我在 iOS 9.0 中打开 Paypal 时出错，但它在 ios 7 和 8 上运行

Question

当我在 iOS 9 中打开 Paypal for Payment Gateway 时，我的应用程序崩溃了，但它在 iOS 7 和 8 上运行。
如何解决？

由于未捕获的异常“NSRangeException”而终止应用程序，原因： '-[NSTaggedPointerString getCharacters:range:]: Range {0, 7} out of 界限；字符串长度 6'

您是否从 PayPal 开发者网站下载了新框架？ 如果是，则使用以下代码：

    self.completedPayment = nil;
    NSMutableArray *items = [[NSMutableArray alloc] init];

    for (Products *product in appDelegate.arrCartItems) {
        PayPalItem *item1 = [PayPalItem itemWithName:product.productName
                                        withQuantity:[product.productSST intValue]
                                           withPrice:[[NSDecimalNumber alloc] initWithString:[NSString stringWithFormat:@"%.2f",[product.productSP floatValue]]]
                                        withCurrency:@"USD"
                                             withSku:@"Photos & Videos-00037"];
        //                        NSArray *items = @[item1];
        [items addObject:item1];
    }
    //                float orderPrice = [orderTotal floatValue];
    //                NSLog(@"orderPrice: %f",orderPrice);


    NSDecimalNumber *subtotal = [PayPalItem totalPriceForItems:items];
    // Optional: include payment details
    NSDecimalNumber *shipping = [[NSDecimalNumber alloc] initWithString:@"50.00"];
    NSDecimalNumber *tax = [[NSDecimalNumber alloc] initWithString:@"0.00"];
    PayPalPaymentDetails *paymentDetails = [PayPalPaymentDetails paymentDetailsWithSubtotal:subtotal
                                                                               withShipping:shipping
                                                                                    withTax:tax];

    NSDecimalNumber *totalAmount = [[subtotal decimalNumberByAdding:shipping] decimalNumberByAdding:tax];

    PayPalPayment *payment = [[PayPalPayment alloc] init];
    payment.amount = totalAmount;
    payment.currencyCode = @"USD";
    payment.shortDescription = @"Item Details";
    payment.items = items;  // if not including multiple items, then leave payment.items as nil
    payment.paymentDetails = paymentDetails; // if not including payment details, then leave payment.paymentDetails as nil

    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.
    }

    // Update payPalConfig re accepting credit cards.
    self.payPalConfig.acceptCreditCards = self.acceptCreditCards;

    PayPalPaymentViewController *paymentViewController = [[PayPalPaymentViewController alloc] initWithPayment:payment
                                                                                                configuration:self.payPalConfig
                                                                                                     delegate:self];
    [self presentViewController:paymentViewController animated:YES completion:nil];
