussi modifier le langage de tes balises code pour le bon langage. Tu ne programmes pas en C# sur iPad.

Merci de faire attention la prochaine fois.

PS : Si le titre ne te convient pas, contact moi par MP. Le forum "Mobile" souffre d'un bug qui empêche les membres de modifier le titre de leurs sujets eux-même.
