正如标题所说，如果没有互联网连接/飞机模式，我的应用程序会在运行时立即崩溃。问题是，当我设置断点时，它甚至不能用于我的任何代码。不会调用单个viewDidLoad甚至AppDelegate函数，并且错误消息似乎与没有网络连接有关：
2019-03-21 10：30：20.193955-0500 AppName [98957：977030] ***由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'无法在bundle中加载NIB：'NSBundle <bundleFilePath>（已加载）'名字'BYZ-38-t0r-view-8bC-Xf-vdC''
（我显然在他们的隐私中插入了一些假值）
调用堆栈：

我真的不知道它可能是什么。尝试在[UIViewController _loadViewFromNibNamed:bundle:]设置一个符号断点，但这并没有给出任何有用的见解。希望有人能提供帮助。我还应该提到我在AppDelegate做的唯一一件事就是实例化firebase。
在reddit有用的家伙为我找到了它。没有意识到，但我的初始视图控制器上有一个init（）函数，最后一个人检查了互联网连接并重定向到另一个页面，如果没有。
