1.在class OAuthViewController:UIViewController
// 3.从字典中取出昵称和用户头像地址(account :UserAccount)
account.screen_name = userInfoDict["screen_name"]as?String
account.avatar_large = userInfoDict["avatar_large"]as?String
// 4.将account对象保存
NSKeyedArchiver.archiveRootObject(account, toFile: UserAccountViewModel.shareIntance.accountPath)
2.在class UserAccount:NSObject,NSCoding
// MARK:-归档&解档
///解档的方法
requiredinit?(coder aDecoder:NSCoder) {
access_token= aDecoder.decodeObjectForKey("access_token")as?String
uid= aDecoder.decodeObjectForKey("uid")as?String
expires_date= aDecoder.decodeObjectForKey("expires_date")as?NSDate
avatar_large= aDecoder.decodeObjectForKey("avatar_large")as?String
screen_name= aDecoder.decodeObjectForKey("screen_name")as?String
}
///归档方法
funcencodeWithCoder(aCoder:NSCoder) {
aCoder.encodeObject(access_token, forKey:"access_token")
aCoder.encodeObject(uid, forKey:"uid")
aCoder.encodeObject(expires_date, forKey:"expires_date")
aCoder.encodeObject(avatar_large, forKey:"avatar_large")
aCoder.encodeObject(screen_name, forKey:"screen_name")
}
3.在其它类中提取沙河里的值
// 1.从沙盒中读取中归档的信息
var accountPath =NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask,true).first!
accountPath = (accountPath as NSString).stringByAppendingPathComponent("account.plist")
account=NSKeyedUnarchiver.unarchiveObjectWithFile(accountPath) as? UserAccount
//取出值,如下
account.screen_name
