解决方法:
原因:可能是网络延迟或者支付终端处理速度慢。
解决方法:
以下是一个简单的示例代码,展示如何在iOS应用中集成Apple Pay:
import PassKit
class ViewController: UIViewController, PKPaymentAuthorizationViewControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
if PKPaymentAuthorizationViewController.canMakePayments() {
let request = PKPaymentRequest()
request.countryCode = "US"
request.currencyCode = "USD"
request.merchantIdentifier = "your.merchant.identifier"
request.supportedNetworks = [.visa, .masterCard, .amex]
request.merchantCapabilities = .capability3DS
let item = PKPaymentSummaryItem(label: "Item", amount: NSDecimalNumber(decimal: 19.99))
request.paymentSummaryItems = [item]
let authViewController = PKPaymentAuthorizationViewController(paymentRequest: request)
authViewController?.delegate = self
present(authViewController!, animated: true, completion: nil)
}
}
func paymentAuthorizationViewControllerDidFinish(_ controller: PKPaymentAuthorizationViewController) {
dismiss(animated: true, completion: nil)
}
func paymentAuthorizationViewController(_ controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, handler completion: @escaping (PKPaymentAuthorizationResult) -> Void) {
// 处理支付授权
let result = PKPaymentAuthorizationResult(status: .success, errors: nil)
completion(result)
}
}
