这个文档模板中的星星是什么意思？

我正在尝试在数组中打印几个对象的名称.它们都是名为StockHolding的类的实例化,并命名为stock1,stock2和stock3.但我无法弄清楚如何让NSLog打印这些实例的实际名称.相反,它打印出实例所属类的名称和内存地址(例如,"2013-12-12 21:06:05.782股票[18093:303]股票价值2.30,当你买它.它现在价值4.50你有40股.").我希望它打印"Stock stock1值得......"如何让NSLog打印出阵列中实例的名称？以下代码段:

    NSMutableArray *myStocks = [[NSMutableArray alloc] init];

    [myStocks addObject:stock1];
    [myStocks addObject:stock2];
    [myStocks addObject:stock3];
    for (StockHolding *s in myStocks) {
        NSLog(@"Stock %@ was worth %.02f when you bought it. It's now worth %.02f. You have %d shares of it.", s, s.purchaseSharePrice, s.currentSharePrice, s.numberOfShares);
    }
