例如

6个仓库的开关

我应该在学习数据库存储吗?我可以将数据保存到手机吗?

Should I be looking at learning database storage? Can I save data to the phone?

推荐答案

如果要存储的数据很少且不敏感，则可以使用UserDefaults 例如，用户名，年龄等.

If the data you want to store is very little and not sensitive, you can use UserDefaults For example, user's name, their age etc.

对于大量数据，您应该使用Core Data，它是一种管理对象的好方法.例如，您有1000个项目，每个项目都有一个属性，基本上可以使用核心数据.这非常简单，例如如何创建托管对象，存储它们以及以后如何使用查询检索它们.

For Large amounts of data you should use Core Data, its a good and an easy way to manage your objects. For example, you have 1000 items, each with a property, you can basically use core data for that. It is pretty straightforward as how to create Managed Objects, store them and how to later retrieve them using queries.

基本上，当您使用核心数据配置项目时，项目会创建一个附加到项目的sqlite文件.

Basically when you configure your project with core data, project creates an sqlite file attached to your project.

关于如何开始使用Core Data的教程很多，如果您对iOS有一般的经验，那对您来说简直是小菜一碟.
