Qu'est-ce que j'ai fait de mal? Je viens de modifier un peu le code de l'application Navigation Based pour lire et afficher une chaîne JSON. Il se bloque lorsque je fais défiler la liste avec le message Objc_msgSend et pointe le problème comme suit: cell.textLabel.text = [[emplacements objectAtIndex: storyIndex] objectForKey: @ "title"];iPhone: demande de cellule pour des lignes en dehors des limites
