我有一个非常有趣的问题。我浏览了这里关于“无法下载应用程序”的所有帖子，但没有看到任何特定于 iPhone 版本的帖子。我有一个已分发的内部应用程序，正在所有 iPhone5 上运行。但是，当我尝试将其安装到 iPhone4s 上时，出现“无法下载应用程序”错误。这告诉我这不是分发文件（.ipa 或配置文件）问题，而是其他问题？我在尝试下载应用程序时搜索了控制台，但没有看到任何错误。我希望有人能在这里看到我没有的东西！
以下是使用 iOS 7.1.2 的 iPhone4S 在尝试安装应用程序时的控制台日志（失败）：

相比之下，这是来自 iPhone5s 7.1.2（有效）的日志：

在这一点上，我会尝试任何事情。我只是不明白有什么不同。我点击了完全相同的 URL，它被定向到相同的 d/l，即使控制台日志几乎完全相同，直到 iPhone4s 出错为止。
有人有什么想法吗？
