大佬教程收集整理的这篇文章主要介绍了使用单一产品在Swift中进行应用内购买，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
步骤0：在您的iTunes Connect帐户中，创建一个应用内购买。
对于单次购买，请使用以下方法：
进口
import StoreKit
符合StoreKit委托
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;
}
}
}
}
import StoreKit
class YOURVIEWController:UIVIEwController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
let product_ID: Nsstring = "com.some.inappID" // <!-- Change it to your inapp ID
在您的vIEwDIDLoad添加中
overrIDe func vIEwDIDLoad() {
super.vIEwDIDLoad()
SKPaymentQueue.default().add(self)
在您的购买按钮操作中
@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");
}
}
在“还原”按钮中
// MARK: - Restore In App Purchase
@IBAction func restoreAction(_ sender: UIbutton) {
if (SKPaymentQueue.canMakePayments()) {
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().restoreCompletedTransactions()
} else {
// show error
}
}
添加代表：
// SKProductRequest Delegate
func productsRequest(_ request: SKProductsRequest, dIDReceive response: SKProductsResponse) {
print(response.products)
let count : Int = response.products.count
if (count>0) {
let valIDProduct: SKProduct = response.products[0] as SKProduct
if (valIDProduct.productIDentifIEr == self.product_ID as String) {
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]) {
for transaction:AnyObject in transactions {
if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
self.dismisspurchaseBtn.isEnabled = true
self.restorePurchaseBtn.isEnabled = true
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
}
是否有一种简单的方法可以针对单个产品快速实施应用内购买？
我想要一个可以触发应用内购买的按钮，例如[广告删除]或[解锁高级内容]
我不明白它的全部逻辑。
我正在尝试从[Techotopia] http://www.techotopia.com/index.php/An_iOS_7_In-
App_Purchase_Tutorial中阅读并翻译此教程
但这是我第一次使用StoreKit框架，也是使用Swift。
我只想了解Swift StoreKit框架内应用内购买交易的逻辑。
谢谢！
