objective-c - 在 NSKeyValueCoding 中崩溃 IOS 13 和 Xcode 11

问题描述

在运行 IOS 13.5 的 iPhone 和 iPad 上使用几分钟后，该应用程序崩溃了几次。然而，它在运行 IOS 12 时没有问题。我分析了设备的崩溃日志报告，无论是 iPhone 还是 iPad，它们都在如下所示的崩溃日志中显示了相同的崩溃：

Exception Type:  EXC_CRASH (SIGABRT)

但我仍然对这个问题感到困惑。可能是调用了一个不存在的方法，归结为key-value-coding，但是在Xcode中编译没有发现任何错误。所以我想知道如何解决它。
