Question

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];
}
