iOS 100积分等于1元 总积分确定情况下，时时判断两个输入框积分抵扣，显示多少积分抵掉多少钱

1._gongshi_textField 第一个输入框

2._cailiao_textfile  第二个输入框

3.gonshiStr   第一个输入框的内容

4.cailiaoStr  第一个输入框的内容

5.self.first_message_label第一个现实积分抵扣详情Label   例如：@"可用0易币抵扣0.00元"

6.self.second_message_label 第一个现实积分抵扣详情Label 例如：@"可用0易币抵扣0.00元";

7.self.original_price  显示原价Label

8.self.Actual_price    显示真实价格Label

9.self.Actual_string   获取真实价格字符串
