请指导问题是什么？
编辑： 失败并出现错误被调用。＆＃34;无法加载产品列表。＆＃34;
答案 0 :(得分：0)
确保您已退出设备上的所有生产iTunes帐户。
我在测试手机上收到此错误，该手机已使用我的实际iTunes帐户登录。 您无法使用生产iTunes帐户测试应用，因此出现错误。我只是希望Apple提供更好的错误，以避免这种猜测......
解决方案是创建测试用户帐户，如果您没有。使用该帐户测试应用内购买。
注意：如果您没有收到产品，请确保您在发送与itunes上的产品标识符完全匹配的请求时使用的是产品标识符。
另一个愚蠢的原因，我们在模拟器上运行时会遇到这个错误。检查是否
您的应用正在模拟器中运行，该模拟器不支持In-App 购买

退出iTunes＆amp; iCloud帐户我重置了我的iOS设备＆amp;在应用程序购买工作。虽然我不知道为什么。
您无需登录iOS设备即可从应用内购买产品。要购买产品，我们必须登录设备。
