一、系统自带的KVC
模型：
import UIKit
class BaseModel: NSObject {
init(dict: [String: AnyObject]) {
super.init()
//setValuesForKeys是KVC方法
//KVC的方法又是OC的方法，在运行时给对象发送消息，这点要求对象已经实例化完成。super.init()就是用来保证对象初始化完成。
setValuesForKeys(dict)
}
//重写父类的方法
override func setValue(_ value: Any?, forUndefinedKey key: String) {
//没有调用super，将父类的代码完全覆盖，不会崩溃
}
}
class TypesSATMD: BaseModel {
var msg: String = ""
var ret: Int = 0
var data: [String: NSObject]? {
didSet {
guard let tempData = data else { return }
typesSATData = TypesSATData(dict: tempData)
}
}
var typesSATData: TypesSATData?
}
class TypesSATData: BaseModel {
var cate: [[String: NSObject]]? {
didSet {
guard let tempCate_list = cate else { return }
for dict in tempCate_list {
cates.append(TypesSATCate(dict: dict))
}
}
}
var pic: [[String: NSObject]]? {
didSet {
guard let banner_list = pic else { return }
for dict in banner_list {
pics.append(TypesSATPic(dict: dict))
}
}
}
var cates: [TypesSATCate] = [TypesSATCate]()
var pics:[TypesSATPic] = [TypesSATPic]() // 轮播图数组
}
class TypesSATCate: BaseModel {
var grade: Int = 0
var id: NSNumber = NSNumber()
var name: String = ""
var parId: String = ""
var picUrl: String = ""
var subList: [[String: NSObject]]? {
didSet {
guard let tempSubList = subList else { return }
for dict in tempSubList {
subLists.append(TypesSATSubList(dict: dict))
}
}
}
var subLists: [TypesSATSubList] = [TypesSATSubList]()
}
class TypesSATPic: BaseModel {
var link: String = ""
var picUrl: String = ""
var price: Double = 0
var prodId: NSNumber = NSNumber()
var storeId: NSNumber = NSNumber()
var text1: String = ""
var text2: String = ""
var type: Int = 0
}
class TypesSATSubList: BaseModel {
var grade: Int = 0
var id: NSNumber = NSNumber()
var name: String = ""
var parId: NSNumber = NSNumber()
var picUrl: String = ""
}
使用 eg：
let type: TypesSATMD = TypesSATMD(dict: (result as? [String : NSObject])!)
print(type.typesSATData?.pics.first?.picUrl ?? "")
二、SwiftyJSON
源码：https://github.com/SwiftyJSON/SwiftyJSON.git
初始化：
let json = JSON(data: dataFromNetworking)
let json = JSON(jsonobject)
if let dataFromString = jsonString.data(using: .utf8, allowLossyConversion: false) {
let json = JSON(data: dataFromString)
}
一些常用的方法：
//从 JSON数组 中获取一个 double
let name = json[0].double
//用来显示 JSON 中是否有指定的值
if json["name"].exist()
三、ObjectMapper
源码：https://github.com/Hearst-DD/ObjectMapper.git
导入头文件：import ObjectMapper
模型继承：Mappable
实现两个协议方法：
required init?(map: Map){
}
func mapping(map: Map) {
}
模型：
import UIKit
import ObjectMapper
class TypeMD: Mappable {
var ret: Int = 0
var data: TypeData?
var msg: String = ""
required init?(map: Map){
}
func mapping(map: Map) {
ret <- map["ret"]
data <- map["data"]
msg <- map["msg"]
}
}
class TypeData: Mappable {
var pic: [TypePic] = [TypePic]()
var cate: [TypeCate] = [TypeCate]()
required init?(map: Map){
}
func mapping(map: Map) {
pic <- map["pic"]
cate <- map["cate"]
}
}
class TypePic: Mappable {
var picUrl: String = ""
var prodId: Int = 0
var text1: String = ""
var price: Int = 0
var text2: String = ""
var storeId: Int = 0
var link: String = ""
var type: Int = 0
required init?(map: Map){
}
func mapping(map: Map) {
picUrl <- map["picUrl"]
}
}
class TypeCate: Mappable {
var picUrl: String = ""
var id: Int = 0
var subList: [TypeSublist] = [TypeSublist]()
var grade: Int = 0
var name: String = ""
var parId: String = ""
required init?(map: Map){
}
func mapping(map: Map) {
name <- map["name"]
}
}
class TypeSublist: Mappable {
var parId: Int = 0
var id: Int = 0
var grade: Int = 0
var name: String = ""
var picUrl: String = ""
required init?(map: Map){
}
func mapping(map: Map) {
name <- map["name"]
}
}
使用eg:
let test1 = Mapper<TypeMD>().map(JSONObject: result)
print(test1?.data?.cate.first?.name ?? "")
