解析嵌套动态JSON与RestKit

我试图用RESTKIT解析嵌套动态JSON与RestKit

 

{ 
     "0": { 
      "page": { 
       "url": "http://www.zmtcdn.com/menus/307/1.jpg", 
       "thumb_url": "http://www.zmtcdn.com/menus/307/1_thumb.jpg" 
          } 
      }, 
     "1": { 
      "page": { 
       "url": "http://www.zmtcdn.com/menus/307/2.jpg", 
       "thumb_url": "http://www.zmtcdn.com/menus/307/2_thumb.jpg" 
          } 
      }, 
     "menu_url": "http://www.zomato.com/ncr/restaurants/south-delhi/mathura-road/sagar-ratna-315/menu#tabtop" 
}

类correponding解析以下JSON到这里面我已经做的是： -

@interface ImageCollections : ZomatoObject 

@property (nonatomic, strong) NSString* ignore; 
@property (nonatomic, strong) NSString* keyTerm; 
@property (nonatomic, strong) ImageUrl* menus; 
@property (nonatomic, strong) ImageUrl* photos; 

@end

和相应的实施是

+ (RKObjectMapping *) getObjectMapping 
{ 
    RKObjectMapping *objectMapping = [RKObjectMapping mappingForClass:[ImageCollections class]]; 
    [objectMapping mapKeyPath:@"menu_url" toAttribute:@"ignore"]; 
    objectMapping.forceCollectionMapping = YES; 
    [objectMapping mapKeyOfNestedDictionaryToAttribute:@"keyTerm"]; 
    [objectMapping mapKeyPath:@"(keyTerm).page" toRelationship:@"menus" withMapping:[ImageUrl getObjectMapping]]; 
    return objectMapping; 
}

类似地，对象映射的ImageUrl类是

+ (RKObjectMapping *) getObjectMapping 
{ 
    RKObjectMapping *objectMapping = [RKObjectMapping mappingForClass:[ImageUrl class]]; 
    [objectMapping mapKeyPath:@"url" toAttribute:@"url"]; 
    [objectMapping mapKeyPath:@"thumb_url" toAttribute:@"thumbUrl"]; 
    return objectMapping; 
}

但我得到一个异常

 
*** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ valueForUndefinedKey:]: this class is not key value coding-compliant for the key page.'

请帮助..

什么是翻页键路径正在对评估的价值？你有没有尝试过使用单元测试来执行映射？
