Restkit,映射,没有获取所有值

我想通过restkit加载以下JSON。我正在使用Restkit 0.2.3。

JSON数据:

{
    "meta": {
        "limit": 25,
        "cache-expiry": 3600
    },
    "objects": [
        {
            "name": "TREATmachine",
            "locality": "San Francisco",
            "street_address": "20th & Morrison S.E.",
            "cuisines": [
                "vegan",
                "european"
            ],
            "region": "CA",
            "phone": "(503) 308-8851",
            "postal_code": "94110",
            "categories": [
                "other",
                "restaurant"
            ],
            "has_menu": true,        
        }
    ]
}

现在我为此声明了这个类来处理所有元素

@property (nonatomic, retain) NSString* name;
@property (nonatomic, retain) NSString* locality;
@property (nonatomic, retain) NSString* street_address;
@property (nonatomic, retain) NSArray * cuisines;
@property (nonatomic, retain) NSString* region;
@property (nonatomic, retain) NSString* phone;
@property (nonatomic, retain) NSString* postal_code;
@property (nonatomic, retain) NSArray * categories;
@property (assign) BOOL has_menu;

现在映射就像这样,

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[Location class]];
[mapping addAttributeMappingsFromArray:@[@"name",@"locality", @"street_address", @"region",   
      @"phone", @"postal_code", @"country", @"lat", @"website_url", @"resource_uri"]];
[mapping addAttributeMappingsFromDictionary:@{ @"venueID": @"id"}];

之后我创建了一个

RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor   
        responseDescriptorWithMapping:mapping method:RKRequestMethodGET pathPattern:@"/Locations 
        /search/" keyPath:@"objects" statusCodes:statusCodeSet];

它在获取数据时工作正常,但我遇到的问题是我总是得到一个空的对象,其中没有数据。

我没有收到失败或错误消息,只是空对象。

我错过了什么?

编辑:输入响应描述符代码。

1 个答案:

答案 0 :(得分:0)

在从@Wain获得记录的好主意后,我将以下代码添加到我的视图控制器

  RKLogConfigureByName("RestKit", RKLogLevelWarning); 
  RKLogConfigureByName("RestKit/ObjectMapping", RKLogLevelTrace);
  RKLogConfigureByName("RestKit/Network", RKLogLevelTrace);

它基本上告诉我,我没有正确映射我的数据。

我不知道人们是否有关于跟踪级别映射代码的去向的建议?在哪个文件?的AppDelegate?
