Trying to write coredata to csv using chcsvparser

I've done the following to put a fetched request into an array of arrays but now i don't know which methods i need to call from chcsvparser to write this into a csv file

NSArray *objectsForExport = [fetchedResultsController fetchedObjects];
NSArray *exportKeys = [NSArray arrayWithObjects:@"best_checkout", @"darts_thrown", @"high_score", @"score_100", @"score_140", @"score_180",@"three_dart_average",nil];

NSMutableArray *csvObjects = [NSMutableArray arrayWithCapacity:[objectsForExport count]];
for (NSManagedObject *object in objectsForExport) {
    NSMutableArray *anObjectArray = [NSMutableArray arrayWithCapacity:[exportKeys count]];
    for (NSString *key in exportKeys) {
        id value = [object valueForKey:key];
        if (!value) {
            value = @"";
        }
        [anObjectArray addObject:[value description]];
    }
    [csvObjects addObject:anObjectArray];
}

As Johann suggests, you should use the writeToCSVFile:atomically: convenience method. However, be aware that using it as you describe in your comment is not correct.

The NSString you pass in should be the filepath you want the data writing to.
