问题描述

我正在尝试使用 SQLite 浏览器查看我的核心数据对象.我无法找到核心数据在哪里保存其 sql 文件.我查看了应用程序文档文件夹，但那里什么也没有.

I am trying to us SQLite Browsers to see my Core Data objects. I am not able to find where does the core data save its sql file. I looked into the app documents folder but there is nothing there.

你知道IOS 10(模拟器)中的核心数据在哪里保存它的SQLite文件吗?

Do you know where does the core data in IOS 10(simulator) save its SQLite files on?

推荐答案

我在 XCode 8 Swift 3 OS macOS Sierra 上测试过

I tested it on XCode 8 Swift 3 OS macOS Sierra

IOS 10

在你的 Appdelegate.swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    let urls = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
     print(urls[urls.count-1] as URL)

    return true
}

1.常量 .documentDirectory 表示我们正在寻找 Document 目录

1. The constant .documentDirectory says we are looking for Document directory

2.常量 .userDomainMask 将我们的搜索限制在应用程序的沙箱中.

2. The constant .userDomainMask to restrict our search to our application's sandbox.

输出

file:///Users/Ashok/Library/Developer/CoreSimulator/Devices/F629F99F-C745-46EB-8A11-01BC9FF1E592/data/Containers/Data/Application/3B373C93-71A2-46E9-8AF7-EF407C39429F/Documents/

点击 Go -> Go to Folder -> Paste Path -> 按 Enter

然后转到库 -> 应用程序支持 -> filename.sqlite

已编辑

或

打开你的终端并输入 find ~ -name 'HitTest.sqlite' 然后回车.

open your terminal and type find ~ -name 'HitTest.sqlite' and hit enter.

Ashoks-MacBook-Pro:Desktop Ashok$ find ~ -name 'HitTest.sqlite'
/Users/Ashok/Library/Developer/CoreSimulator/Devices/F629F99F-C745-46EB-8A11-01BC9FF1E592/data/Containers/Data/Application/3B373C93-71A2-46E9-8AF7-EF407C39429F/Documents/HitTest.sqlite

从上面的输出你可以清楚地看到你的sqlite db的路径

您可以使用 DB Browser for SQLite 打开.
