核心数据中有以下实体:<代码>Account和CreditCard/code>。 缩略语 可有多个<代码> 核证中心代码>。 每一<代码>creditCard/code>都有<代码>/编号>。 我如何加密<代码>编号
?
我知道,在没有核心数据的情况下,我可以使用关键链服务,但我可以共同使用吗? 我想使用核心数据而不是像<代码>NSUserDefaults这样的数据,是因为我想处理多个账户。 我用了钥匙链服务,因此,我不敢肯定,如果它好坏于多个账户。

您可将核心数据中的关键链条改成
你可以把你想要加密的属性改变为可变的类型,并创建自己的NSValue Transformer,在改造时加密 在要求进行逆向变转时,价值被称作是加密的。
