Xcode Apple Pay - PKPaymentAuthorizationViewControllerDelegate问题

Question

我正在尝试将Apple Pay实施到我的应用程序中。即使在我的PKPaymentAuthorizationViewControllerDelegate文件中建立ViewController.swift，我也遇到了问题。

大多数代码示例都将其显示为：class ViewController: UITableViewController, PKPaymentAuthorizationViewControllerDelegate

这是我的代码：

class ApplePayVC: UIViewController, PKPaymentAuthorizationViewControllerDelegate {

Answer 1

那是因为你必须实现委托的一些功能。

请参阅Apple文档：https://developer.apple.com/library/prerelease/ios/documentation/PassKit/Reference/PKPaymentAuthorizationViewControllerDelegate_Ref/index.html

需要两个功能：

• paymentAuthorizationViewController(_:didAuthorizePayment:completion:)
• paymentAuthorizationViewControllerDidFinish(_:)

您必须覆盖它们，然后，错误将从Xcode中消失

Answer 2

只需添加以下功能

即可

Camera.CFrame

OR

像这样创建一个新的.swift文件

    internal func paymentAuthorizationViewController(controller: PKPaymentAuthorizationViewController, didAuthorizePayment payment: PKPayment, completion: ((PKPaymentAuthorizationStatus) -> Void)) {
        completion(PKPaymentAuthorizationStatus.Success)
    }

    internal func paymentAuthorizationViewControllerDidFinish(controller: PKPaymentAuthorizationViewController) {
        controller.dismissViewControllerAnimated(true, completion: nil)
    }
