ios - 对于ApplePay PaymentAuthorizationViewController委托(delegate)，创建的零PKSummaryItem

关于此question，感谢您缩小范围。但是可惜我必须配置这个委托

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
               didSelectShippingMethod:(PKShippingMethod *)shippingMethod
completion:(void (^)(PKPaymentAuthorizationStatus, NSArray *summaryItems))completion
{
    completion(PKPaymentAuthorizationStatusSuccess, [self summaryItemsForShippingMethod:shippingMethod]);
}

- (NSArray *)summaryItemsForShippingMethod:(PKShippingMethod *)shippingMethod
{
    totalPrice = 5;
    NSString *prices = [NSString stringWithFormat:@"%d",totalPrice];
    NSDecimalNumber *num = [[NSDecimalNumber alloc] initWithString:prices];
    PKPaymentSummaryItem *foodItem = [PKPaymentSummaryItem summaryItemWithLabel:@"Total Products Cost" amount:num];
    NSDecimalNumber *total = [foodItem.amount decimalNumberByAdding:shippingMethod.amount];
    PKPaymentSummaryItem *totalItem = [PKPaymentSummaryItem summaryItemWithLabel:@"Video Mantis Productions, INC." amount:total];
    return @[foodItem, shippingMethod, totalItem];
}

为了向用户展示什么是产品摘要。可悲的是，我将PKPaymentSummaryItem * foodItem设置为nil，因此该处理程序从未得到修复。请帮忙！先感谢您。

最佳答案

那么答案，是吗？我使用Stripe作为与ApplePay进行交易的中间媒介，因此也使用其SDK和教程来设置ApplePay。无论如何，Passkit的PKPaymentAuthorizationViewController使用可以配置的两个独立协议，以帮助简化实现。我同时使用了两者；

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
                   didSelectShippingMethod:(PKShippingMethod *)shippingMethod
                                completion:(void (^)(PKPaymentAuthorizationStatus status, NSArray *summaryItems))completion;

和...

- (void)paymentAuthorizationViewController:(PKPaymentAuthorizationViewController *)controller
                  didSelectShippingAddress:(ABRecordRef)address
                                completion:(void (^)(PKPaymentAuthorizationStatus status, NSArray *shippingMethods, NSArray *summaryItems))completion;

但是，我注意到的是调用后一个时机，即didSelectShippingAddress，Passkit类停滞了，所以我将其删除，仅使用了第一个即didSelectShippingMethod来帮助实现整个过程，并且无限处理从未发生过。再次！希望它也对您有用（：
