我已经实现了最新的 PayPal API,但每次我尝试通过 PayPal 的沙箱进行支付时,支付都会卡在“处理中”。完全难住了。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
}
最佳答案
你的issue是在willCompletePayment
的completion block中,你需要在处理完成后返回completion block
调用 didCompletePayment
来自Paypal代码文档
Your code MUST finish by calling the completionBlock.
completionBlock Block to execute when your processing is done.
所以你的代码会像
- (void)payPalPaymentViewController:(nonnull PayPalPaymentViewController *)paymentViewController
willCompletePayment:(nonnull PayPalPayment *)completedPayment
completionBlock:(nonnull PayPalPaymentDelegateCompletionBlock)completionBlock {
//do all the code you want
completionBlock();
}
在你写完这个完成 block 后,它会转到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];
}
另一种选择
查看Paypal示例代码,willCompletePayment
方法并不是必须要实现的,可以跳过这个方法,直接写didCompletePayment
这样你的代码可以是这样的:
- (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
Your code MAY deal with the completedPayment, if it did not already do so within your optional payPalPaymentViewController:willCompletePayment:completionBlock: method.
通过使用该方法,您无需调用 willCompletePayment
方法,您将不会遇到您曾遇到的问题。
