You can use following code to get the database created at in Documents folder. Just pass a path in documents folder and the function will copy the sqlite database in Documents folder at the given path if required. You can then use this path to create and query database tables.

+ (NSString*) createDatabaseIfRequiredAtPath:(NSString*)databasePath {

    if (databasePath == nil)
       return nil;


   NSString *path = [NSString stringWithFormat:@"%@/%@", databasePath, kMainDBName];
   NSFileManager *fileManager = [NSFileManager defaultManager];
   NSError *error = nil;

   if ([fileManager fileExistsAtPath:path] == NO) 
   {
    // The writable database does not exist, so copy the default to the appropriate location.
      NSString *defaultDBPath = [[NSBundle mainBundle] pathForResource:kMainDBName
                                                              ofType:nil];
      BOOL success = [fileManager copyItemAtPath:defaultDBPath 
                                       toPath:path
                                        error:&error];
      if (!success)
      {
        NSCAssert1(0, @"Failed to create writable database file with message '%@'.", [  error localizedDescription]);
        return nil;
    }
}

return path;
