RestKit RKDynamicObjectMapping 仅适用于第一个 JSON 结果 [英] RestKit RKDynamicObjectMapping work only for first JSON result

问题描述

我遇到了 RKDynamicObjectMapping 的问题，但它可能是我滥用它.

i got into an issue with RKDynamicObjectMapping, however it could be that i misuse it.

我有以下场景

1. 请求服务获取区域
2. 选择区域
3. 请求服务获取所选区域的期刊

两个调用返回的数据看起来像这样

data returned by both calls looks like that

{ d: [{cutID:""}, {cutID:""}, {cutID:""}] } 
{ d: [{journalID:""}, {journalID:""}, {journalID:""}] } 

我有以下代码

RKObjectMapping* cutMapping = [RKObjectMapping mappingForClass:[Cut 
class]]; 
[cutMapping mapKeyPath:@"CutID" toAttribute:@"cutID"]; 
RKObjectMapping* journalMapping = [RKObjectMapping mappingForClass: 
[Journal class]]; 
[journalMapping mapKeyPath:@"journalID" toAttribute:@"journalID"]; 
RKDynamicObjectMapping * dynamicMapping  = [RKDynamicObjectMapping 
dynamicMapping]; 
[dynamicMapping setObjectMapping:journalMapping 
whenValueOfKeyPath:@"__metadata.type" isEqualTo:@"JournalDetails"]; 
[dynamicMapping setObjectMapping:cutMapping 
whenValueOfKeyPath:@"__metadata.type" isEqualTo:@"Cut"]; 
[[[RKObjectManager sharedManager] mappingProvider] 
setMapping:dynamicMapping forKeyPath:@"d"]; 

.... 

[objectManager loadObjectsAtResourcePath:getResourcePath 
delegate:self]; 

.... 

以后

[objectManager loadObjectsAtResourcePath:getResourcePath 
delegate:obj]; 

返回 Cut 对象的第一个请求的结果被完美地映射，但对于返回 Journal 对象的第二个请求的结果则没有.登录 request:didLoadResponse 显示服务返回预期的 json ，所以问题在于映射如何使它与两个映射一起工作?

results of first request, which returns Cut objects, is mapped flawlessly, but not for second which returns Journal objects. logging in request:didLoadResponse showed that service returns expected json , so the issue is with mappings how to make it work with two mappings ?

有人在使用 RestKit 动态映射吗?

Anyone using RestKit Dynamic Mapping yet ?

推荐答案

我想您已经检查过您的 Cut 对象在CoreData 实体?

I presume you've checked that your Cut object is mapping to a to-many relationship in the CoreData entity?

如果可以，您可以打开 RESTKit 日志记录并发布结果

If so can you turn on the RESTKit logging and post the results
