2 // 1.保存方式:创建一个纯文本文件,或是使用更规范的格式(如XML)来保存
3 // 2.在数据库中保存首选项
4 // 3.使用USUserDefault
5 //
6 // USUserInfo常见方法:
7 // 1.standardUserDefaults 创建共享默认对象方法
8 // 2.objectForKey 返回键的实例方法。保存在许多变体，可以返回特定对象类型,比如字符串、布尔值等
9 // 3.setobjectForKey 设置对象值的实例方法。保存在许多变体，可以返回特定对象类型,比如字符串、布尔值等
10 // 4.objectForKey 保存共享类对象发生的所有更改的类方法
