Comment analyser cette sortie JSON imbriquée dans Objective C?

Question

Je suis en train d'analyser une sortie JSON imbriqué comme celui-ci dans l'objectif C:

{ 
-Status: { 
code: 200 
request: "geocode" 
name: "1.304044,103.833867" 
} 
-Placemark: [ 
-{ 
-Point: { 
-coordinates: [ 
103.834 
1.30396 
0 
] 
} 
-AddressDetails: { 
-Country: { 
CountryName: "Singapore" 
-Thoroughfare: { 
ThoroughfareName: "Bus stop at Lucky Plaza (09048)" 
} 
CountryNameCode: "SG" 
} 
Accuracy: 9 
}

address: "Bus stop at Lucky Plaza (09048)" 
}

}

}

}

} 
id: "p4" 
address: "291 Orchard Road, Singapore 238860" 
} 
-{ 
-Point: { 
-coordinates: [ 
103.834 
1.30491 
0 
] 
} 
-AddressDetails: { 
-Country: { 
CountryName: "Singapore" 
AddressLine: "Kimsia Park" 
-Thoroughfare: { 
-PostalCode: { 
PostalCodeNumber: "228968" 
} 
ThoroughfareName: "1 Jalan Kayu Manis" 
} 
CountryNameCode: "SG" 
} 
Accuracy: 9 
} 
id: "p5" 
address: "Kimsia Park, 1 Jalan Kayu Manis, Singapore 228968" 
} 
] 
} 

J'ai un code de travail, mais je trouve la nature imbriquée de cela est assez difficile à comprendre. Ce que je voudrais sortir est un tableau/dictionnaire qui contient les éléments suivants pour chaque enregistrement de retour: coordonnées, CountryName, ThoroughfareName, PostalCode et Précision.

Voici mon code de test à ce jour:

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    NSURL *jsonURL = [NSURL URLWithString:@"http://gothere.sg/maps/geo?output=json&ll=1.304044%2C103.833867&client=&sensor=false&callback="]; 

    NSString *jsonData = [[NSString alloc] initWithContentsOfURL:jsonURL]; 

    self.jsonArray = [jsonData JSONValue]; 

    NSLog(@"%@", jsonArray); 

    [jsonURL release]; 
    [jsonData release]; 
} 

Mon code gère juste pour obtenir la sortie JSON brute, toute pensée/code pour le décomposer comme je l'ai mentionné ci-dessus.

Merci!

Comme demandé, quelques informations supplémentaires.

1. Utilisation de l'infrastructure SBJson.

2. sortie NSLog d'en haut:

Answer 1

Essayez ceci:

//NSMutableArray *addressDetails = [[NSMutableArray alloc] init]; 
NSMutableArray *addressDetails = [[jsonArray valueForKey:@"Placemark"] valueForKey:@"AddressDetails"]; 

    //NSMutableArray *point = [[NSMutableArray alloc] init]; 
NSMutableArray *point = [[jsonArray valueForKey:@"Placemark"] valueForKey:@"Point"]; 

NSLog(@"%@", point); 
NSLog(@"%@", [point objectAtIndex:0]); 

NSLog(@"%@", addressDetails); 

Comme sage, vous pouvez obtenir tableau de "id" et la valeur "adresse" aussi.

Pour obtenir la valeur de "coordonnées" du réseau de points, faire

NSLog(@"%@", [[point objectAtIndex:0] valueForKey:@"coordinates"]); 

Pour addressdetails/Pays/CountryName:

NSLog(@"%@", [[[addressDetails objectAtIndex:0] valueForKey:@"Country"] valueForKey:@"CountryName"]);

Votre JSON est invalide, essayez de le tester sur http://jsonviewer.stack.hu/ une fois becames valide alors seulement vous pouvez l'utiliser. Vous devez avoir utilisé le framework SBJSON pour l'analyser.
