Xcode Apple Pay - PKPaymentAuthorizationViewControllerDelegate問題

Question

我試圖將Apple Pay實施到我的應用程序中。我有一個問題，甚至在我的ViewController.swift文件中建立了PKPaymentAuthorizationViewControllerDelegate。

大多數代碼樣本顯示它：class ViewController: UITableViewController, PKPaymentAuthorizationViewControllerDelegate

這裏是我的代碼：

class ApplePayVC: UIViewController, PKPaymentAuthorizationViewControllerDelegate { 

Answer 1

那是因爲你必須實現某些代表的功能。

看到蘋果文檔：https://developer.apple.com/library/prerelease/ios/documentation/PassKit/Reference/PKPaymentAuthorizationViewControllerDelegate_Ref/index.html

兩個功能是必需的：

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

必須覆蓋它們，然後，錯誤將消失Xcode

Answer 2

只需添加以下funcs中

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

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

OR

像這樣創建

import Foundation 

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

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