1.只包含一个模型类的字典解析
func JsonNormalModel() -> () {
let jsonDic = ["userName":"beer", "age":"100","userEmail":"yaozuopan@icloud.com"] as [String : Any]
let jsonData = try! JSONSerialization.data(withJSONObject: jsonDic, options: .prettyPrinted)
let decode = JSONDecoder()
if let user = try? decode.decode(Usre.self, from: jsonData){ print(user.userEmail)}
}
2.模型数组的字典解析
func JsonArrModel(complition:@escaping (_ list:[Usre])->()) -> () {
let mainDic = ["name":"软件部","id":"888","member":[["userName":"beer0", "age":"101","userEmail":"yaozuopan4@icloud.com"],["userName":"beer1", "age":"103","userEmail":"yaozuopan3@icloud.com"]]] as [String : Any]
let mainData = try! JSONSerialization.data(withJSONObject: mainDic, options: .prettyPrinted)
let decode1 = JSONDecoder()
if let group = try? decode1.decode(Department.self, from: mainData)
{ var arrayM = [Usre]()
for (indexs,item) in group.member.enumerated() {
print("索引:\(indexs) 值:\(item)")
arrayM.append(item)
}
complition(arrayM)
} }
3. viewDidLoad回调函数
var listArr = [Usre]()
override func viewDidLoad() {
super.viewDidLoad()
JsonArrModel { (List) in
self.listArr += List
}
let user = self.listArr[0]
print("\(user.userName) \(user.userEmail) \(user.age)")
}
4.模型类
class Usre: Codable {
var userName:String
var age:String
var userEmail:String
init(userName:String,age:String,userEmail:String) {
self.userEmail = userEmail
self.userName = userName
self.age = age}
}
class Department: Codable {
var name: String
var id: String
var member: [Usre
init(name: String, id: String ,member:[Usre]) {
self.name = name;
self.id = id;
self.member = member;
}
}
