[NSString stringWithFormat:@"%@% off entire order.",self.discountPercentage.text]
Example output would hopefully be something like: 25% off entire order.
希望示例输出如下:整个订单可享受25%的折扣。
Instead I get some crazy output: 25377777777776ff entire order.
相反,我得到一些疯狂的输出:25377777777776ff整个订单。
Is there an escape character I need to use before the %?
