使用StoreKit的未记录的NSURLErrorDomain错误代码（-1001，-1003

Question

我正在编写与StoreKit相关的代码，当我尝试将购买添加到队列时，我得到了一些相当麻烦的错误代码。到目前为止，我遇到了错误代码-1003和-1004，但在Internet上找不到任何有关这些代码的信息。运行产品请求会返回有效的产品编号，因此我不知道为什么调用[[SKPaymentQueue defaultQueue] addPayment:aPayment];此未记录问题会失败。相同的代码也可以在没有错误的情况下在一个设备上运行，而在另一台设备上则没有错误。到目前为止，我的问题尚未得到解答：这些代码是什么意思？我该如何缓解这个问题？为什么发生这种情况是因为尝试购买而不是出于产品请求？我已经完成的故障排除包括重新生成签名证书和配置文件，更改WiFi网络，清理和构建并重新安装所有相关软件和组件，而这些事情单独或一起都无助于解决问题。编辑：在Apple开发人员论坛上找到了有关此问题的讨论，但是Apple没人回应：https : //devforums.apple.com/thread/107121? tstart =75（需要iOS开发人员帐户才能查看）编辑：今天，我遇到了错误代码-1001，将其添加到此莫名其妙和间歇性问题列表中。我仍然找不到苹果的问责制。编辑：我怀疑这些错误代码是随机生成的，实际上仅表示沙盒已关闭。还有其他人遇到这个问题吗？
