Ensuite à un moment tu as mis directement [NSMutableString initWithString:...], or "NSMutableString" est une classe, et "initWithString" est une méthode d'instance (donc à appeler sur un objet) et non une méthode de classe. On n'appelle jamais directement "init" sur une classe, on passe par alloc + init, ce qui donne [[NSMutableString alloc] initWithString:...]. Et si tu fais ça, il ne faut alors pas oublier de balacer le "alloc+init" par un "release" à faire plus tard quand tu n'as plus besoin de ta variable (ou un autorelease).
