ios - 应用内购买不起作用，显示无产品

Question

我正在学习 Apple 提供的应用内购买。所以我正在关注本教程: http://www.appcoda.com/in-app-purchase-tutorial/

我遵循了本教程中的所有步骤。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 中创建了一个应用程序。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，它们都是消耗品。 其余代码我只是按照上述教程中的步骤操作

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，但是当我在 iPhone 上运行它时，控制台显示:

This is the request to be sent <SKProductsRequest: 0x15d86210>
There are no products.
Invalid ["com.outlines.feature1", "com.outlines.feature2"]

控制台未显示任何产品，但我在我的 iTunes id 中添加了两个应用程序内功能。这是屏幕截图:

谁能告诉我我做错了什么？？

我终于解决了。代码和应用内购买制作过程都没有错误。之前提到的上传快照的解决方案也不是问题所在。

问题是协议(protocol)、税收和烘焙中的契约(Contract)。教程中没有提到，但我们需要在iTunes中的Agreements, Tax and Banking中完成一份契约(Contract)，我没有做过。填写契约(Contract)表格后，将对其进行处理。然后契约(Contract)将生效，然后在 iTunes 中创建的应用内购买将被识别。
