InApp购买不完整支付

Question

我已经做了一个 IAP 的演示，并且我已经在苹果帐户中注册了我的演示应用程序，我还添加了产品信息、描述、应用程序 ID、标题、价格层、沙盒帐户，用于测试支付过程为演示中描述。我现在面临两个问题：-

a) 就像弹出窗口第一次要求输入 apple-id/password 一样，我已经提供了这两个值。它将显示我是否要确认我的付款，并在该弹出窗口中显示产品名称和产品价格。单击“确定”后，我什至没有收到来自 Apple 的邮件，所以我如何证明我是否已成功付款。

b) 我还想在购买产品时更改我的登录 ID。但是每次默认情况下都会使用我以前的 id 并向我显示密码框，仅用于输入密码。如何重置此设置？就像我尝试重置模拟器并再次在 iTunes 中的苹果空调中添加新产品一样。因此，如果有人有任何想法，请随时提供帮助。在下面分享我的代码：-

    -(void)fetchAvailableProducts{
        if ([SKPaymentQueue canMakePayments])
        {
            SKProductsRequest *request = [[SKProductsRequest alloc]
                                          initWithProductIdentifiers:
                                          [NSSet setWithObject:kTutorialPointProductID]];
            request.delegate = self;

            [request start];
        }
        else

            NSLog(@"Please enable In App Purchase in Settings") ;
    }

    -(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
    {

        NSArray *products = response.products;
            if (products.count != 0)
        {
            _product = products[0];
            NSLog(@"procudt info is %@",_product.localizedTitle);

    //        _buyButton.enabled = YES;
    //        _productTitle.text = _product.localizedTitle;
    //        _productDescription.text = _product.localizedDescription;
            [self purchaseProducts];
        } else {
            //_productTitle.text = @"Product not found";
        }

        products = response.invalidProductIdentifiers;

        for (SKProduct *product in products)
        {
            NSLog(@"Product not found: %@", product);
        }
    }
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchased:
               [[SKPaymentQueue defaultQueue]
                 finishTransaction:transaction];
                 NSLog(@"Transaction complete");
                break;

            case SKPaymentTransactionStateFailed:
                NSLog(@"Transaction Failed");
                [[SKPaymentQueue defaultQueue]
                 finishTransaction:transaction];
                break;

            default:
                break;
        }
    }
}

首先，我只是使用我的产品 ID 获取我的产品，我在委托方法中得到响应，如果计数 >0，则将调用“purchaseProducts”方法。但问题是我的委托方法没有被调用，在我点击“确定”购买产品后什么也没有发生。请分享您的想法。

你好，按照给定的步骤，希望它有效-

首先检查用户是否可以付款-

-(void)checkForPayement{

//First check if user can make payments
if (![SKPaymentQueue canMakePayments]) {
    // Show the error that user can't make payments.
}else{
    // Make the product request on App Store
    SKProductsRequest *productRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:IAP_PRODUCT_ID]];   // IAP_PRODUCT_ID is the product id which you got when you register the in-app-purchase
    productRequest.delegate = self;
    [productRequest start];
  }
}

如果产品可用，您将通过以下方法获得响应-

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
if (response.products.count > 0) {
    SKProduct *validProduct = [response.products objectAtIndex:0];
    [self purchase:validProduct];
} else {
    // Product is not available so please cross check about the IAP_PRODUCT_ID
  }
}

如果请求失败，你会在下面的方法中得到回调-

-(void)request:(SKRequest *)request didFailWithError:(NSError *)error{  
    // Check here for the error
 }

开始购买

- (void)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

}

您将在给定的方法中获得回调，您可以检查交易的状态-

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions{
for (SKPaymentTransaction *transaction in transactions) {
    switch (transaction.transactionState) {
        case SKPaymentTransactionStatePurchasing:
            DDLogVerbose(@"Purchasing");
            break;

        case SKPaymentTransactionStateFailed:
            if (transaction.error.code == SKErrorPaymentCancelled) {
                // User has cancelled the transaction
            }
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;

        case SKPaymentTransactionStateRestored:

            DDLogVerbose(@"Restored");
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;

        case SKPaymentTransactionStatePurchased:
        {
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
           //  Payment has been done and you should provide the purchased content or you may verify the receipt also
            DDLogVerbose(@"Purchased");

        }
            break;

        default:
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
    }
 }
}

如果您想要更多安全性，也可以Verify receipt from app store

解决您的问题

一个。在沙盒环境中测试应用内购买时，您不会收到任何确认付款的邮件，您可以在 Storekit updatedTransactions 委托方法中查看您的付款状态。在沙盒环境下不会扣除余额。输入沙盒账户信息后，还要检查iTunes账户是否可以登录？如果没有，您的 id 可能未经过验证，因此请验证您的 id。

b.在尝试应用内购买之前，只需从“设置”->“iTunes 和 App Store”中注销 Apple id。点击apple id，然后点击注销。并且当您启动应用内购买时，请输入沙盒帐户凭据，并且不要在实际生产环境中登录沙盒帐户，因为它可能会使您的沙盒帐户失效。
