azure - iOS xamarin - 在应用内购买时首次启动时崩溃

Question

我们在 xamarin 应用程序中使用了 Azure SDK。当我们在我们的应用程序中使用 Azure 使用谷歌或 Facebook 登录，然后使用应用程序内购买进行订阅时，应用程序在 iOS 中崩溃。

一旦应用内购买对话框打开，应用就会崩溃。

此外，在应用安装后第一次订阅时它会崩溃。然后一切正常。

请查看下面的详细错误日志。

使用包的版本详细信息如下，

"Microsoft.Azure.Mobile.Client" 版本="4.1.1"

"Plugin.InAppBilling" 版本="2.0.0"

“Xamarin.Forms”版本="3.5.0.129452"

var billing = CrossInAppBilling.Current；var purchase = await billing.PurchaseAsync("ProductId here", ItemType.Subscription, "devId");
