在 Swift 中覆盖 Objective-C 类方法

Question

I'm trying to use JSONModel in a Swift project. I would like to override the method keyMapper from JSONModel but I don't find how to override an Objective-C class method in the model class.

The signature of the method is:

+(JSONKeyMapper*)keyMapper;

How can I do that?

Answer 1

You do it just like you override an instance method, except with the class keyword:

override class func keyMapper() -> JSONKeyMapper! {
    //code here
}
