我正在使用最新的iOS Paypal SDK，尝试在沙盒环境中测试登录和付款交易。我已经在沙盒测试账户页面创建了一个商业账户。因此，我有一个用户电子邮件、密码和签名。但是我无法使用这些凭据登录。我收到以下响应错误：
PayPal SDK: Request has failed with error: invalid_user - Incorrect username/password. Please try again. (401) | PayPal Debug-ID: c3dd83c83d43e | Details: (
{
"error_description" = "Invalid user credentials";
}
).
我无法理解凭据无效的原因。在使用iOS SDK登录沙盒账户时，我需要使用哪些凭据？或者我的代码有什么问题吗？

if (!payment.processable) {
// This particular payment will always be processable. If, for

// to handle that here.
[[[UIAlertView alloc] initWithTitle:@"Message" message:@"Payment is unprocessable" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] show];
return;
}
PayPalPaymentViewController *paymentViewController = [[PayPalPaymentViewController alloc] initWithPayment:payment configuration:self.payPalConfig delegate:self];
[self presentViewController:paymentViewController animated:YES completion:nil];
}
#pragma mark PayPalPaymentDelegate methods
- (void)payPalPaymentViewController:(PayPalPaymentViewController *)paymentViewController didCompletePayment:(PayPalPayment *)completedPayment {
NSLog(@"PayPal Payment Success!");
self.resultText = [completedPayment description];
[[[UIAlertView alloc] initWithTitle:@"Message" message:@"Please enter amount to proceed" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] show];
[self sendCompletedPaymentToServer:completedPayment]; // Payment was processed successfully; send to server for verification and fulfillment

// 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);
}
注意: 我已经使用PayPal沙箱环境的PayPal客户端ID初始化了PayPalMobile。
附加问题:
merchantName应该包含什么？是否应与PayPal网站上提到的相同？
