Auto Reflection

1. set up a Model:

class People: JSONNDModel {
    @objc var name = ""
}

2. reflex JSON to Model automatic:

let json = JSONND(dictionary: ["name": "JohnLui"])
let people = People(JSONNDObject: json)

print(people.name) // get "JohnLui"

3. custom mapping

class Good : JSONNDModel {
    @objc var des = ""
    required init(JSONNDObject json: JSONND) {
        super.init(JSONNDObject: json)
        self.des = json["description"].stringValue
    }
}

4. something you need to know

auto reflection from JSON to Model need every variable in JSONNDModel class has a default value:

class People: JSONNDModel {
    @objc var name = ""
    @objc var number = 0
    @objc var array = [Int]()
}

multi-level reflection need a init in init() function:

class TestModel: JSONNDModel {
    @objc var string = ""
    @objc var double = 0.0
    @objc var int = 0
    @objc var array_values = [Int]()
    @objc var array = [ModelOnlyOneKey]()
    @objc var hey: Hey!
    required init(JSONNDObject json: JSONND) {
        super.init(JSONNDObject: json)
        
        for i in json["array_values"].arrayValue {
            self.array_values.append(i.intValue)
        }
        for i in json["array"].arrayValue {
            self.array.append(ModelOnlyOneKey(JSONNDObject: i))
        }
        self.hey = Hey(JSONNDObject: json["hey"])
    }
}
class ModelOnlyOneKey: JSONNDModel {
    @objc var key = 0
}
class Hey: JSONNDModel {
    @objc var man: Man!
    required init(JSONNDObject json: JSONND) {
        super.init(JSONNDObject: json)
        
        self.man = Man(JSONNDObject: json["man"])
    }
}
class Man: JSONNDModel {
    @objc var hello = false
}
