Problème PathforResource avec un fichier .ics, objectif C

Question

Je suis en train d'apprendre la programmation en Objective C et je me suis retrouvé coincé avec l'obtention de l'information d'un fichier .ics sur ma tableview.

La vue de la table fonctionne bien. Je l'ai essayé avec des informations stockées directement dans NSArray. Je reçois une vue détaillée des informations en cliquant sur les en-têtes. Lorsque j'essaie d'obtenir les informations du fichier .ics, les en-têtes n'apparaissent même pas. Je viens d'avoir une fenêtre vide.

Je suppose que votre problème est le suivant:

NSString *path = [[NSBundle mainBundle] pathForResource:@"timeedit" ofType:@"ics"]; 
NSDictionary *dict = [NSDictionary dictionaryWithObject: path forKey:@"Calendar app"]; 

Un fichier iCal (.ics) n'est pas un fichier xml sous forme de liste de biens, ce qui signifie que cela devrait revenir nil. Vous devriez trouver une façon différente de lire les fichiers iCal.
