I have an app which has inApp purchase feature. The problem is even if I get error, such as the fail case because of "Cannot connect to iTunes Store", the system dialog says "You are all set. Your purchase was successful". You can find my inApp purchase helper class code down.
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions {
switch (transaction.transactionState) {
case .purchased:
NotificationCenter.default.post(name: .IAPHelperSetPepqueenNotification, object: nil)
if let url = Bundle.main.appStoreReceiptURL {
guard let receipt = try? Data(contentsOf: url) else {
print("error to take receipt")
return
}
let receiptData: String = receipt.base64EncodedString(options: .init(rawValue: 0))
PepappNetwork.request(target: .postReceipt(platform: "ios", receipt: receiptData) , success: { (JSON) in
print(JSON)
let user = User(JSON: JSON["data"].dictionaryObject!)
UserDefaults.standard.set(user?.identifier, forKey: "userID")
user?.persist()
if user?.language != nil {
UserDefaults.standard.set(user!.language!, forKey: "forcedLanguage")
UserDefaults(suiteName: Constants.UserDefaults.containerName)!.set(user!.language!, forKey: "forcedLanguage")
}
NotificationCenter.default.post(name: Notification.Name.CurrentUserChanged, object: nil)
self.complete(transaction: transaction)
}, error: { (errorString, _) in
}) { (MoyaError) in
}
}
break
case .failed:
NotificationCenter.default.post(name: .IAPHelperCancelNotification, object: nil)
fail(transaction: transaction)
break
case .restored:
restore(transaction: transaction)
break
case .deferred:
break
case .purchasing:
break
}
}
}
Fail transaction func
private func fail(transaction: SKPaymentTransaction) {
print("fail...")
if let transactionError = transaction.error as NSError?,
let localizedDescription = transaction.error?.localizedDescription,
transactionError.code != SKError.paymentCancelled.rawValue {
print("Transaction Error: \(localizedDescription)")
}
Before app enter update transactions function "You're all set." dialog has already been show.
