在SKScene的应用程序购买
是否可以在SKScene中实现应用内购买？ 如果是这样，怎么样？ 我试图使用SKSpriteNode作为'购买'按钮，但没有运气。 我不确定代码是否需要进入SKScene或视图控制器。 我看过大量的教程，但它们似乎都是针对单一视图应用程序，而不是SpriteKit。
首先，把它放在你的游戏场景中，并确保你已经导入了框架'StoreKit'
class GameScene: SKScene, SKPaymentTransactionObserver, SKProductsRequestDelegate {
接下来，您将要将这些行放入您的didmovetoview中。 请记住，在“objects：”之后，您放置的字符串应该是使用iTunes Connect设置的应用内购买标识符。
// Set IAPS
if(SKPaymentQueue.canMakePayments()) {
println("IAP is enabled, loading")
var productID:NSSet = NSSet(objects: "Put IAP id here")
var request: SKProductsRequest = SKProductsRequest(productIdentifiers: productID as Set<NSObject>)
request.delegate = self
request.start()
} else {
println("please enable IAPS")
}
除了任何其他功能，但仍然在游戏场景中，插入这些函数和变量
//In App Purchases
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)
}
}
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 "IAP id here":
//Right here is where you should put the function that you want to execute when your in app purchase is complete
default:
println("IAP not setup")
}
}
var alert = UIAlertView(title: "Thank You", message: "Your purchase(s) were restored. You may have to restart the app before banner ads are removed.", delegate: nil, cancelButtonTitle: "OK")
alert.show()
}
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, .Restored:
println("buy, ok unlock iap here")
println(p.productIdentifier)
let prodID = p.productIdentifier as String
switch prodID {
case "IAP id here":
//Here you should put the function you want to execute when the purchase is complete
var alert = UIAlertView(title: "Thank You", message: "You may have to restart the app before the banner ads are removed.", delegate: nil, cancelButtonTitle: "OK")
alert.show()
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");
}
接下来，您必须命名您需要执行iAP的节点
whateverYourNodeIs.name = "inAppPurchaseNode"
最后，在touchesBegan中做这个
let touch = touches.first as? UITouch
let positionInScene = touch!.locationInNode(self)
let touchedNode = self.nodeAtPoint(positionInScene)
if let name = touchedNode.name {
if name == "inAppPurchaseNode" {
for product in list {
var prodID = product.productIdentifier
if(prodID == "iAp id here") {
p = product
buyProduct() //This is one of the functions we added earlier
break;
}
}
}
}
你也会希望在你的触摸中开始恢复使用不同节点的购买。
if let name = touchedNode.name {
if name == "restore" {
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}
}
