Je dois exécuter un fil de fond pour obtenir l'image de l'album Facebook. Je dois commencer un diaporama avec la première image collectée. Et je donne un sommeil de 3 secondes mais il ne fonctionne pas. Il existe également une autre méthode pour obtenir l'image de l'URL autre que NSData * data = [NSData dataWithContentsOfURL: url]; méthodeFil d'arrière-plan en cours d'exécution pour récupérer l'image de l'album Facebook
