Question

提前致谢所有帮助社区!!我有一个早期的问题，这是我指出的，我修复了“[人物对象] - 应该是 - ＆gt; [人员分配]初始化]我修复了它，现在能够将一个Person对象添加到我的服务器。但是这里问题是服务器上的所有值都为空并且它返回1001代码Code = 1001“无法找到keyPath的对象映射：''”UserInfo = 0x5938ce0 {= RKObjectMapperKeyPath，NSLocalizedDescription =无法找到keyPath的对象映射：''} 什么是我错误地映射任何想法？ Noobie在这里，感谢您提供的任何帮助！哦，如果你在社交中，我愿意为这个问题付课。 Thnx再次！

RKObjectMapping* userMapping = [RKObjectMapping mappingForClass:[Person class]];
 [userMapping mapKeyPath:@"updated_at" toAttribute:@"updatedAt"];
[userMapping mapKeyPath:@"created_at" toAttribute:@"createdAt"];
[userMapping mapKeyPath:@"name" toAttribute:@"name"]; 
[userMapping mapKeyPath:@"id" toAttribute:@"personId"];

RKObjectMapping* dogMapping = [RKObjectMapping mappingForClass:[Dog class]];
[dogMapping mapKeyPath:@"created_at" toAttribute:@"createdAt"]; 
[dogMapping mapKeyPath:@"person_id" toAttribute:@"spersonId"]; 
[dogMapping mapKeyPath:@"name" toAttribute:@"name"]; 
[dogMapping mapKeyPath:@"updated_at" toAttribute:@"updatedAt"]; 
[dogMapping mapKeyPath:@"id" toAttribute:@"dogId"]; 

RKObjectMapping *dataMapping = [RKObjectMapping mappingForClass:[Data class]]; 
[dataMapping mapKeyPath:@"dog" toAttribute:@"dogs"]; 
[dataMapping mapKeyPath:@"person" toRelationship:@"person" withMapping:userMapping]; 
[[RKObjectManager sharedManager].mappingProvider addObjectMapping:dataMapping]; 

[[RKObjectManager sharedManager].mappingProvider setMapping:userMapping 
forKeyPath:@"people"];

RKObjectRouter * router = [RKObjectManager sharedManager].router;
[router routeClass: [Person class] toResourcePath:@"/people/:personId"];
[router routeClass: [Person class] toResourcePath:@"/people" 
forMethod:RKRequestMethodPOST];

RKObjectMapping *personSerializationMapping= [RKObjectMapping mappingForClass:
[NSMutableDictionary class]];
[personSerializationMapping mapAttributes:@"name", nil];
[[RKObjectManager sharedManager].mappingProvider 
setSerializationMapping:personSerializationMapping forClass: [Person class]];

Person* daveLiu =[[[Person alloc]init]autorelease];
daveLiu.name = @"dave";
[[RKObjectManager sharedManager] postObject:daveLiu  delegate:self];

我的服务器中的所有对象都是“匿名的”，而RestKit也无法找到正确的映射。我修复它的方法是使用objectManager方法，让我包含映射：

[objectManager postObject:object mapResponseWith:[object objectMapping] delegate:self];
[objectManager loadObjectsAtResourcePath:path objectMapping:mapping delegate:self];

所以现在我的合同都来自服务器这样：

{
    "Id": "12345678-1234-1234-1234-1234567890ab",
    "Type": "SURVEY",
    "Code": "1234",
    "Description": "blah blah blah",
    "Message": "blah blah blah",
    "Url": "http://nowhere.com/",
    "NextAttemptHours": 4
}

可以映射到正确的对象。保持对象映射可用是一项额外的工作，但它可以完成任务。我是通过在我的对象上实现一个类方法来返回适当的objectMapping来实现的，它使事情变得非常干净和易懂。

RESTkit代码1001找不到keyPath的对象：“'”
