Delegate et imagePickerController
Bonjour à tous,
je pense qu'il n'est pas nécessaire de vous dire que je viens de commencer le développement parce que vous allez vite vous rendre compte :)
Comme premier projet après bien sur avoir lu pas mal de cours de base je me lance dans le développement d'une application iPhone.
Principe de l'application :
1- Démarre avec une screenSplash : OK
2- Après 2 seconde je fais appel al la camera avec un overlayview : OK
3- Apres 5 secondes je déclenche la prise de photo automatiquement: KO
Vues de l'application :
Vue de base et une vueOverlay qui contient une image sous forme de cible
mon problème c'est que je ne sait pas trop ou mettre la fonction de capture automatique pour qu'elle envoi l'image au premier ecran sans passer par un boutton
J'ai trouvé pas mal d'exemple (apple inclus) mais tous propose un bouton au niveau de l'écran OverlayView
voici le code la vue de base:
