我的应用程序发生严重崩溃 -
CALayer position contains NaN: [377.833 nan]
使用以下堆栈 -

查看用户的日志,我发现了一些常见的事情 -
- 所有用户都在一个包含 WKWebView 的视图控制器中
- 所有日志都指出应用程序在崩溃前获得了“applicationWillResignActive”
- 堆栈显示键盘已打开,但我们不必在该视图控制器上打开键盘
- 所有用户都是 iOS 10.3 +
唯一适合的场景是用户在应用程序具有可见的 WKWebView 时收到 iMessage 并强制触摸它以获得快速答案。我们测试了这种情况,然后 BOOOM 应用程序崩溃了。
所以我们找到了崩溃,但我们不知道发生了什么。任何人都面临过这个问题或知道它可能是什么?
谢谢
