我正在尝试使用JSON数据执行POST请求到我的API：
我的班级实施：
class Person: NSObject {
var theId: String?
var countrycode: Int?
var language: String?
}
app委托类中的映射和描述符：
let requestMapping = RKObjectMapping.request()
requestMapping?.addAttributeMappings(from: ["theId":"theId", "countrycode":"countrycode", "language":"language"])
let requestDescriptor = RKRequestDescriptor(mapping: requestMapping, objectClass: Person.self, rootKeyPath: nil, method: .any)
objectManager.addRequestDescriptor(requestDescriptor)
我在以下代码中使用它：
self.objectManager.post(person, path: "my_path", parameters: nil, success: { (operation, result) in
// OK Response Here
}) { (operation, error) in
// Error Response Here
}
我的API预期JSON：
{
"theId":"123",
"countrycode":1001,
"language":"en"
}
但是，我的所有映射值都设置为null。但是在调试器中，我的对象值被设置为正确的值，我在使用对象之前确认了。
这是我的日志：

RestKit使用键/值编码从对象中提取属性。这意味着必须将Swift对象中的属性声明为@objc，并为RestKit声明dynamic以发现它们。
