MISE À JOUR:
D'une certaine manière, il l'interprète comme une liste de propriétés Le format semble être similaire à. le format NeXTSTEP original avec =;
Merci Tommy! Vous avez déjà répondu à ma question. J'ai été confus par l'impression de NSLog, mais en fait, comme vous l'avez souligné si vous utilisez NSUTF8StringEncoding, vous obtenez une impression json valide. J'ai juste dû faire face aux touches 'state' et 'results' et votre solution fonctionne: NSArray * results = [feedDictionary objectForKey: @ "results"]; NSArray * addressComponents = [[objet de résultat objectAtex: 0] objectForKey: @ "address_components"]; \t pour (composant NSDictionary * dans addressComponents) { \t \t NSLog (@ "% @", [component objectForKey: @ "long_name"]); \t} – Zsolt
