這個問題讓我有好幾天的時間。應用內購買和恢復按鈕:單個產品 - 非消耗品
我有一個簡單的應用程序,顯示橫幅和插頁式廣告。
我使用的是單一視圖的應用程序,有主視圖控制器(ViewController.swift
),並建立了另一個視圖控制器(InAppViewController.swift
)來處理一個彈出頁面:
- 允許用戶作出通過應用內購買來移除所有廣告(AdBanners & InterstitialAds);或
- 恢復購買。
當我運行它時,我的代碼沒有錯誤。
應用內購買運行正常,但偶爾我會向iTunes發送兩次登錄請求。
但我的恢復按鈕和關聯的功能似乎是問題。
我已經設置了許多沙箱測試賬戶來測試,而一位沒有購買該應用的新用戶能夠成功恢復購買。這不應該是可能的,所以我在這裏肯定做錯了什麼。
這裏是我的代碼:
主視圖控制器:
// ViewController.swift
import UIKit
import MessageUI
import Social
import iAd
import StoreKit
class ViewController: UIViewController, MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate, ADBannerViewDelegate, ADInterstitialAdDelegate
{
let defaults = NSUserDefaults.standardUserDefaults()
var product_id: NSString?;
override func viewDidLoad() {
product_id = "some.product.id";
super.viewDidLoad()
//Check if product is purchased
if (defaults.boolForKey("purchased")){
print("already purchased")
// Hide or show banner ads is purchased/not purchased.
// Advertising Banner:
self.canDisplayBannerAds = false
}
else if (!defaults.boolForKey("stonerPurchased")){
print("not yet purchased")
// Advertising Banner:
self.canDisplayBannerAds = true
}
此代碼似乎很好地工作。當應用加載時,它可以確定誰支付了刪除廣告和未支付廣告的費用,並且適當地顯示了廣告條幅。
它在第二個視圖控制器(InAppPViewController.swift
)我有問題。
這裏是我的代碼:
二 - 視圖 - 控制器 - InAppViewController.swift:
// InAppPViewController.swift
import UIKit
import StoreKit
import iAd
class InAppPViewController: UIViewController, SKProductsRequestDelegate, SKPaymentTransactionObserver {
let defaults = NSUserDefaults.standardUserDefaults()
var product_id: NSString?;
@IBOutlet weak var unlockAction: UIButton!
@IBOutlet var adBannerView: ADBannerView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func restorePurchases(sender: UIButton) {
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
}
func paymentQueueRestoreCompletedTransactionsFinished(queue: SKPaymentQueue) {
print("Transactions Restored")
let alert = UIAlertView(title: "Thank You", message: "Your purchase(s) were restored.", delegate: nil, cancelButtonTitle: "OK")
alert.show()
}
@IBAction func unlockAction(sender: AnyObject) {
product_id = "some.product.id";
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
//Check if product is purchased
if (defaults.boolForKey("purchased")){
}
else if (!defaults.boolForKey("stonerPurchased")){
print("false")
}
print("About to fetch the products");
// We check that we are allowed to make the purchase.
if (SKPaymentQueue.canMakePayments())
{
let productID:NSSet = NSSet(object: self.product_id!);
let productsRequest:SKProductsRequest = SKProductsRequest(productIdentifiers: productID as! Set<String>);
productsRequest.delegate = self;
productsRequest.start();
print("Fething Products");
}else{
print("can't make purchases");
}
}
func buyProduct(product: SKProduct){
print("Sending the Payment Request to Apple");
let payment = SKPayment(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment);
}
//Delegate Methods for IAP
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
let count : Int = response.products.count
if (count>0) {
let 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: [SKPaymentTransaction]) {
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")
break;
case .Failed:
print("Purchased Failed");
SKPaymentQueue.defaultQueue().finishTransaction(transaction as! SKPaymentTransaction)
break;
case .Restored:
print("Already Purchased");
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
default:
break;
}
}
}
}
}
我要去哪裏錯了?
問題:
- 是我上面的代碼是否正確?
- 我應該修改什麼,爲什麼?
道歉提前,我是新的這個美妙的編碼世界......但愛它的每一分鐘!
