在实际设备上测试中断的购买,下面的第10项不会在同一会话中出现。只有当

  1. 应用程序重新启动
  2. 应用程序转到后台,然后返回前台(对于#2,我猜想这是因为当应用返回前台时,TransactionObserver又被调用了?)

这也谈到了类似的事情:Apple In App Purchase, Interrupted purchase in sandbox

多年来,我一直试图找到解决这个问题的办法。在苹果论坛上,很多人都是如此,也是如此。

参考线程:

  1. https://developer.apple.com/forums/thread/674081
  2. https://developer.apple.com/forums/thread/671492
  3. https://developer.apple.com/forums/thread/685938
  4. Apple In App Purchase, Interrupted purchase in sandbox

根据Apple Docs,中断的事务应该发送失败,然后在用户同意T&C/继续中断购买后购买(但实际上似乎没有发生-参考上面的链接线程)

这就是我现在的解决方案。这并不完全理想,但鉴于当时的情况,这是最好的(我发现)。请参阅链接3,其中用户观察到调用restoreCompletedTransactions()实际上能够让事务观察者处理(已完成)中断的事务。这样做,用户不需要关闭(背景),然后重新打开应用程序。(请注意,我尝试了各种方法再次调用事务观察者,但都没有帮助)

这是我的解决方案。

        print("\(FormatDisplay.datems(Date())) [IAP] -- Calling SKPaymentQ.FinishTransaction")
        
        SKPaymentQueue.default().finishTransaction(transaction)
        purchaseCompletionHandler?(true)
    }

这是purchaseIapFailed()的内容,一旦用户按下OK按钮,就调用restoreCompletedPurchases()

代码语言:javascript
运行
复制
static func presentIapFailed(title: String, message: String, errMsg: String) {
    let root = UIApplication.shared.keyWindow?.rootViewController
    let alertController = UIAlertController(title: title,
                                            message: message,
                                            preferredStyle: .alert)
    
    alertController.addAction(UIAlertAction(title: "OK", style: .cancel, handler: {( action: UIAlertAction ) in
        print("    displayAlert - presentIapFailed: \(errMsg) - OK Pressed")
        
        // Call RestorePurchases to force replaying the transaction list.
        Medals.store.restorePurchases()
    }))
    
    root?.present(alertController, animated: true, completion: nil)
}

一旦事务被“恢复”,它将继续触发后续代码来跟踪购买,发送一个通知(购买完成/成功),然后弹出一条警告消息,通知用户购买成功并已贷记消耗品。
