我收到“此应用内购买已被购买，它将免费恢复”但未调用委托 updatedTransactions 并且没有任何反应，IAP 不执行。
我已经实现了恢复购买，它工作正常，但是我如何防止用户再次购买非消耗品？为什么不调用委托 updatedTransactions(SKPaymentTransactionState.Restored)？
即使在删除并重新安装应用程序后进行购买也会显示此弹出窗口。
这是我的代码。如果我做错了什么，请告诉我。谢谢
func makePaymentForProduct(product:SKProduct){
let payment = SKPayment.init(product: product)
SKPaymentQueue.defaultQueue().addPayment(payment)
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}
func restorePurchases(){
SKPaymentQueue.defaultQueue().restoreCompletedTransactions()
SKPaymentQueue.defaultQueue().addTransactionObserver(self)
}
//MARK: SKProductsRequestDelegate
func productsRequest(request: SKProductsRequest, didReceiveResponse response: SKProductsResponse) {
self.delegate?.didGetProducts(response.products)

self.delegate?.purchaseFailed(error.localizedDescription)

case SKPaymentTransactionState.Restored:
self.restoreTransaction(transaction)

case SKPaymentTransactionState.Failed:
self.failedTransaction(transaction)
