Ios 当'；假'；连接可用

我正在开发一个应用程序，允许用户使用STTwitter库查看公共twitter提要（见下面的代码）

当我关闭笔记本电脑上的wifi时，应用程序进入错误块，一切正常，用户会收到一条警报，表示连接不可用

但是，由于我使用的是wifi热点（如bt openzone），需要登录，当我重新打开wifi并且不登录（意味着我无法访问互联网）时，应用程序认为它可以访问互联网，并试图访问twitter api，然后崩溃

我已经尝试使用“可达性”来确定天气是否可用互联网（见下文）

然而，这并没有起作用

苹果会因为这样的原因拒绝我的应用程序吗

有没有办法阻止这种情况发生

谢谢你的帮助：）

也许不会，但它应该。您正在证明一个正在崩溃的应用程序，并且您知道这一点。至于wifihotspot，我发现很难相信您不能使用可达性来实现它，因为这段代码出现在许多地方

，及

您可以进行另一项测试，而不是上述解决方案：

我确认这是STTwitter库中的崩溃

我刚推了一个补丁：

如果您遇到任何进一步的问题，请告诉我。

谢谢您的快速回复。我不打算按原样提交。至于这些帖子，我已经看过并尝试过了，但都出现了相同的问题。STTwitter库不应该在网络条件发生变化时崩溃。如果您发布崩溃堆栈跟踪，我们将能够告诉您要修复的内容。@nst请参阅堆栈跟踪
