Answer 1

+(DataManager*)getSharedInstance{
if (!sharedInstance) {
    sharedInstance = [[super allocWithZone:NULL]init];
    [sharedInstance copyDatabaseIntoDocumentsDirectory];
}
return sharedInstance;

}

-(void)copyDatabaseIntoDocumentsDirectory{

// Set the documents directory path to the documentsDirectory property.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
self.documentsDirectory = [paths objectAtIndex:0];

// Keep the database filename.
self.databaseFilename = DATABASE_FILENAME;

// Check if the database file exists in the documents directory.
destinationPath = [self.documentsDirectory stringByAppendingPathComponent:self.databaseFilename];

if (![[NSFileManager defaultManager] fileExistsAtPath:destinationPath]) {
    // The database file does not exist in the documents directory, so copy it from the main bundle now.
    NSString *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:self.databaseFilename];
    NSError *error;
    [[NSFileManager defaultManager] copyItemAtPath:sourcePath toPath:destinationPath error:&error];

    // Check if any error occurred during copying and display it.
    if (error != nil) {
        NSLog(@"%@", [error localizedDescription]);
    }
}

}

Note : error 260 : meaning the file could not be found at the path you specified (once again create DB and then add your project).
