建议在哪里存储iOS应用程序的数据 [英] Advise where to store data for iOS app

问题描述

我使用ionic和cordova创建了一个应用程序，现在我想在iOS上重新制作它。我是第一次使用iOS，我无法弄清楚如何存储数据。
例如：我有一个表单，用户必须输入一些数据，但输入不在一个视图中，必须有几个视图。我曾经创建空数组，只是一步一步地放置所有内容，但现在我不能在多个视图上使用相同的视图控制器。试图用核心数据来做，但核心数据不能存储数组。我的对象看起来像这样：

I have created an app using ionic and cordova and now I want to remake it on iOS. I am working with iOS for the first time, and I cannot figure out how to store data. For example: I have a form where user has to input some data, but the inputs are not in one view, there must be several views. I used to create empty array and just put everything step by step, but now i can't use same view controller on multiple views. Tried to do it with core data, but core data cannot store arrays. My object would look something like this:

var sampleArray = (
duration: 13,
dayOfTheWeek: Thursday,
personList: [
  (name: Rocky,
   age: 26),
  (name: Ralph,
   age:23)
  ]
)

问题是：我如何制作一个输入表格，视图和我应该在哪里存储数据，以后我可以将所有数据存储到核心数据中？

The question would be: How could I make an input form which would be on several views and where should I store the data, and later I would be able to store all the data into core data?

推荐答案

As第一条评论说，你的问题非常大。
当你说'几个视图中的一个表单'时，我认为它是'每个视图的一个表单'。
保持简单S ...;）
（除非您对表单使用页面控制。）

As the first comment says, your question is quite large. When you say 'one form on several view', I consider it as 'one form per view'. Keep It Simple S... ;) (Except if you use page control for your form.)

基本上，您有三种方式存储数据：

Basically, you have three ways to store data :

• NSUserDefaults：
  将数据存储在字典中供以后使用


• 文件：
  将数据保存到文件中（为什么不.csv之类的？）


• CoreData：
  您可以将数组作为二进制数据保存在Core Data中
