我创建了一个新的沙盒测试用户来测试恢复购买按钮，但是当我按下它并输入我的密码或当我按下取消时，级别仍然解锁。我不明白为什么会发生这种情况。有人可以看一下我的代码并告诉我我做错了什么吗？谢谢!
func RestorePurchases() {
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
println("Can't make purchases")
}
func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue!) {
println("transactions restored")
var purchasedItemIDS = []
for transaction in queue.transactions {
var t: SKPaymentTransaction = transaction as! SKPaymentTransaction
let prodID = t.payment.productIdentifier as String
switch prodID {
case "unlockLevelTwo":
println("restoreleveltwo")
NSUserDefaults().setBool(true, forKey: "Leavel2")
unlockLevelTwoPlease()
case "unlockLevelThree":
println("restorelevelthree")
NSUserDefaults().setBool(true, forKey: "Leavel3")
unlockLevelThreePlease()
default:
println("IAP not setup")
let alert = UIAlertView()
alert.title = "Oops"
alert.message = "There are no purchases to restore, please buy one"
alert.addButtonWithTitle("Cancel")
alert.show()
}
}
}
//EDITED MORE CODE....
func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) {
println("Received Payment Transaction Response from Apple");
for transaction:AnyObject in transactions {
var trans = transaction as! SKPaymentTransaction
println(trans.error)
switch trans.transactionState {
case .Purchased:
let prodID = p.productIdentifier as String
switch prodID {
case "unlockLevelTwo":
println("unlocksleveltwo")
NSUserDefaults().setBool(true, forKey: "Leavel2")
unlockLevelTwoPlease()
case "unlockLevelThree":
println("unlocklevelthree")
NSUserDefaults().setBool(true, forKey: "Leavel3")
unlockLevelThreePlease()
default:
println("")
}
queue.finishTransaction(trans)
break;
case .Failed:
println("Purchased Failed");
queue.finishTransaction(trans)
break;
case .Restored:
let prodID = p.productIdentifier as String
switch prodID {
case "unlockLevelTwo":
println("unlocksleveltwo")
NSUserDefaults().setBool(true, forKey: "Leavel2")
unlockLevelTwoPlease()
case "unlockLevelThree":
println("unlocklevelthree")
NSUserDefaults().setBool(true, forKey: "Leavel3")
unlockLevelThreePlease()
default:
println("")
}
default:
println("default")
break;
}
}
}
最佳答案
我认为你的方法不对。
根据 Apple 文档，paymentQueueRestoreCompletedTransactionsFinished 告诉观察者支付队列已完成发送恢复交易。在支付队列处理完所有可恢复交易后调用此方法。您的应用程序无需在此方法中执行任何操作。
我想您已经实现了 paymentQueue:updatedTransactions。您应该检查 transactionState SKPaymentTransactionStateRestored 并在那里解锁您的关卡。
关于ios - 为什么在我没有购买任何应用程序内购买时购买会恢复？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30721881/
