篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了我的IAP没有用。在func Paymentqueue的错误相关的知识，希望对你有一定的参考价值。
当我点击我的任何一个IAPS时，会出现一条消息，说明已经购买了IAP（情况并非如此）并且将免费恢复，然后没有任何反应，IAP不会执行。
这是我在我的控制台中得到的：
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：
GameViewController.Swift
import UIKit
import StoreKit
class GameViewController: UIViewController, ADBannerViewDelegate, SKProductsRequestDelegate, SKPaymentTransactionObserver, GKGameCenterControllerDelegate,GADBannerViewDelegate{
@IBOutlet var outRemoveAds: UIButton!
@IBOutlet var outRestorePurchases: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(animated)
if NSUserDefaults.standardUserDefaults().objectForKey("val") != nil {
print("Has a value.")
banner.removeFromSuperview()
bannerGoogle.removeFromSuperview()
outRemoveAds.removeFromSuperview()
outRestorePurchases.removeFromSuperview()
removeInterFrom = 1
}
else {
print("No Value.")
}
if(SKPaymentQueue.canMakePayments()){
print("IAP is enabled, loading...")
let productID:NSSet = NSSet(objects:"IAP id")
let request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>)
request.delegate = self
request.start()
}
else{
print("Please enable IAPS")
}
}
//IAP Ads
@IBAction func removeAds(sender: UIButton) {
for product in list{
let prodID = product.productIdentifier
if (prodID == "IAP id"){

break
}

}

SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()

//IAP Functions

func removeAds(){

答案
我找到了解决方案！
删除
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
无论你到哪里，只需将它放一次（仅限一次），每次应用程序启动时都会执行它（我把它放在viewDidLoad（）中）。
这将检查所有未完成的事务，并在应用程序加载后终止它们，从而在用户触发IAP之前删除任何可能的错误。
（如果这个答案，或者这个问题帮助了你，请不要忘记upvote;））
P.S。：另外，这不是我的问题，但请确保为每个PurchaseState完成事务处理（），如下所示：
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
}
}
}
别忘了这个：
queue.finishTransaction(trans)
