恢复应用内购买Swift

Question

我已在应用中添加了非耗材的应用内购买功能,以移除广告.购买工作正常,恢复我遇到麻烦.我只是不知道该怎么做.

这是我的购买代码:

    func buyNonConsumable(){
    println("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("Fething Products");
    }else{
        println("can't make purchases");
    }
}

// Helper Methods
func buyProduct(product: SKProduct){
    println("Sending the Payment Request to Apple");
    var payment = SKPayment(product: product)
    SKPaymentQueue.defaultQueue().addPayment(payment);
}

func removeTheAds(){

    userDefaults.setBool(true, forKey: "proUser")
    userDefaults.synchronize()
    print("You are a pro User")

    //Code for removing the ads currently
}

// Delegate Methods for IAP
func productsRequest (request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
    println("got the request from Apple")
    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) {
            println(validProduct.localizedTitle)
            println(validProduct.localizedDescription)
            println(validProduct.price)
            buyProduct(validProduct);
        } else {
            println(validProduct.productIdentifier)
        }
    } else {
        println("no product found")
    }
}

func request(request: SKRequest!, didFailWithError error: NSError!) {
    println("There was an error");
}

func paymentQueue(queue: SKPaymentQueue!, updatedTransactions transactions: [AnyObject]!)    {
    println("Received Payment Transaction Response from Apple");

    for transaction:AnyObject in transactions {
        if let trans:SKPaymentTransaction = transaction as? SKPaymentTransaction{
            switch trans.transactionState {
            case .Purchased:
                println("Product Purchased");
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
                removeTheAds()
                break;
            case .Failed:
                println("Purchased Failed");
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
                break;
                // case .Restored:
            default:
                SKPaymentQueue.defaultQueue().finishTransaction(transaction as SKPaymentTransaction)
                break;
            }
        }
    }

}

我该如何处理恢复？我有一个恢复按钮,可以调用这两个,但我现在该怎么办？

    SKPaymentQueue.defaultQueue().addTransactionObserver(self)
    SKPaymentQueue.defaultQueue().restoreCompletedTransactions()

我看到了那个案例.Restored被注释掉但我不知道那里发生了什么.任何帮助将非常感激.

这取决于您在付款恢复时所执行的操作.我在我的应用程序中所做的与我在.Purchased案例中所做的一样 - 我打开了隐藏的功能.在您的应用中,您可以关闭广告.事实上,在我的应用程序中,.Purchased并且.Restored是相同的情况,你可能也可以这样做.这是我的一些代码:

        switch t.transactionState {
        case .Purchased, .Restored:
            // ... turn on the magic ...
        }
