当我在 iPhone6 上运行应用程序时遇到此错误，但在模拟器上确实可以运行。在模拟器中，当我从 AlarmAddEditViewController 转到 RouteTableViewController 时，我在 AppDelegate 上收到 Thread 1: signal SIGABRT 错误。我添加了一个让我选择路线的部分，因此当选择该行时，将执行routeSegue，然后是当我在AppDelegate上收到错误时。我不明白为什么添加到 AlarmAddEditViewController 会弄乱代码。
这是在 iPhone 上运行的结果:

最佳答案
模拟器中的问题是 RouteTableViewController 不是 tableViewControlle，所以我解决了这个问题，现在routeSegue 工作正常。 现在它也可以在 iPhone 上运行。 感谢@Shauket Sheikh 的帮助。
