昨天我的 iPhone 应用程序运行得很好。今天我遇到了这个崩溃:
*** 由于未捕获的异常“NSGenericException”而终止应用程序，原因:“此编码器要求从 initWithCoder 返回替换的对象:”
当使用 Storyboard转场从一个 View 转到另一个 View 时会发生这种情况(也以编程方式尝试过)。目标 View Controller 是一个 UITableViewController ，这没什么奇怪的。我已经回滚了我的代码以检查是否有任何更改导致此崩溃，但什么也没有。我所做的最新测试版本仍然可以使用相同的代码正常工作。
有人知道可能出了什么问题吗？我没有主意了。

最佳答案
我注意到 Xcode 在工作应用程序和崩溃应用程序之间的时间内进行了更新。我从 Xcode 10.2 回滚到 10.1，现在崩溃消失了，应用程序工作正常。
回滚是一种解决方法，而不是解决办法。
问题出在我使用的 pod(称为 Inputmask)中，同时问题已在 pod 中修复，现在 Xcode 10.2 一切正常。
