Ci-dessus, ma réponse API.Mappage RestKit avec objet NSDictionary et NSArray
Maintenant je veux cartographier "météo" et "nom" et je veux le même objet en guise de réponse.
Je peux créer à la classe
@interface WeatherStatus : NSObject
@property (nonatomic, copy) NSString *name;
@property (nonatomic, strong) WeatherInfo *info;
@end
et
@interface WeatherInfo : NSObject
@property (nonatomic, copy) NSString *description;
@property (nonatomic, copy) NSString *icon;
ci-dessous est le code de la cartographie.
RKObjectMapping *weatherInfo = [RKObjectMapping mappingForClass:[WeatherInfo class]];
[weatherInfo addAttributeMappingsFromDictionary:@{@"description": @"description", @"icon": @"icon"}];
RKObjectMapping *weatherStatus = [RKObjectMapping mappingForClass:[WeatherStatus class]];
[weatherStatus addAttributeMappingsFromArray:@[@"name"]];
[weatherStatus addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"weather" toKeyPath:@"weather" withMapping:weatherInfo]];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:weatherStatus method:RKRequestMethodGET pathPattern:nil keyPath:@"weather" statusCodes:nil];
[objectManager addResponseDescriptor:responseDescriptor];
NSDictionary *queryParams;
queryParams = [NSDictionary dictionaryWithObjectsAndKeys:kAPP_KEY, @"appid", @"Ahmedabad", @"q", nil];
[[RKObjectManager sharedManager] getObjectsAtPath:@"/data/2.5/weather" parameters:queryParams success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
WeatherStatus *obj = [mappingResult.array objectAtIndex:0];
NSLog(@"info %@",obj.info);
NSLog(@"name %@",obj.name);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(@"What do you mean by 'there is no coffee?': %@", error);
}];
Je reçois
info (null)
name (null)
Quelqu'un peut-il me faire savoir où est l'erreur?
Je l'ai déjà vu RestKit complex and simple JSON RKObjectMapping almost working, but
Je suis confus. http://stackoverflow.com/questions/23529494/restkit-complex-and-simple-json-rkobjectmapping-almost-working-but "emplacement" est dans un format de tableau! – kb920
C'est un tableau de niveau supérieur, non imbriqué. C'est une différence clé. – Wain
J'ai essayé la description comme tableau mais cela n'a pas fonctionné! – kb920
