Objectmapper: Alternative keys for the same property

[wassimseif]

Your JSON dictionary:

{
    "user_name" : "John Doe"
}

```json
{
"userName" : "John Doe"
}

### Your model:

```swift
class User :  Mappable{

    var userName : String?

    func mapping(map: Map)
    {
        userName <- map["userName"]

    }
}

Is there any way to let ObjectMapper support multiple keys for the same property in the Model ?
This is a good way to support APIs from different enviroments

ObjectMapper does not provide a mechanism for handling this situation. You can easily check if a value was successfully mapped in the mapping function though.

userName <- map["userName"]
if userName == nil {
    username <- map["user_name"]
}
