Swift 解档和归档

概述1.对用户的模型数据(自定义类:HCUserModel)进行归档和解档 1.1 需要遵循NSCoding协议 1.2 需要实现func encode(with aCoder: NSCoder){}归档方法 1.3需要实现 required init(coder aDecoder: NSCoder){}解档方法 import UIKitclass YMUserAccount:NSObject,N

1.对用户的模型数据(自定义类:HCusermodel)进行归档和解档

1.1 需要遵循NSCoding协议

1.2 需要实现funcencode(with aCoder:NSCoder){}归档方法

1.3需要实现requiredinit(coder aDecoder:NSCoder){}解档方法

import UIKitclass YMUserAccount:NSObject,NSCoding {    //MARK:-属性    //授权Acccesstoken    var access_token:String?    //过期时间-->秒    var expires_in:TimeInterval=0.0{                dIDSet{                        expires_date=Date(timeIntervalSinceNow: expires_in)            }            }    //用户ID    var uID :String?                //昵称     var screen_name:String?    var avatar_large:String?            //额外参数    var expires_date:Date?        //MARK:-自定义构造函数    init(dic:[String:AnyObject])    {        super.init()            access_token=dic["access_token"] as! String?        uID=dic["uID"] as! String?        expires_in=dic["expires_in"] as! TimeInterval                        }    overrIDe func setValuesForKeys(_ keyedValues: [String : Any]) {            }            //MARK:-解档 归档    //解档的方法           required init?(coder aDecoder: NSCoder) {                super.init()                access_token=aDecoder.decodeObject(forKey: "access_token") as! String?        uID=aDecoder.decodeObject(forKey: "uID") as! String?        expires_date=aDecoder.decodeObject(forKey: "expires_date") as! Date?        screen_name=aDecoder.decodeObject(forKey: "screen_name") as! String?        avatar_large=aDecoder.decodeObject(forKey: "avatar_large") as! String?                    }    //归档的方法    func encode(with aCoder: NSCoder) {                aCoder.encode(access_token,forKey: "access_token")        aCoder.encode(uID,forKey: "uID")        aCoder.encode(expires_date,forKey: "expires_date")        aCoder.encode(screen_name,forKey: "screen_name")        aCoder.encode(avatar_large,forKey: "avatar_large")    }}

将account对象保存到本地                          //获取沙盒路径            var accountPath=NSSearchPathForDirectorIEsInDomains(.documentDirectory,.userDomainMask,true).first!             accountPath+="/userAccount.pList"            print("路径："+accountPath);            NSKeyedArchiver.archiveRootObject(account,tofile: accountPath)

//从沙盒中读取归档的信息                var accountPath=NSSearchPathForDirectorIEsInDomains(.documentDirectory,true).first!        accountPath+="/userAccount.pList"        let account=NSKeyedUnarchiver.unarchiveObject(withfile: accountPath) as? YMUserAccount
