JsonMap

swift json对象和模型转换工具类

定义JsonMap实体类

class Person: JsonMap {
    @objc var name = ""
    @objc var age = 0

    override var description: String {
        return super.description + " name=" + name + " age=" + "\(age)"
    }
}

注意：JsonMap使用OC的runtime机制进行映射，在swift4.0需要指定哪些属性可以桥接到OC类，你只要在属性前添加@objc标识即可。

JsonMap的简单使用

字典转模型

let dict : [String : Any] = ["name":"jack", "age": 10]
if let person = Person.mapToObj(dict: dict) {
    print("--dict mapToObj--")
    print("dict = \(dict)")
    print(person)
}

数组转模型数组

let arr : [[String : Any]] = [["name":"tom", "age":19], ["name":"rose", "age": 17]]
if let persons = Person.mapToObjs(arr: arr) {
    print("--arr mapToObjs--")
    print("arr = \(arr)")
    print(persons)
}

模型转字典

let person = Person()
person.name = "myName"
person.age = 35
let keyValue = person.keyValues()
print("--keyValues--")
print(person)
print("keyValue = \(keyValue)")

字典赋值

let dict = ["name":"111", "age": 100]
let person = Person()
person.setMapValuesForKeys(dict)
print("--setMapValuesForKeys--")
print("dict = \(dict)")
print(person)

自定义映射

class CustomMapPerson: Person {
    override class func map(dict: Any?) -> [String:Any]? {
        if var dict = super.map(dict: dict) {
            if let name = dict["name"] as? String {
                dict["name"] = "my name is " + name
            }
            if let age = dict["age"] as? Int {
                dict["age"] = 10 + age
            }
            return dict
        }
        return nil
    }
}

let dict = ["name":"222", "age":5];
if let person = CustomMapPerson.mapToObj(dict: dict) {
    print("--CustomMapPerson--")
    print("dict = \(dict)")
    print(person)
}

自定义映射键

class MapKeysPerson: Person {
    override class var mapKeys: [String:String] {
        return ["name":"myName", "age":"myAge"]
    }
}

let dict = ["myName":"111", "myAge":48]
if let person = MapKeysPerson.mapToObj(dict: dict) {
    print("--map--MapKeysPerson--")
    print("dict = \(dict)")
    print(person)
    print()
    let keyValue = person.keyValues()
    print("--map--MapKeysPerson--keyValues--")
    print(person)
    print("keyValue = \(keyValue)")
}

let dict = ["name":"111", "age":48]
if let person = MapKeysPerson.mapToObj(dict: dict) {
    print("--not map--MapKeysPerson--")
    print("dict = \(dict)")
    print(person)
    print()
    let keyValue = person.keyValues()
    print("--not map--MapKeysPerson--keyValues--")
    print(person)
    print("keyValue = \(keyValue)")
}

黑名单

class BlacklistPerson: Person {
    override var blacklist: [String] {
        return ["age"]
    }
}

let dict = ["name":"333", "age":90]
if let person = BlacklistPerson.mapToObj(dict: dict) {
    print("--BlacklistPerson--")
    print("dict = \(dict)")
    print(person)
}

白名单

class WhitelistPerson: Person {
    override var whitelist: [String] {
        return ["age"]
    }
}

let dict = ["name":"888", "age":467]
if let person = WhitelistPerson.mapToObj(dict: dict) {
    print("--WhitelistPerson--")
    print("dict = \(dict)")
    print(person)
}

模型数组属性

class House: JsonMap {
    @objc var address = ""
    @objc var area = 0
    override var description: String {
        return super.description + " address=" + address + " area=" + "\(area)"
    }
}

class ArrayHousePerson: Person {
    @objc var houses: [House] = []
    override var arrClasses: [String : AnyClass] {
        return ["houses":House.classForCoder()]
    }
    override var description: String {
        return super.description + " houses=" + "\(houses)"
    }
}

let arr = [["address":"xxx", "area":100], ["address":"yyy", "area":200]]
let dict = ["name":"ming", "age":13, "houses":arr]
if let person = ArrayHousePerson.mapToObj(dict: dict) {
    print("--ArrayHousePerson--")
    print("dict = \(dict)")
    print(person)
}

简单数组属性

class ArrayPerson: Person {
    @objc var numbers: [Int] = []
    override var description: String {
        return super.description + " numbers=" + "\(numbers)"
    }
}

let dict = ["name":"ling", "age":11, "numbers":[1,2,3]]
if let person = ArrayPerson.mapToObj(dict: dict) {
    print("--ArrayPerson--")
    print("dict = \(dict)")
    print(person)
}

模型属性

class House: JsonMap {
    @objc var address = ""
    @objc var area = 0
    override var description: String {
        return super.description + " address=" + address + " area=" + "\(area)"
    }
}

class HousePerson: Person {
    @objc var house: House?
    override var description: String {
        return super.description + " house=" + String.init(describing: house)
    }
}

let dict = ["name":"ying", "age":19, "house":["address":"nnb", "area":170]]
if let person = HousePerson.mapToObj(dict: dict) {
    print("--HousePerson--")
    print("dict = \(dict)")
    print(person)
}

简单字典属性

class DictionaryPerson: Person {
    @objc var info: [String:Any] = [:]
    override var description: String {
        return super.description + " info=" + "\(info)"
    }
}

let dict = ["name":"ping", "age":27, "info":["string":"bbbb", "double":19.7]]
if let person = DictionaryPerson.mapToObj(dict: dict) {
    print("--DictionaryPerson--")
    print("dict = \(dict)")
    print(person)
}
