ios - Swift / App Store：应用内购买问题

Question

我的应用程序有问题。在 ios 12,4 iphone 5s 上，我的应用内购买非常好用。但是当我在 Apple Store 发送二进制文件时，我得到了一个回报：“我们注意到您的应用程序仍然没有在应用程序中显示应用内购买产品的购买按钮。”。购买按钮仅在付款处理已准备就绪。在家里大约 2 到 3 秒。但是对于他们显然它根本不起作用......这是我的商店处理所有事情的完整代码。我指定使用我的 iphone 我设法拥有购买窗口并在沙盒中购买集成购买。

查看我个人一周前使用的这个 Gist，并通过了 AppStore 对 In-App Purchase 流程的审查。

Swift 5中的IAP服务：

https://gist.github.com/egzonpllana/abd6d385bb45b1e329fe85a624ee531f

您可以调用IAPService.shared.getProducts()AppDelegate 方法：didFinishLaunchingWithOptions要在任何视图控制器中从 StoreKit 中准备好所有产品，只需检查IAPService.shared.products.count.

或者在 viewDidLoad 中调用您的特定视图控制器并通过以下方式监听更改：IAPService.shared.didFinishRetrievingProducts = { [ weak self ] in ... }
