是否可以在内实施应用内购买SKScene?如果是这样,怎么办?我正在尝试将SKSpriteNode“购买”按钮用作运气不好的按钮。我不确定代码是否需要放入SKScene或视图控制器中。我看过大量的教程,但它们似乎都针对单视图应用程序,而不是SpriteKit。
SKScene
SKSpriteNode
首先,将其放入游戏场景行中,并确保已导入框架“ StoreKit”
class GameScene: SKScene, SKPaymentTransactionObserver, SKProductsRequestDelegate {
接下来,您想将这些行放到didmovetoview中。请记住,在“对象:”之后,您输入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") }
在任何其他功能之外,但仍在游戏场景内,插入这些功能和变量
//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,您必须命名执行iAP所需的节点
whateverYourNodeIs.name = "inAppPurchaseNode"
最后,轻而易举地做到这一点
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; } } } }
您还将希望与此同时开始使用其他节点恢复购买。
if let name = touchedNode.name { if name == "restore" { SKPaymentQueue.defaultQueue().restoreCompletedTransactions() SKPaymentQueue.defaultQueue().addTransactionObserver(self) } }
