RESTKit-Ausnahme: Bei den gesuchten Schlüsselpfaden wurden keine abbildbaren Objektdarstellungen gefunden

Question

Ich stehe vor einem Problem. Der Server hat die Anforderung erhalten, die Zuordnung wurde jedoch nicht korrekt verarbeitet. Ich verstehe nicht, was ich falsch mache.

Code:

    [objectMapping addAttributeMappingsFromArray:@[@"success", @"errors"]]; 
    [objectMapping addPropertyMapping:[RKRelationshipMapping

     NSLog(@"success"); 
    } failure:^(RKObjectRequestOperation *operation, NSError *error) { 
     NSLog(@"failure"); 
    }]; 

ResponseModel Schnittstelle:

@interface ResponseModel : NSObject 

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

@end 

Anfrage:

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

Warum RESTKIT immer Fehlerblock aufrufen?

Answer 1

Möglicherweise müssen Sie nur diese Zeile ändern, da es so aussieht, als würden Sie einen Antwortdeskriptor ohne Antwort einstellen?

[objectManager addResponseDescriptor:self.responseDescriptor]; 

So die self. entfernen, weil es die Instanz-Variable nicht scheint, dass Sie nur eine lokale Variable haben.

verwenden Sie auch method:RKRequestMethodPOST aber die Anfrage mit getObjectsAtPath machen so versagt RestKit GET mit POST übereinstimmen.
