所以我知道问题出在带有 IAP 的 ViewController 上，但不确定如何解决。
我添加SKPaymentQueue.defaultQueue().addTransactionObserver(self)并viewDidLoad有班级的代表；SKProductsRequestDelegate, SKPaymentTransactionObserver.
我使用这些方法来执行购买交易、恢复任何购买并进行非消耗性购买所需的任何更改。
但无论用户做什么，加载IAPViewController应用程序后都会不断提示用户登录。它主要是当用户退出应用程序然后重新打开它时。
我尝试SKPaymentQueue.defaultQueue().removeTransactionObserver(self)在关闭视图时添加，但这似乎不起作用。
有没有人有什么建议 ？？由于这个错误，我不得不将我的应用程序从审查中撤出:(
这是完整的代码；

var productIDs: Array<String!> = []
var productsArray: Array<SKProduct!> = []

productIDs.append("com.COMPANY.NAME.BUY02")

productIDs.append("com.COMPANY.NAME.BUY04")

SKPaymentQueue.defaultQueue().addTransactionObserver(self)
