Exception RESTKit: Aucune représentation d'objet mappable n'a été trouvée dans les chemins clés recherchés

Question

Je suis confronté à un problème. Le serveur a reçu la requête mais le mappage n'est pas correctement traité. Je ne comprends pas ce que je fais mal.

interface ResponseModel:

@interface ResponseModel : NSObject 

@property NSString* success; 
@property id data; 
@property (strong, nonatomic) NSArray* errors; 

@end 

Demande:

{ 
    "success": "true", 
    "data": [], 
    "errors": [] 
} 

Pourquoi RESTKIT appelle toujours un bloc de défaillance?

Answer 1

Vous avez peut-être juste besoin de changer cette ligne car il semble que vous définissez un descripteur de réponse nul?

[objectManager addResponseDescriptor:self.responseDescriptor]; 

enlever Ainsi, le self. car il semble que vous ne définissez pas la variable d'instance que vous avez juste une variable locale.

Vous utilisez également method:RKRequestMethodPOST mais qui fait la demande avec getObjectsAtPath si RestKit ne parvient pas à correspondre avec GETPOST.
