我不明白为什么我的应用程序被拒绝，即使我在应用内购买中使用了恢复购买代码。请告诉我我错在哪里，下面是我的代码：-
public typealias ProductIdentifier = String
public typealias ProductsRequestCompletionHandler = (_ success: Bool, _ products: [SKProduct]?) -> ()
open class IAPHelper : NSObject {
static let IAPHelperPurchaseNotification = "IAPHelperPurchaseNotification"
fileprivate let productIdentifiers: Set<ProductIdentifier>
fileprivate var purchasedProductIdentifiers = Set<ProductIdentifier>()
fileprivate var productsRequest: SKProductsRequest?
fileprivate var productsRequestCompletionHandler: ProductsRequestCompletionHandler?
public init(productIds: Set<ProductIdentifier>) {
productIdentifiers = productIds
for productIdentifier in productIds {
let purchased = UserDefaults.standard.bool(forKey: productIdentifier)
if purchased {
purchasedProductIdentifiers.insert(productIdentifier)
print("Previously purchased: (productIdentifier)")
} else {
print("Not purchased: (productIdentifier)")
}
}
super.init()
SKPaymentQueue.default().add(self)
}
}
// MARK: - StoreKit API
extension IAPHelper {
public func requestProducts(completionHandler: @escaping ProductsRequestCompletionHandler) {
productsRequest?.cancel()
productsRequestCompletionHandler = completionHandler
productsRequest = SKProductsRequest(productIdentifiers: productIdentifiers)
productsRequest!.delegate = self
productsRequest!.start()
}
public func buyProduct(_ product: SKProduct) {
print("Buying (product.productIdentifier)...")
let payment = SKPayment(product: product)
SKPaymentQueue.default().add(payment)
}
public func isProductPurchased(_ productIdentifier: ProductIdentifier) -> Bool {
return purchasedProductIdentifiers.contains(productIdentifier)
}
public class func canMakePayments() -> Bool {
return SKPaymentQueue.canMakePayments()
}
public func restorePurchases() {
SKPaymentQueue.default().restoreCompletedTransactions()
}
}
// MARK: - SKProductsRequestDelegate
extension IAPHelper: SKProductsRequestDelegate {
public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {
let products = response.products
print("Loaded list of products...")
productsRequestCompletionHandler?(true, products)
clearRequestAndHandler()
for p in products {
print("Found product: (p.productIdentifier) (p.localizedTitle) (p.price.floatValue)")
}
}
public func request(_ request: SKRequest, didFailWithError error: Error) {
print("Failed to load list of products.")
print("Error: (error.localizedDescription)")
productsRequestCompletionHandler?(false, nil)
clearRequestAndHandler()
}
private func clearRequestAndHandler() {
productsRequest = nil
productsRequestCompletionHandler = nil
}
}
// MARK: - SKPaymentTransactionObserver
extension IAPHelper: SKPaymentTransactionObserver {
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
switch (transaction.transactionState) {
case .purchased:
complete(transaction: transaction)
break
case .failed:
fail(transaction: transaction)
break
case .restored:
restore(transaction: transaction)
break
case .deferred:
break
case .purchasing:
break
}
}
}
public func paymentQueue(_ queue: SKPaymentQueue, shouldAddStorePayment payment: SKPayment, for: SKProduct) -> Bool {
return true
}
private func complete(transaction: SKPaymentTransaction) {
print("complete...")
deliverPurchaseNotificationFor(identifier: transaction.payment.productIdentifier)
SKPaymentQueue.default().finishTransaction(transaction)
}
private func restore(transaction: SKPaymentTransaction) {
guard let productIdentifier = transaction.original?.payment.productIdentifier else { return }
print("restore... (productIdentifier)")
deliverPurchaseNotificationFor(identifier: productIdentifier)
SKPaymentQueue.default().finishTransaction(transaction)
}
private func fail(transaction: SKPaymentTransaction) {
print("fail...")
if let transactionError = transaction.error as? NSError {
if transactionError.code != SKError.paymentCancelled.rawValue {
print("Transaction Error: (transaction.error?.localizedDescription)")
}
}
SKPaymentQueue.default().finishTransaction(transaction)
}
private func deliverPurchaseNotificationFor(identifier: String?) {
guard let identifier = identifier else { return }
purchasedProductIdentifiers.insert(identifier)
UserDefaults.standard.set(true, forKey: identifier)
UserDefaults.standard.synchronize()
NotificationCenter.default.post(name: NSNotification.Name(rawValue: IAPHelper.IAPHelperPurchaseNotification), object: identifier)
}
}
您应该添加这样的"恢复购买"按钮，用户应该能够在应用程序界面中看到它。
您不仅需要致电SKPaymentQueue.default().restoreCompletedTransactions()但也要实现还原本身(我的意思是，向用户提供内容(。
