我正在学习苹果提供的应用内购买。所以我按照这个教程进行操作： http://www.appcoda.com/in-app-purchase-tutorial/
我按照这个教程中的所有步骤进行了操作。首先，我创建了一个应用程序ID，然后使用该应用程序ID在iTunes中创建一个应用程序。然后我创建了两个产品ID为“com.outlines.feature1”和“com.outlines.feature2”的应用内购买，它们都是可消耗品。其余的代码我只需按照上述教程的步骤进行操作。
import UIKit
import StoreKit
protocol IAPurchaceViewControllerDelegate {
func didBuyColorsCollection(collectionIndex: Int)
}
class IAPurchaceViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, SKProductsRequestDelegate, SKPaymentTransactionObserver {
@IBOutlet weak var tblProducts: UITableView!
var delegate: IAPurchaceViewControllerDelegate!
var selectedProductIndex: Int!
var transactionInProgress = false
let productIdentifiers = NSSet(array: ["com.outlines.feature1", "com.outlines.feature2"])
var product: SKProduct?
var productsArray = Array<SKProduct>()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
tblProducts.delegate = self
tblProducts.dataSource = self
//checks whether the In-App feature is activated or not
requestProductInfo()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}
func requestProductInfo(){
if SKPaymentQueue.canMakePayments() {
let request = SKProductsRequest(productIdentifiers:
productIdentifiers as! Set<String>)
print("This is the request to be sent \(request)")
request.delegate = self
request.start()//calls productsRequest() function
}
else {
print("Cannot perform In App Purchases.")
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK: IBAction method implementation
@IBAction func dismiss(sender: AnyObject) {
dismissViewControllerAnimated(true, completion: nil)
}
// MARK: UITableView method implementation
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return productsArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("idCellProduct", forIndexPath: indexPath) as UITableViewCell
let product = productsArray[indexPath.row]
cell.textLabel?.text = product.localizedTitle
cell.detailTextLabel?.text = product.localizedDescription
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
selectedProductIndex = indexPath.row
showActions()
tableView.cellForRowAtIndexPath(indexPath)?.selected = false
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 80.0
}

func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
if response.products.count != 0 {
for product in response.products {
productsArray.append(product as SKProduct)
}
tblProducts.reloadData()
}
else {
print("There are no products.")
}
if response.invalidProductIdentifiers.count != 0 {
print("Invalid "+response.invalidProductIdentifiers.description)
}
}
func showActions() {
if transactionInProgress {
return
}
let actionSheetController = UIAlertController(title: "IAPDemo", message: "What do you want to do?", preferredStyle: UIAlertControllerStyle.ActionSheet)
let buyAction = UIAlertAction(title: "Buy", style: UIAlertActionStyle.Default) { (action) -> Void in
let payment = SKPayment(product: self.productsArray[self.selectedProductIndex] as SKProduct)
SKPaymentQueue.defaultQueue().addPayment(payment)
self.transactionInProgress = true
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (action) -> Void in
}
actionSheetController.addAction(buyAction)
actionSheetController.addAction(cancelAction)
presentViewController(actionSheetController, animated: true, completion: nil)
}
func paymentQueue(queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
for transaction in transactions as [SKPaymentTransaction] {
switch transaction.transactionState {
case SKPaymentTransactionState.Purchased:
print("Transaction completed successfully.")
SKPaymentQueue.defaultQueue().finishTransaction(transaction)
transactionInProgress = false
delegate.didBuyColorsCollection(selectedProductIndex)
case SKPaymentTransactionState.Failed:
print("Transaction Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction)
transactionInProgress = false
default:
print(transaction.transactionState.rawValue)
}
}
}
}
没有错误，但是在iPhone上运行时，控制台会显示：
This is the request to be sent <SKProductsRequest: 0x15d86210>
There are no products.
Invalid ["com.outlines.feature1", "com.outlines.feature2"]
控制台没有显示任何产品，但是我已经在我的iTunes id中添加了两个应用内购买功能。这里是截图：
有人能告诉我我在做什么错了吗？
