Question

我希望使用restkit映射以下JSON。

Application

对象

"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
    }
  }
]

映射

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

我的问题是'属性'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，将Properties映射到键/值字典会很不错。我确实需要字段名称和值。

即

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

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

有没有人知道这方面的解决方案或知道如何实现它？

更新：基于@Idali解决方案，非常简单。如果您发现这有用，请务必提供答案！

对象

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

映射

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

然后投下它。

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

您可以通过设置＆＃34;属性＆＃34;来解决它。在coredata中输入transformable属性，并在ObjectCalss中将其声明为id并映射它。如果您创建ManagedObject子类，它将为：

@property (nonatomic, retain) id properties;

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
