本文介绍了我的 IAP 不工作.func Paymentqueue 中的错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我点击我的任何一个 IAPS 时，会出现一条消息，指出该 IAP 已被购买(事实并非如此)并将免费恢复，然后什么也没有发生，IAP 不会执行.
When I click on either of my IAPS, a message appears saying the IAP was already purchased (which is not the case) and will be restored for free, then nothing happens, the IAP doesn't execute.
这是我在控制台中得到的:
Here is what I get in my console:
No Value.
IAP is enabled, loading...
true
Product Request
Product Added
IAP id
Remove Ads
Removes ads from the app.
2
Buy: IAP id
Add Payment
nil
default: Error
这是我的代码:

推荐答案
我找到了解决方案！
删除
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
在你拥有它的任何地方，并把它放在一个地方，每次你的应用启动时它都会执行一次(只有一次)(我把它放在 viewDidLoad() 中).
everywhere you have it and put it once (ONLY ONCE) in a place where it will be executed each time your app boots up ( I put it in viewDidLoad()).
这将检查所有未完成的交易并在应用加载后终止它们，从而在您的用户触发 IAP 之前消除任何可能的错误.
This will check for all unfinished transactions and terminate them once the app has loaded, thus removing any possible errors before your users triggers an IAP.

P.S.:另外，这不是我的问题，但请确保为每个 PurchaseState 执行 FinishTransaction()，如下所示:
P.S.: Also, this wasn't my issue, but make sure to finishTransaction() for each PurchaseState like here:
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
print("Add Payment")
for transaction:AnyObject in transactions{
let trans = transaction as! SKPaymentTransaction
print(trans.error)
switch trans.transactionState{
case .Purchased:
print("IAP unlocked")
print(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID{
case "IAP id":
print("Keep on")
keepOn()
default:
print("IAP not setup")
}
queue.finishTransaction(trans)
break
case .Failed:
print ("Buy error")
queue.finishTransaction(trans)
break
default:
print("default: Error")
break
}
}
}
永远不要忘记这一点:
queue.finishTransaction(trans)
