[ObjC] Récupérer une valeur depuis un scan dans une autre vue
Bonjour,
Je code en ObjC afin de créer une petite application IPhone à titre privé.
J'arrive à scanner des QR-Code qui me rendent des chiffres.
Il faut que je passe ce chiffre dans une autre vue afin de le placer dans une url.
Cependant, je n'y arrive pas… j'ai essayé de faire des méthodes get et de les récupérer mais pas moyen.
Voici mon code:
Ici j'arrive a savoir quel chiffre a été scanner depuis le QR-code.
