我正在应用程序购买中实现（非消耗型 - 歌曲）。当用户为每首歌曲购买点击购买时，我调用startPurchase 功能。我的歌曲内容通过我的服务器交付。
因为当我购买了一些东西并再次尝试重新购买相同的东西时，它不会被视为购买的恢复。它会进行新的购买。委托方法被多次调用
实际上我的问题是，我点击购买并继续付款，然后购买了该商品。
再次，当我尝试购买相同的商品时，当我点击“确定”时，苹果警报显示为“您已经购买了该商品，点击确定下载”。这不是在SKPaymentTransactionStateRestored下，而是转到SKPaymentTransactionStatePurchased。为什么会发生这种情况? 请帮忙
请帮帮我
