試圖使用chcsvparser將coredata寫入csv

我已經完成了以下操作，將提取的請求放入數組數組中，但現在我不知道需要從chcsvparser調用哪些方法將其寫入csv文件試圖使用chcsvparser將coredata寫入csv

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]; 
}
