购买完成后，我正在使用此代码解锁一个场景。我的第一个问题是代码是否正确，购买是否有效。我的第二个问题是我要求在按下精灵节点时发生购买，我是否在触摸开始时调用了正确的函数？以下所有代码均在SKScene
中 var list = [SKProduct]()
var p = SKProduct()
override func didMoveToView(view: SKView) {
if(SKPaymentQueue.canMakePayments()) {
println("IAP is enabled, loading")
var productID:NSSet = NSSet(objects: "_Scene1_Unlock")
var request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as Set<NSObject>)
request.delegate = self
request.start() } else {
println("please enable IAPS") }
}
func addScene1() {
println("scene1 added") }
func RestorePurchases() {
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions() }
func btnAddScene1() {
for product in list {
var prodID = product.productIdentifier
if(prodID == "_Scene1_Unlock") {
p = product
buyProduct()
break; } } }
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) } }
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 "_Scene1_Unlock":
println("remove ads")
addScene1()
default:
println("IAP not setup")}}}
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 "_Scene1_Unlock":
println("remove ads")
addScene1()
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") }
func paymentQueue(queue: SKPaymentQueue!, removedTransactions transactions: [AnyObject]!) {
println("remove trans") }
override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {
for touch in (touches as! Set<UITouch>) {
let location = touch.locationInNode(self)
if self.nodeAtPoint(location) == self.stopScene1 {
btnAddScene1()
}
