ici mon codeUn problème avec l'objet de libération
- (UIImageView *)createImageView:(NSUInteger)inImageIndex
{
UIImageView * result = [[UIImageView alloc] initWithImage:[mImages objectAtIndex:inImageIndex]];
result.opaque = YES;
result.userInteractionEnabled = NO;
result.backgroundColor = [UIColor blackColor];
result.contentMode = UIViewContentModeScaleAspectFit;
result.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
return [result autorelease];
}
cette méthode appellera par init 3 fois mais pas l'erreur lorsque je tente de glisser l'image de cette méthode fera appel à nouveau et a obtenu une erreur
objc [962]: lIBÉRÉ (id): communiqué de message envoyé à l'objet libéré = 0x3b37860
note: si je ne libère résultat ne sera pas l'erreur mais je vais obtenir une fuite de mémoire
comment puis-je le réparer?

ici est créer une matrice d'une autre classe et envoyer à mImages = [inImages retain]

Pourriez-vous publier le code dans lequel vous créez le tableau mImages et formater le code correctement? – FelixLam
Ne pas libérer AppDelegate – nduplessis
AppDelegate = [[délégué UIApplication sharedApplication]]; est ce code retenir je pense qu'il allouer un objet – RAGOpoR
