paypal小坑

paypal完成回调

#pragma mark - 已经完成paypal支付
- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
    DLog(@"已经完成paypal支付%@",completedPayment);
    [self showSuccess];
    [self sendCompletedPaymentToServer:completedPayment]; // Payment was processed successfully; send to server for verification and fulfillment
    [self dismissViewControllerAnimated:YES completion:nil];
}
- (void)sendCompletedPaymentToServer:(PayPalPayment *)completedPayment {
    // TODO: Send completedPayment.confirmation to server
    NSLog(@"Here is your proof of payment:\n\n%@\n\nSend this to your server for confirmation and fulfillment.", completedPayment.confirmation);
}

#pragma mark - 取消paypal支付
- (void)payPalPaymentDidCancel:(PayPalPaymentViewController *)paymentViewController {
    NSLog(@"PayPal Payment Canceled");
    self.successView.hidden = YES;
    [self dismissViewControllerAnimated:YES completion:nil];
}

#pragma mark - 将要完成paypal支付
- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController willCompletePayment:(PayPalPayment *)completedPayment completionBlock:(PayPalPaymentDelegateCompletionBlock)completionBlock {

}

已经完成和将要完成paypal支付不可同时出现,不然会不走已经完成paypal支付的方法.
