Question

我正在使用已弃用的API，我想更新我的代码以使用非depcreated代码。

所以我的大问题是如何获得回复列表？

cat input.txt | ./calculate.sh > output.txt

aryProductIDs在（id）init

下定义

- (void) buyFeature:(NSString*) featureId
{
//    SKProduct *myProduct;
    if ([SKPaymentQueue canMakePayments])
    {
        SKPayment *payment = [SKPayment paymentWithProductIdentifier:featureId];
//        SKPayment *payment = [SKPayment paymentWithProduct:myProduct];
        [[SKPaymentQueue defaultQueue] addPayment:payment];
    }
    else
    {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"purchaseDone" object:nil];

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Warning" message:@"You are not authorized to purchase from AppStore"
                                                       delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
    }
}

- (void) purchase: (int) productIndex {
    [self buyFeature: [aryProductIDs objectAtIndex: productIndex]];
}

我不确定myProduct的用途（类型SKProduct）。

我见过很多使用NSSet代替NSMutableArray的例子。不确定我是否需要更改

首先，您需要获取所有产品的产品信息：

<%# app/views/users/_modal_wrapping.html.erb %>
<div id='modal'>
  <%= simple_form_for @user do |f| %>
    <%= yield f %>
  <% end %>
</div>

您将获得委托回调。您可能希望使用响应创建字典：

NSSet *productsToRequest = [NSSet setWithArray:aryProductIDs];
SKProductsRequest *request= [[SKProductsRequest alloc] initWithProductIdentifiers:productsToRequest];
request.delegate = self;
[request start];

您可能希望查看回复并检查是否还有- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { NSMutableDictionary *dict = [NSMutableDictionary dictionary]; for (SKProduct *product in response.products) { dict[product.productIdentifier] = product; } self.products = dict; }，但这是基本想法。

我如何为SKPaymentQueue使用非弃用的API？
