我在应用程序购买中练习从屏幕上删除iAds购买简单运行一个名为删除广告的功能。它只是将练习/测试iAd设置到屏幕外的位置，问题是这是我第一次在应用程序购买中。我在应用程序中购买了iTunes连接，但我可以在这里工作。现在有人怎么做应用程序购买？谢谢我在Xcode中使用swift，GoHome SKlabel简单地将您带回主屏幕，所以不要介意。我正在使用SpritKit。

在此处查看我的问题和答案：My IAP isn't working. Bugs at func Paymentqueue
它包含用于移除广告的IAP的工作代码和一些提示。我希望能帮到你！
以下是完整的IAP代码：
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"){
p = product
buyProduct()
break
}
}
}
@IBAction func restorePurchases(sender: UIButton) {
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
//IAP Functions
var list = [SKProduct]()
var p = SKProduct()
func removeAds(){
banner.removeFromSuperview()
bannerGoogle.removeFromSuperview()
outRemoveAds.removeFromSuperview()
outRestorePurchases.removeFromSuperview()
let theValue = 10
NSUserDefaults.standardUserDefaults().setObject(theValue, forKey: "val")
NSUserDefaults.standardUserDefaults().synchronize()
}
func buyProduct(){
print("Buy: "+p.productIdentifier)
let pay = SKPayment (product: p)
SKPaymentQueue.defaultQueue().addPayment(pay as SKPayment)
}
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
print("Product Request")
let myProduct = response.products
for product in myProduct{
print("Product Added")
print(product.productIdentifier)
print(product.localizedTitle)
print(product.localizedDescription)
print(product.price)
list.append(product as SKProduct)
}
}
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("Remove Ads")
removeAds()
default:
print("IAP not setup")
}
queue.finishTransaction(trans)
break
case .Failed:
print ("Buy error")
queue.finishTransaction(trans)
break
default:
print("default: Error")
break
}
}
}
func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) {
print("Purchases Restored")
_ = []
for transaction in queue.transactions {
let t: SKPaymentTransaction = transaction as SKPaymentTransaction
let prodID = t.payment.productIdentifier as String
switch prodID{
case "IAP id":
print("Remove Ads")
removeAds()
default:
print("IAP not setup")
}
}
}
func finishTransaction(trans:SKPaymentTransaction){
print("Finshed Transaction")
}
func paymentQueue(queue: SKPaymentQueue, removedTransactions transactions: [SKPaymentTransaction]) {
print("Remove Transaction")
}
}
放：
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
在viewDidLoad或viewDidAppear
中
