的嵌套数组。我没有使用RKEntityMapping,只是RKObjectMappings,因为这个应用程序没有使用核心数据。我已经查阅了RestKit wiki上Object Mappings的文档,并在源代码中查看了测试用例中的类似设置,但没有运气。Restkit 0.20我有一个问题,映射使用RestKit 0.20</p> <p>我试图映射的产品及其附件具有下列对象的数组下面的JSON有效载荷对象映射问题

@interface clinProduct : NSObject
@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *description;
@property (nonatomic, retain) NSArray *attachments;
@interface clinAttachment : NSObject
@property (strong, nonatomic) NSString *attachmentID;
@property (strong, nonatomic) NSString *attachmentName;
@property (strong, nonatomic) NSString *type;
这里是我的对象映射和我RKResponseDescriptor
RKObjectMapping *attachmentMapping = [RKObjectMapping mappingForClass:[clinAttachment class]];
[attachmentMapping addAttributeMappingsFromDictionary:@{@"Id" : @"attachmentID",
@"Name" : @"attachmentName",
@"Type" : @"type"}];
RKObjectMapping *productMapping = [RKObjectMapping mappingForClass:[clinProduct class]];
[productMapping addAttributeMappingsFromDictionary:@{@"Description" : @"description",
@"Name" : @"name"}];
RKRelationshipMapping *relationshipMapping = [RKRelationshipMapping relationshipMappingFromKeyPath:@"Attachments"
toKeyPath:@"attachments"
withMapping:attachmentMapping];
[productMapping addPropertyMapping:relationshipMapping];
RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:productMapping
pathPattern:nil
keyPath:@"Result.Product"
statusCodes:[NSIndexSet indexSetWithIndex:200]];
我得到一个有效的响应,但奇怪的是它唯一的映射描述属性的产品,甚至不是它的名字!
2013-03-05 18:39:49.775 iOS[38965:c07] Loaded results: <RKMappingResult: 0x96a8950, results={
"Result.Product" = "Its EVIL!";
当添加的第二响应描述符,向下钻取Result.Product.Attachments,我可以得到附件的阵列仅与附件响应描述符没有问题。任何帮助将不胜感激,自周日下午以来,我一直在抨击这件事。道歉代码墙,但它很难描述RestKit设置完全没有所有的作品。谢谢。
我已经解决了这个问题。首先,我粘贴的RKMappingResult不正确。它映射一个项目,但它只显示其中一个属性。为了使它工作,我删除了产品类中的RKRelationshipMapping和NSAray,并为附件添加了第二个RKResponseDescriptor。一切都在RKMappingResult中正确显示,数组只是不幸地包含异构元素。这是一个黑客,但它终于解决了我的问题。 – 2013-03-10 05:09:30
你可以把它作为答案吗?然后将其标记为答案? – Steven 2013-10-22 18:59:51
