//    需要用到开源类SSKeychain
//    SSKeyChains对苹果安全框架API进行了简单封装，
//    支持对存储在钥匙串中密码、账户进行访问，包括读取、删除和设置。
//    SSKeyChain的作者是大名鼎鼎的SSToolkit的作者samsoffes。
    
//    项目地址：https://github.com/samsoffes/sskeychain
    
//    在工程中加入SSKeyChain
    
//    在工程中加入Security.framework框架。
//    把SSKeychain.h和SSKeychain.m加到项目文件夹。
