PayPal iOS SDK 上的多个项目或多个数量

Question

**针对运费/税务帮助更新**

NSDecimalNumber *totalPriceNumber = [NSDecimalNumber decimalNumberWithDecimal:[@(totalAmount) decimalValue]];
NSDecimalNumber *taxAmount = [NSDecimalNumber decimalNumberWithString:@"0.07"];
NSDecimalNumber *shippingAmount = [NSDecimalNumber decimalNumberWithString:@"20.00"];
NSDecimalNumber *subtotalAmount = [NSDecimalNumber decimalNumberWithString:@"5.00"];


NSString *productFirst = [hiddenGloveIDOne text];
NSString *productSecond = [hiddenGloveIDTwo text];
NSString *productThird = [hiddenGloveIDThree text];
NSString *productFourth = [hiddenGloveIDFour text];

NSString *productCheckOut = [NSString stringWithFormat:@"%@%@%@%@", productFirst, productSecond, productThird, productFourth];

self.resultText = nil;

PayPalPayment *payment = [[PayPalPayment alloc] init];
payment.paymentDetails = [[PayPalPaymentDetails alloc] init];

payment.amount = totalPriceNumber;
payment.currencyCode = @"USD";
payment.shortDescription = productCheckOut;
payment.paymentDetails.subtotal = subtotalAmount;
payment.paymentDetails.shipping = shippingAmount;
payment.paymentDetails.tax = taxAmount;

有人对 PayPal iOS SDK 资源有任何经验吗？

现在我正在尝试将多个产品添加到总价格中。我已经看到这在后来的 iOS SDK 中是不允许的。有人知道这是否已更新为允许这样做吗？

如果没有。是否有可能拥有一种单独的产品，但允许价格乘以数量？

所以在这个应用程序中发生的事情是您选择一个医用手套 - 然后是尺寸 - 然后是数量。然后需要计算总数。

如果我能得到这项工作的任何帮助或建议，我将不胜感激。谢谢！

NSString *result = [NSString stringWithFormat:@" $ %0.2f", totalAmount];

[totalPriceCalculated setText:result];

// Remove our last completed payment, just for demo purposes.
self.completedPayment = nil;

PayPalPayment *payment = [[PayPalPayment alloc] init];
payment.amount = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:@"%@", totalPriceCalculated.text]];
payment.currencyCode = @"USD";
payment.shortDescription = @"Hipster t-shirt";

if (!payment.processable) {
    // This particular payment will always be processable. If, for
    // example, the amount was negative or the shortDescription was
    // empty, this payment wouldn't be processable, and you'd want
    // to handle that here.
}

@user3014076，PayPal iOS SDK 目前仅支持每次付款的单个总金额。您需要在应用中进行加法和乘法运算，然后仅将最终结果提交给 SDK。
