iOS上的Objective C数据缓存 [英] Objective C Data Caching on iOS

问题描述

我从API中提取数据，然后使用它来构建我的数据对象。我想缓存此数据为未来。我一直存储从api在NSUserDefaults的字符串，然后重新解析它每次应用程序加载。这工作，但它真的似乎是错误的方式去。

I am pulling data from an API and then building out my data objects with it. I want to cache this data for the future. I have been storing the string from the api in NSUserDefaults and then re-parsing it each time the app loads. This works, but it really seems like the wrong way to go about it.

如何做到这一点？

推荐答案

这个问题的解决方案，没有正确的方式做到这一点。以下几个热门选项是：

There are many different solutions to this problem and there is no "right" way to do it. A few popular options are:

• 收集数据 - 苹果的持久性框架。非常高效，但更困难。


• SQLite - 快速，灵活，但只是骨骼。


• Plists - 基本上将文件写入磁盘，必须手动读写。


• NSUserDefaults - 最轻的键值选项。

• 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.

我鼓励你阅读所有四个，看看哪一个最适合你。

I would encourage you to read up on all four and see which one works best for you.
