使用 restkit 0.23.3 发送多部分：响应映射为空

Question

我正在尝试 post 一个对象（行走）到我的服务器。

[[RKObjectManager sharedManager] postObject:walk path:urlPath
                                 parameters:nil success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
                                     NSLog(@"It Worked: %@", mappingResult );

                                     if(mappingResult.count==0) {
                                         [self alertStatus:@"Error" :@"Erreur" :0];
                                         return;
                                     }...

问题是 mappingResult 总是空的。

在日志中我有以下内容：

2015-01-11 22:49:56.258  XXXX It Worked: <RKMappingResult: 0x1685b750, results={
        }>

我添加了这个 responseDescriptor：

RKResponseDescriptor * descriptor = [RKResponseDescriptor responseDescriptorWithMapping:[ResponseModel defineResponseRequestMapping]
                                             method:RKRequestMethodPOST
                                        pathPattern:nil
                                            keyPath:nil
                                        statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];
[[RKObjectManager sharedManager] addResponseDescriptor:descriptor];

我尝试了不同的 pathPattern，但它不起作用。映射：

RKObjectMapping *mapping = [RKObjectMapping mappingForClass:[ResponseModel class]];

[mapping addAttributeMappingsFromDictionary:@{
                                              @"status":   @"status",
                                              @"reason":   @"reason",
                                              @"message":   @"message",
                                              @"errors":   @"errors",
                                              @"result":   @"result"

                                              }];

任何人都可以帮助我为什么我的 mappingResult 总是空的，即使我从 Restkit 没有错误？

非常感谢您的帮助！

感谢您的留言。我刚刚在 link: RestKit POST response with wrong mapping 上找到了解决方案。

RestKit 对响应使用与请求相同的映射。你必须强迫它。

谢谢
