Question

我已经实施了最新的PayPal API，但每当我尝试通过PayPal的沙箱运行付款时，付款就会停留在“处理”上。完全难倒。谢谢！

-(void)payWithPayPal {
    NSString *shortDescription = [NSString stringWithFormat:@"%i %@", [Global sharedInstance].currentOrder.itemQuantity, [Global sharedInstance].currentOrder.boozeBrand];
    NSDecimalNumber *paymentDecimal = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:@"%.02f", [Global sharedInstance].currentOrder.itemPrice]];
    NSString *sku = [NSString stringWithFormat:@"DBAR-%i", [Global sharedInstance].currentOrder.orderNumber];

    NSString *name = [NSString stringWithFormat:@"%@", [Global sharedInstance].currentOrder.boozeBrand];
    PayPalItem *item = [PayPalItem itemWithName:name
                                withQuantity:[Global sharedInstance].currentOrder.itemQuantity
                                       withPrice:paymentDecimal
                                    withCurrency:@"USD"
                                         withSku:sku];
    float priceFloat = [item.price floatValue];
    float totalFloat = priceFloat * item.quantity;
    NSDecimalNumber *total = [NSDecimalNumber decimalNumberWithString:[NSString stringWithFormat:@"%.02f", totalFloat]];

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

    if (!payment.processable) {NSLog(@"Payment not processable.");}

    // Update payPalConfig re accepting credit cards.

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


#pragma mark - PayPalDelegate

-(void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController willCompletePayment:(PayPalPayment *)completedPayment completionBlock:(PayPalPaymentDelegateCompletionBlock)completionBlock {
    NSLog(@"Payment processing.");
    //Stuck on this forever - this is what I'm trying to get past
}

-(void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
    //Never gets here
}

您的问题出现在willCompletePayment的完成块中，您需要在完成处理后返回完成块拨打didCompletePayment

来自Paypal代码文档

您的代码必须通过调用completionBlock来完成 completionBlock在处理完成后执行的块。

所以你的代码就像

- (void)payPalPaymentViewController:(nonnull PayPalPaymentViewController *)paymentViewController
                willCompletePayment:(nonnull PayPalPayment *)completedPayment
                    completionBlock:(nonnull PayPalPaymentDelegateCompletionBlock)completionBlock {
    //do all the code you want
    completionBlock();
}

写完这个完成块后，它将转到didCompletePayment，可以是这样的：

- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
  NSLog(@"PayPal Payment Success!");
  self.resultText = [completedPayment description];
  [self showSuccess];
  [self dismissViewControllerAnimated:YES completion:nil];
}

另一个选项 通过检查Paypal示例代码，实现willCompletePayment方法不是必须的，您可以跳过此方法直接写didCompletePayment

这样你的代码就像这样：

- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
  NSLog(@"PayPal Payment Success!");
  self.resultText = [completedPayment description];
  [self showSuccess];

  [self sendCompletedPaymentToServer:completedPayment]; // Payment was processed successfully; send to your server for verification and fulfillment
  [self dismissViewControllerAnimated:YES completion:nil];
}

来自Paypal的didCompletePayment的代码文档

您的代码可以处理completedPayment，如果它还没有在你的选择范围内 payPalPaymentViewController：willCompletePayment：completionBlock：方法

通过使用该方法，您无需调用willCompletePayment方法，也不会遇到您遇到的问题。
