对于 ApplePay paymentAuthorizationViewController 委托创建 nil PKSummaryItem

Question

关于此，感谢您缩小范围。但遗憾的是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];
}

为了向用户展示真正的产品摘要。遗憾的是，我得到的 PKPaymentSummaryItem *foodItem 为 nil，因此处理过程永远不会得到修复。请帮忙！提前谢谢你。

Answer 1

PKPaymentSummaryItem 可从 iOS 8 获得，因此如果您尝试将其与较新的 iOS 版本一起使用，您将得到 nil 而不是预期值。

我也被这个卡住了

Answer 2

那么答案，嗯？我使用 Stripe 作为与 ApplePay 交易的中间媒介，因此使用他们的 SDK 和教程来设置 ApplePay。无论如何，Passkit 的 PKPaymentAuthorizationViewController 使用两个单独的协议，可以配置这些协议以帮助简化实施。我同时使用了两者，即；

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

还有...

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

然而，我注意到的是当调用后一个时，即 didSelectShippingAddress，Passkit 有点停滞，所以我删除了它，只使用了第一个 didSelectShippingMethod 来帮助实现整个事情，无限处理再也没有发生过！希望它也适合你 (:
