我已经制作了一款应用,并为优质版本进行了应用内购买。因为我无法在模拟器中测试应用内购买。
所以这是我的代码:
class settingsViewController: UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver, ADBannerViewDelegate {
@IBOutlet var adBennerView: ADBannerView!
@IBOutlet var outletRemoveAds: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
if(SKPaymentQueue.canMakePayments()) {
println("IAP is enabled, loading")
var productID:NSSet = NSSet(objects: "xxx")
var request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as Set<NSObject>)
request.delegate = self
request.start()
} else {
println("please enable IAPS")
}
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func removeAds(sender: AnyObject) {
for product in list {
var prodID = product.productIdentifier
if(prodID == "xxx") {
p = product
buyProduct()
break;
}
}
}
@IBAction func restorePurchases(sender: AnyObject) {
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
var list = [SKProduct]()
var p = SKProduct()
func buyProduct() {
println("buy " + p.productIdentifier)
var pay = SKPayment(product: p)
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().addPayment(pay as SKPayment)
}
func productsRequest(request: SKProductsRequest!, didReceiveResponse response: SKProductsResponse!) {
println("product request")
var myProduct = response.products
for product in myProduct {
println("product added")
println(product.productIdentifier)
println(product.localizedTitle)
println(product.localizedDescription)
println(product.price)
list.append(product as! SKProduct)
}
outletRemoveAds.enabled = true
}
func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) {
println("add paymnet")
for transaction:AnyObject in transactions {
var trans = transaction as! SKPaymentTransaction
println(trans.error)
switch trans.transactionState {
case .Purchased:
println("buy, ok unlock iap here")
println(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID {
case "xxx":
println("remove ads")
removeAds()
isPremium = true
default:
println("IAP not setup")
}
queue.finishTransaction(trans)
break;
case .Failed:
println("buy error")
queue.finishTransaction(trans)
break;
default:
println("default")
break;
}
}
}
func finishTransaction(trans:SKPaymentTransaction)
{
println("finish trans")
SKPaymentQueue.defaultQueue().finishTransaction(trans)
}
func paymentQueue(queue: SKPaymentQueue!, removedTransactions transactions: [AnyObject]!)
{
println("remove trans");
}
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 "xxx":
println("remove ads")
removeAds()
isPremium = true
default:
println("IAP not setup")
}
}
}
func removeAds() {
adBennerView!.removeFromSuperview()
}
如果用户购买了高级版本 - isPremium
变为true
,那么我怎么知道每次用户登录isPremium
时仍然如此?
答案 0 :(得分:0)
这是因为您只将isPremium
存储在RAM而不是其他任何地方。尝试使用NSUserDefaults
来实现这一目的,只是为了看看它是如何完成的(实际上建议不要将NSUserDefaults
用于那种类型的信息,因为它很容易入侵,但你必须明白存储有关您的应用状态的信息的基础知识。)
