全部 ...

我整个周末都在这个问题上，问题仍然存在。我不知道还能做什么，任何帮助将不胜感激。我正在尝试像这样发送 JSON：

 { 
    "proof": 
    {
      "name":"fluff",
      "media_type":"Photo",
      "description":"This is a description"
    },
    "auth_token":"mphxNcEGJMJyU7iPmaLw"
 }

我不断从 RestKit 收到以下异常：

2012-07-23 10:29:17.001 restkittest[8389:707] *由于未捕获的异常“NSUnknownKeyException”而终止应用程序，原因：“[valueForUndefinedKey:]：此类不符合密钥 auth_token 的密钥值编码。”

我怀疑这是因为 auth_token 不是我要传递的对象（证明）的一部分，但我不知道如何将 auth_token 与证明一起传递，因为 postObject 只需要一个对象来发布。

...这是我尝试这样做的代码：

@implementation proof
@synthesize name;
@synthesize description;
@synthesize media_type;
@synthesize duration;
@synthesize frequency_id;
@end

@implementation auth_token
@synthesize auth_token;
@end

- (BOOL)createProof:(proof *)proof
{
    BOOL ret = NO;

    [self.objectManager postObject:proof usingBlock:^(RKObjectLoader *loader)
     {
         loader.delegate = self;

         RKObjectMapping *proofMappingAccept = [RKObjectMapping mappingForClass:[proof class]];
         [proofMappingAccept mapKeyPath:@"name" toAttribute:@"name"];
         [proofMappingAccept mapKeyPath:@"description" toAttribute:@"description"];
         [proofMappingAccept mapKeyPath:@"media_type" toAttribute:@"media_type"];
         [proofMappingAccept mapKeyPath:@"duration" toAttribute:@"duration"];

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

         [mapping mapKeyPath:@"auth_token" toAttribute:@"auth_token"];
         [mapping mapKeyPath:@"proof" toRelationship:@"proof" withMapping:proofMappingAccept];

         loader.serializationMapping = [mapping inverseMapping];

         loader.objectMapping = mapping;
     }];

    return ret;
}

创建一个 NSDictionary，将您的证明对象作为键“proof”的值，将 auth_token 作为键“auth_token”的对象，并将 loader.sourceObject 设置为该字典。
