我正在努力将应用内购买添加到我的应用中.
我能够接收productsRequest:didReceiveResponse方法，并接收产品array.
我的问题是在SKPaymentQueue的基础上加SKPayment.将产品添加到队列后，在paymentQueue:updatedTransactions方法中，事务的状态始终为SKPaymentTransactionStateFailed.
我记录"transaction.error"，它返回的结果是:error
我已经在设置应用程序中注销了store ，但在try 在我的应用程序中购买产品后，它从未要求我使用测试帐户登录.它只是因为上面的错误而失败.
我假设您已经完成了标准的健全性判断:双重判断您的代码，确认您的产品ID，将您的代码与应用内购买编程指南进行比较，等等.
This may be ridiculous, but -- if you're certain your code is correct -- do a hard reset (full wipe) of your iPod (Settings => General => Reset => Erase All Content and Settings). I puzzled over this exact problem for hours -- it turned out my code was correct and the hard reset was the solution.
