PayPal iOS SDK中的多个项目或多个数量

if (!payment.processable) {
    // This particular payment will always be processable. If, for
    // example, the amount was negative or the shortDescription was

有没有人有过使用PayPal iOS SDK的经验

现在我正在尝试将多个产品添加到一个总价格中。我已经看到，这在以后的iOS SDK中是不允许的。有人知道这是否已更新为允许此操作吗

如果没有。是否可能有一个单独的产品，但允许价格乘以数量

因此，在这个应用程序中，你需要选择一个医用手套，然后选择一个尺寸，然后选择一个数量。然后需要计算总数

这里是github上项目的链接

任何帮助或建议，我可以得到这项工作将不胜感激。谢谢

@用户3014076，PayPal iOS SDK目前仅支持每次付款的单一总额。您需要在应用程序中进行加法和乘法运算，然后只向SDK提交最终结果。

感谢Dave的回复。我不确定您是否查看过GitHub文件，但我尝试过这样做。现在我不知道我是否走对了这条路。但我确实试过这个。添加了上述部分的一些代码。@user3014076快速浏览一下，我觉得这些代码基本正确。你遇到问题了吗？是的，payment.amount字符串对我来说是空白的。但是如果我使用普通字符串[NSDecimal Number inItWithString=@“5.69”]（我从头开始思考），那么5.69就会出现。因此，这就像不理解所有这些字符串/文本字段的计算一样。我想添加图像，但没有声誉。@user3014076我很乐意帮助解决涉及PayPal iOS SDK的问题。但听起来剩下的问题实际上涉及将

totalpricecomputed

对象（其类我不知道）转换为

NSDecimalNumber

。这是一个通用的Objective C问题，而不是PayPal iOS SDK问题。嘿，Dave，Noobish问你一个问题，你如何将新的“税”和“运费”应用到视图控制器？有在线教程可以帮忙吗？
