使用 SwiftyStoreKit 自动更新

问题描述

SwiftyStoreKit 对我来说是一个非常困难的产品，因为将近一周，我在 StackOverflow、YouTube 和 Google 上到处搜索答案。我找不到任何答案，因为我正在研究 Auto-Renewable，我试图找出用户是否取消订阅或过期，应用程序会要求重新订阅。在测试期间，购买效果很好，但我需要弄清楚应用程序如何知道订阅是否已过期。每次我尝试验证时，我的验证收据总是返回以下错误消息。我做错了什么？

Receipt verification Failed: receiptInvalid(receipt: ["status": 21002],status: SwiftyStoreKit.ReceiptStatus.malformedOrMissingData)

这是我的顶级代码：

import SwiftyStoreKit

var sharedSecret = " * My shared Secret * "
let appleValidator = AppleReceiptValidator(service: .sandBox,sharedSecret: sharedSecret)

enum RegisteredPurchase: String {
    case autoRenewable = " * My Auto-Renewable Bundle ID * "
}

购买时带有按钮的代码

@objc func startSub() {
   StoreManager.shared.purchase(purchase: RegisteredPurchase.autoRenewable)
}

AppDelegate.swift

SwiftyStoreKit.completeTransactions(atomically: true) { purchaseStatus in
   for products in purchaseStatus {
      switch products.transaction.transactionState {
      case .purchased,.restored:
         if products.needsFinishTransaction {
            SwiftyStoreKit.finishTransaction(products.transaction)
         }
      default: break
      }
   }
}

SwiftyStoreKit.verifyReceipt(using: appleValidator) { result in
   switch result {
   case .success(let receipt):
      let productID = Set([RegisteredPurchase.autoRenewable.rawValue])
      let purchaseResult = SwiftyStoreKit.verifySubscriptions(productIds: productID,inReceipt: receipt)
      switch purchaseResult {
      case .purchased(let expiryDate,let items):
         print("\(productID) are valid until \(expiryDate),\(items).")
      case .expired(let expiryDate,let items):
         print("\(productID) are expired since \(expiryDate),\(items).")
      case .notPurchased:
         print("The product has never purchased...")
      }
   case .error(let error):
      print("Receipt verification Failed: \(error)")
   }
}

StoreKitManager.swift

class StoreManager: NSObject {
   @objc static let shared = StoreManager()

   func getInfo(purchase: RegisteredPurchase) {
      SwiftyStoreKit.retrieveProductsInfo([purchase.rawValue],completion: { result in
         if result.error == nil {
            for x in result.retrievedProducts {
               print("Get information: \(x.localizedTitle)")
            }
         } else {
             print("Error getting information")
         }
      })
   }

   func purchase(purchase: RegisteredPurchase) {
      SwiftyStoreKit.purchaseProduct(purchase.rawValue,completion: { result in
          if case .success(let product) = result {
              if product.needsFinishTransaction {
                  SwiftyStoreKit.finishTransaction(product.transaction)
              }
              print("Purchasing: \(result)")
              self.purchaseResult(result: result)
          }
