There are many different solutions to this problem and there is no "right" way to do it. A few popular options are:
这个问题有很多不同的解决方案，没有“正确”的方法来解决这个问题。一些流行的选项是：
Core Data - Apple's framework for persistence. Very performant, but more difficult. SQLite - Fast and flexible, but bare bones. Plists - Basically writing a file to disk, you have to read and write manually. NSUserDefaults - The lightest weight "key-value" option. I would encourage you to read up on all four and see which one works best for you.
Core Data - Apple 的持久性框架。性能非常好，但更难。SQLite - 快速而灵活，但只是骨架。Plists - 基本上是将文件写入磁盘，您必须手动读取和写入。NSUserDefaults - 最轻量级的“键值”选项。我鼓励你阅读所有四个，看看哪一个最适合你。
