如何在Macbook的iPhone 6s Simulator上找到SQLite数据库？

Question

I am searching for my SQLLite DB in my Simulator.

Based on ActivityMonitor, I am able to get the folder path of my Application.

/Users/MyMacBook/Library/Developer/CoreSimulator/Devices/A4170C16-A10B-4B48-9C7B-2A310F68B35F/data/Containers/Bundle/Application/F6C6772C-021A-4B27-874D-071B402DDBCC/

Though i couldn't find the SQLite database. I work on VS 2015 Xamarin Project.

How should i find SQLite db on my Simulator ?

Answer 1

Find the location of sqlite file by using the code in your appDelegate in the `didFinishLaunchingWithOptions'

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    print(FileManager.default.urls(for: .documentDirectory, in: .userDomainMask))
}

Every time when running the app, your can find the location printed in the Xcode console.

I'm using application simMagnifier to view the SQLite file

By default , most SQLite libraries/frameworks will place the Sqlite file in the root of your .app .

When you establish your SQLite connection if you are supplying a path and a filename to your SQLite file, then follow that path.

Example using sqlite-net :

var db = new SQLiteConnection("StackOverflow.sqlite");

Location:

cd Library/Developer/CoreSimulator/Devices
find $PWD -name "StackOverflow.sqlite" -print

/Users/sushi/Library/Developer/CoreSimulator/Devices/1EB2B821-E86B-4E9A-9814-1BBEF8FF1AA1/data/Containers/Bundle/Application/11BE399A-F802-4410-8163-32F5A90EB2FF/SQLiteLocation.app/StackOverflow.sqlite

Example using Path.GetTempPath :

var db = new SQLiteConnection(Path.Combine(Path.GetTempPath(), "StackOverflow.sqlite"));

Location:

cd Library/Developer/CoreSimulator/Devices
find $PWD -name "StackOverflow.sqlite" -print

/Users/sushi/Library/Developer/CoreSimulator/Devices/1EB2B821-E86B-4E9A-9814-1BBEF8FF1AA1/data/Containers/Data/Application/EED6E9CE-7437-48DD-904D-5F9D5E8AC78F/tmp/StackOverflow.sqlite

I use to use SimPholders (but it's paid). I found this free open-source alternative called Open Sim . It lets you browse the directories of the apps on your simulator. It makes it super easy to locate the sqlite db in your Xamarin App and then you just need a sqlite viewer to open the actual database.
