So I got SQLite database working for my app. It loads text values from database, copies it to the array and displays it in Table View.

The first time I got it going i had the values Tuesday, Thursday, Saturday displaying. Then I modified the database using SQLite Manager add-on for firefox (I also used it to create it) by adding new values. However, the new values are not displaying, and even if I delete values like Saturday, the same old “Tuesday, Thursday, Saturday” keeps reappearing. I’m baffled.

Notes:

  • I tried restarting Xcode and even the computer lol.
  • When I modify database in SQLite Manager, the update time on database file is refreshed in Xcode.
  • My database management, just like in the tutorial, happens in AppDelegate.

  • In appdelegate: (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions I have this code at beginning

    routines = nil; // Reset array
database = nil; // not opened yet
selStmt = nil; // no compiled statement yet
updStmt = nil; // no compiled statement yet

I’m following this tutorial and modifying it on my needs:

    You’re probably copying the database from the app bundle into the documents directory if it doesn’t already exist in the documents directory.

    The next time you run your app (with a new db) you check that the db exists in the user’s documents directory and then you’re probably not copying it again. You’re not comparing the versions of the db, you’re just checking that a db with that name exists.

    If you’re in development still, an easy solution is to just clear reset the content and settings of the simulator, which will cause your app to copy the db again.
