如何从iPhone应用程序访问Xcode数据库

Question

This is my first iPhone app. I'm using Xcode 7.3.

In the app I used this tutorial to create an sql database using the app (when the user gives permission by pressing a button, it creates the .db file).

Now I would like to know how I can download the database from the app.

Here is why:

The app will be downloaded on someone's device (not via the app store). It is supposed to collect data from a wearable device and store it in the database.

However I don't know how to access that data later on when I have the user's phone. Apparently the db lives in

/var/mobile/Containers/Data/Application/###/Documents

I read that one method is "jailbreaking." But I have never done that and this is not my phone I'm dealing with, it's a client's, so I don't feel comfortable hacking it. Is there another way? Possibly through the terminal (this is how I did it with the android app, using adb)?

Or is there another way I can go about saving the database so that it is accessible/retrievable?

Answer 1

The first answer is correct but incomplete :

Once you have download the Container, the extension is .xcappdata, so you need to right-click on it and select show the package.

Then browse into /library/Application support/ to find your database in .sqlite

Answer 2

You can try to connect the device to your Mac, then in XCode, go to Window, Devices, select your device and app bundle and click "Download Container...".

To see the database, you could use SQLite .
