Viewing SQLite3 Database (XCODE)

问题:

I am creating an iphone app within XCODE the makes use of an SQLite3 database. I am creating the database programmatically if it does not exist. I am not getting any errors when I run the program.

How can I check the contents of the database to ensure that the data has been inserted correctly into the correct columns? Where does Xcode place the table within my system where I can view it?

回答1:

The SQLite database will be created in your apps Documents folder, in the simulator's base directory.

Before Xcode 6, you can check in:

~/Library/Application Support/iPhone Simulator/4.2/Applications/GUID/Documents

There is also a Mac OS X application called SQLiteBrowser that you can use to browse the database your app created.

Update :

As of Xcode 6, the new iOS simulator's directory is located here :

~/Library/Developer/CoreSimulator

Ultimately, you can find your app's database under a location like this (Replace UIDs by yours) : ~/Library/Developer/CoreSimulator/Devices/4D2D127A-7103-41B2-872B-2DB891B978A2/data/Containers/Data/Application/0323215C-2B91-47F7-BE81-EB24B4DA7339/Documents/MyApp.sqlite

If you want to view the database that you are created,

Open finder press Command+g "~/Library/Application Support/iPhone Simulator" then go.

Open 5.0 (as per your version of simulator)-> Application-> select the pgm folder

-> Documents

Then you can see the database

There are a bunch of standalone programs that look at sqllite files. A very popular one for the Mac is called "Base":

The simulator directory has been moved with Xcode 6 to: ~/Library/Developer/CoreSimulator. To find the unique path add the following statement to the AppDelegate.m file, applicationDocumentsDirectory method:

NSLog(@"%@",[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]);

Xcode 9.1:

1. Open Terminal, type:

   cd ~ & find -name "YourModelName.sqlite"

2. You'll most likely be presented with such a path:

~/Library/Developer/CoreSimulator/Devices/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/data/Containers/Data/Application/YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY/Library/Application Support/

3. Open Finder, press Shift + Command + G, paste the path and press Go.
4. Use DB Browser for SQLite to view the .sqlite file.
