ios - 如何在 RestKit 0.20 中接收整数值？

Question

我将对象休息为:

@interface VFEQuestionnaireRest : NSObject
    @property(copy ,nonatomic) NSNumber *iid;
    @property(copy, nonatomic)NSString *namePoll;
    @property(copy, nonatomic)NSSet *questions;
@end

即将到来的 JSON 为:

    {"questionnaire":[
      {"id":4,"namePoll":"questionario4","questions":              
         {"id":13,"idQuestionnaire":4,"nameQuestion":"costo?",
            "questionType":{"id":2,"nameType":"WHOLE"}}}]}

值“iid”始终为“0”，并且namePoll有其正确的值。 如何将 int 值从 JSON 映射到 NSNumber objC？

-

RKObjectMapping *questionnaireMapping = [RKObjectMapping mappingForClass:[VFEQuestionnaireRest class]];
    [questionnaireMapping addAttributeMappingsFromDictionary:
     @{@"iid":@"id",
    @"namePoll":@"namePoll"
     }];
[questionnaireMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"questions" toKeyPath:@"questions"  withMapping:questionMapping]];

我相信您的映射不正确。它应该是源 -> 目的地，而不是相反:

RKObjectMapping *questionnaireMapping = [RKObjectMapping mappingForClass:[VFEQuestionnaireRest class]];
[questionnaireMapping addAttributeMappingsFromDictionary:
   @{ @"id":@"iid",
   @"namePoll":@"namePoll" }];

Restkit 自动执行 int -> NSNumber 转换。
