正如标题所示,如果没有打开互联网连接/飞行模式,我的应用程序在运行时会立即崩溃。问题是,当我设置断点时,它甚至没有到达我的任何代码。没有调用任何 viewDidLoad 甚至 AppDelegate 函数,并且错误消息似乎与没有网络连接无关:

2019-03-21 10:30:20.193955-0500 AppName[98957:977030] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle <bundleFilePath> (loaded)' with name 'BYZ-38-t0r-view-8bC-Xf-vdC''

(出于隐私考虑,我显然在其中插入了一些虚假值)

调用堆栈:

我真的不知道它会是什么。尝试在 [UIViewController _loadViewFromNibNamed:bundle:] 设置符号断点,但这并没有真正提供任何有用的见解。希望有人能帮忙。我还应该提到我在 AppDelegate 中所做的唯一一件事就是实例化 firebase。

最佳答案

reddit 上的一个乐于助人的人帮我解决了这个问题。没有意识到,但我的初始 View Controller 上有一个 init() 函数,最后一个人制作的函数检查了互联网连接,如果没有,则重定向到另一个页面。
