RestKit

Question

我希望使用 restkit 映射以下 JSON。

"ObjectDetails":
[
  {
    "ObjectName":"Test1",
    "Properties":
    {
      "PropertyName1":1,
      "PropertyName3":2
    }
  },
  {
    "ObjectName":"Test2",
    "Properties":
    {
      "PropertyName1":1,
      "PropertyName2":"asdf"
    }
  },
  {
    "ObjectName":"Test3",
    "Properties":
    {
      "PropertyName1":1,
      "PropertyName6":3423,
      "PropertyName7":"test",
      "PropertyName3":2
    }
  }
]

对象

@interface ObjectDetail : NSObject
@property (nonatomic, strong) NSString *objectName;
//????
@end

映射

RKObjectMapping* mapping = [RKObjectMapping mappingForClass:[ObjectDetail class]];
[mapping addAttributeMappingsFromDictionary:@{@"ObjectName":@"objectName"}];

RKResponseDescriptor *rd = [RKResponseDescriptor responseDescriptorWithMapping:mapping method:RKRequestMethodAny pathPattern:nil keyPath:@"ObjectDetails" statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

我的问题是 'Properties' 具有动态属性。我还没有找到将属性映射到任何东西的方法。理想情况下，最好将 Properties 映射到 key/value 字典。我确实需要字段名称和值。

即

@interface ObjectDetail : NSObject
@property (nonatomic, strong) NSString *objectName;
@property (nonatomic, strong) NSMutableDictionary *properties;
@end

有没有人知道这个的解决方案或知道如何实施它？

更新：基于@Idali 解决方案，非常简单。如果您觉得有帮助，请务必为他们的回答点赞！

对象

@interface ObjectDetail : NSObject
@property (nonatomic, strong) NSString *objectName;
@property (nonatomic, strong) id *properties;
@end

映射

RKObjectMapping* mapping = [RKObjectMapping mappingForClass:[ObjectDetail class]];
[mapping addAttributeMappingsFromDictionary:@{@"ObjectName":@"objectName", @"Properties": @"properties"}];

那就施放吧

self.myDictionnay  = (NSDcitionnary*) objectDetail.properties;

Answer 1

您可以通过在核心数据中将 "properties" 属性设置为 transformable 类型并在您的 ObjectCalss 中将其声明为 id 并映射它来解决它。如果您创建 ManagedObject 子类，它将是：

@property (nonatomic, retain) id properties;

要阅读您可以投射的内容： .... ....

NSArray *fetchedObjects = [context executeFetchRequest:fetchRequest error:&error]; ObjectDetail* objectDetail =[fetchedObjects firstObject]; self.myDictionnay = (NSDcitionnary*) objectDetail.properties; NSArray* keys = [self.myDictionnay allKeys]; //to check for existence of any key
