应用程序内购买 – 如何在Swift中使用Xcode 7和SpriteKit修复iOS应用程序中的Restore Purchase？

概述我在 Swift中使用Xcode 7和SpriteKit制作了一个游戏,然后我完成了它.在我将其提交给iTunes Connect之后,Apple拒绝了它并且他们给我发了一条消息,他们说问题出在Restore Purchase上,但是我把它放在购买的同一个按钮中,所以我创建了一个具有两个功能的按钮：  1.进行购买,  2.恢复购买. 当我测试它时,它完美地工作,当用户必须恢复购买时,他们不再付费 我在 Swift中使用Xcode 7和SpriteKit制作了一个游戏,然后我完成了它.在我将其提交给iTunes Connect之后,Apple拒绝了它并且他们给我发了一条消息,他们说问题出在Restore Purchase上,但是我把它放在购买的同一个按钮中,所以我创建了一个具有两个功能的按钮：
 1.进行购买,
 2.恢复购买.

当我测试它时,它完美地工作,当用户必须恢复购买时,他们不再付费.我不知道Apple是否可以接受.或者如果我忘了放些东西,请检查我的代码！

消息是：

From Apple

Missing restore mechanism

We found that your app offers in-app Purchase(s) that can be restored but does not include a “Restore Purchases” feature to allow users to restore the prevIoUsly purchased in-app Purchase(s),as specifIEd in the “Restoring Purchase Products” section of the in-app Purchase Programming GuIDe

“Users restore transactions to maintain access to content they’ve already purchased. For example,when they upgrade to a new phone,they don’t lose all of the items they purchased on the old phone. Include some mechanism in your app to let the user restore their purchases,such as a Restore Purchases button.”

To restore prevIoUsly purchased in-app Purchase products,it would be appropriate to provIDe a “Restore” button and initiate the restore process when the “Restore” button is tapped by the user. Including restore in the purchase button is not a sufficIEnt restore mechanism.

我使用的代码是：

我希望你的贡献对我有所帮助.

解决方法 您可能只需要在屏幕上放置一个按钮供用户按下,然后将其连接到@IBAction func RestorePurchases

我已经为Xcode 7.0,iOS 9.0和Swift 2.0添加了我的默认IAP,使用正确的字符串更改“com.dname.YourApp.removeAds”:)
