私のアプリケーションでIn App Purchaseを使用していますが、テストしているときに問題があります。私は4つの消耗品を持っています。 tableviewに示す商品に関する情報商品を購入するためにボタンをクリックすると、取引の状態がSKPaymentTransactionStateFailedでupdatedTransactionになりますが、transaction.error localizedFailureReasonは常にnullです。 1回の取引が2回更新されたことがわかりました（updatedTransactionの機能取引で同じtransactionIdentifierがある場合、取引の状態はSKPaymentTransactionStatePurchasedです）。その商品は2回購入されましたか？iPhone In App購入の問題
だから私はどこに問題があるか分かりません。私を助けてください。私が作る関数didFinishLaunchingWithOptionsでAppDelegateで

こと：私はアプリ内購入で管理するために、そのクラスを使用
：購入ビューで[InAppPurchaseManager sharedInstance];
私は私が作るボタンをクリックしてください
UpgradeProduct *selectedProduct = [self.faxProducts objectAtIndex:[purchaseButton.identifier intValue]];
if (selectedProduct) {
[[InAppPurchaseManager sharedInstance] purchaseUpgrade:selectedProduct.productID];
}
あなたは私の時間を節約しました。たくさんありがとうございます... – girish
