swift - 第二次启动后在设备上运行时崩溃

Question

我不是工程师，所以对我的简单天气应用程序中的崩溃感到有点不知所措，该应用程序并排显示摄氏温度和华氏温度。我仅更新到 iOS 13 SDK 并更改了夜间模式的一些颜色。

应用程序在模拟器中运行良好，并且在从 Xcode 启动时在设备上也可以正常启动。但是，当硬关闭应用程序并在设备上重新启动时，我会遇到以下崩溃。我不知道如何调试崩溃，因此非常感谢您的帮助!

Answer 1

我遇到了同样的崩溃问题，然后我解决了它。我希望您分享以下我的解决方案，但这可能取决于您的应用程序。希望对您有帮助。

在 this thread在苹果论坛上，爱斯基摩人的评论救了我(顺便说一句，爱斯基摩人总是在论坛上帮助我)。根据评论，我知道我必须在控制台应用程序中检查设备的控制台日志，然后我发现了以下日志。

*** Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named MKMapView because no class named MKMapView was found; the class needs to be defined in source code or linked in from a library (ensure the class is part of the correct target)'

感谢日志的指示，我发现将 Maps.framework 与我的应用程序二进制文件链接时出现问题。因此我将 Maps.framework 放入 Xcode 中的“框架、库和嵌入式内容”中。

结果，我可以解决崩溃问题!(这很奇怪。)我认为这个问题应该由 Xcode 11 拥有，并且需要由 Xcode 修复。
