Swift)でアプリ内購入を実装する簡単な方法はありますか?
[広告削除]や[ロック解除プレミアムコンテンツ]などのアプリ内購入をトリガーするボタンが欲しい
私はそれの完全な論理を理解することができません。
[Techotopia]からこのチュートリアルに従って翻訳しようとしています http://www.techotopia.com/index.php/An_iOS_7_In-App_Purchase_Tutorial
しかし、StoreKitフレームワークとSwiftは初めてです。
Swift StoreKit Frameworkを使用したアプリ内購入トランザクションのロジックを知りたいだけです。
ありがとう!
ステップ0:iTunes Connectアカウントで、アプリ内購入を作成します。
シングル購入の場合は、次の方法を使用します。
import StoreKit
class YOURViewController: UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
let defaults = NSUserDefaults.standardUserDefaults()
var product_id: NSString?
override func viewDidLoad() {
product_id = "YOUR_PRODUCT_ID"
super.viewDidLoad()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
//Check if product is purchased
if (defaults.boolForKey("purchased")){
// Hide a view or show content depends on your requirement
overlayView.hidden = true
} else if (!defaults.boolForKey("stonerPurchased")) {
print("false")
}
}
@IBAction func unlockAction(sender: AnyObject) {
print("About to fetch the products")
// We check that we are allow to make the purchase.
if (SKPaymentQueue.canMakePayments()) {
var productID:NSSet = NSSet(object: self.product_id!);
var productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID);
productsRequest.delegate = self;
productsRequest.start();
println("Fetching Products");
} else {
print("can't make purchases");
}
}
func buyProduct(product: SKProduct) {
println("Sending the Payment Request to Apple");
var payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment);
}
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
var count : Int = response.products.count
if (count>0) {
var validProducts = response.products
var validProduct: SKProduct = response.products[0] as SKProduct
if (validProduct.productIdentifier == self.product_id) {
print(validProduct.localizedTitle)
print(validProduct.localizedDescription)
print(validProduct.price)
buyProduct(validProduct);
} else {
print(validProduct.productIdentifier)
}
} else {
print("nothing")
}
}
func request(request: SKRequest!, didFailWithError error: NSError!) {
print("Error Fetching product information");
}
func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!) {
print("Received Payment Transaction Response from Apple");
for transaction:AnyObject in transactions {
if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
switch trans.transactionState {
case .Purchased:
print("Product Purchased");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
defaults.setBool(true , forKey: "purchased")
overlayView.hidden = true
break;
case .Failed:
print("Purchased Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
break;
case .Restored:
print("Already Purchased");
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
default:
break;
}
}
}
}
Swift> 3.
import StoreKit
class YOURVIEWController:UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
let product_id: NSString = "com.some.inappid" // <!-- Change it to your inapp id
viewDidLoad
に追加
override func viewDidLoad() {
super.viewDidLoad()
SKPaymentQueue.default().add(self)
購入ボタンアクションで
@IBAction func buyNowAction(_ sender: UIButton) {
if (SKPaymentQueue.canMakePayments()) {
let productID:NSSet = NSSet(array: [self.product_id as NSString]);
let productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>);
productsRequest.delegate = self;
productsRequest.start();
print("Fetching Products");
} else {
print("can't make purchases");
}
}
復元ボタンアクション
// MARK: - Restore In App Purchase
@IBAction func restoreAction(_ sender: UIButton) {
if (SKPaymentQueue.canMakePayments()) {
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().restoreCompletedTransactions()
} else {
// show error
}
}
代理人を追加:
// SKProductRequest Delegate
func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse) {

print(validProduct.localizedTitle)
print(validProduct.localizedDescription)
print(validProduct.price)
self.buyProduct(product: validProduct)
} else {
print(validProduct.productIdentifier)
}
} else {
print("nothing")
}
}
func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {

self.buyNowBtn.isEnabled = true
switch trans.transactionState {
case .purchased:
print("Product Purchased")
//Do unlocking etc stuff here in case of new purchase
SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
break;
case .failed:
print("Purchased Failed");
SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
break;
case .restored:
print("Already Purchased")
//Do unlocking etc stuff here in case of restor
SKPaymentQueue.default().finishTransaction(transaction as! SKPaymentTransaction)
default:
break;
}
}
}
}
//If an error occurs, the code will go to this function
func paymentQueue(_ queue: SKPaymentQueue, restoreCompletedTransactionsFailedWithError error: Error) {
// Show some alert
}
