J'écris une application pour interagir avec un récepteur DirecTV via l'interface du serveur http. Je suis en mesure d'interroger l'appareil et obtenir la réponse formatée SJON.La conversion de NSMutableData à NSString échoue si un caractère spécial est présent
Voici mon exemple de code:
- (NSDictionary *) readDVRData
{
NSMutableData *rData = [[NSMutableData alloc] initWithContentsOfFile:@"./data"];
//NSLog(@"rData = %@",rData);
NSString *rString = [[NSString alloc] initWithData:rData encoding:NSUTF8StringEncoding];
NSLog(@"rString = %@",rString);
NSError *error;
SBJSON *json = [[SBJSON new] autorelease];
NSDictionary *response = [json objectWithString:rString error:&error];
//NSLog(@"response = %@",response);
return response;
}
Pour des fins de test, j'ai sauvé la réponse au fichier de données et je lis dans l'exemple ci-dessus. La conversion de NSMutableData à NSString via:
NSString *rString = [[NSString alloc] initWithData:rData encoding:NSUTF8StringEncoding];
échoue si le caractère suivant est en place. È comme dans CrÈme Fraiche. Pour référence, c'était dans l'épisode Titre et la description d'un enregistrement de South Park.
Si je remplace ce caractère par un "E" majuscule, la conversion fonctionne. Y a-t-il une méthode différente que je devrais utiliser pour attraper quelque chose comme ça? Ou y a-t-il un moyen simple de supprimer des caractères comme celui-ci? S'il vous plaît gardez à l'esprit que je ne saurai pas à la main si c'est la marque et l'accent ou quelque chose de différent qui pourrait entraîner l'échec de la conversion.
Merci, Dave
Snippet du fichier de données si cela est nécessaire. J'inclurais le texte entier, mais il pousse la limite de caractères au-dessus de la limite 30000.
