ios - WebThread JavaScriptCore 崩溃——这个崩溃报告意味着什么

转载作者：可可西里更新时间：2023-11-01 04:38:18

我需要来自测试用户的帮助来理解这个崩溃日志。我没有在我的应用程序中编写任何 JavaScriptCore 相关代码。

我仍然不知道如何重现这次崩溃。关于这个问题的任何见解都将有助于我找到这个问题。

谢谢，

附言我的应用程序正在使用 Admob 中介。不知道跟这个有没有关系。

最佳答案

这次崩溃是 bug in WebKit 的结果.这是fixed at 06/05/15 . iOS 9 于 2015 年 9 月 9 日发布，所以这个错误很可能已经在上一个 iOS 版本中得到修复。尽管它仍然会影响 iOS 8，并且没有直接的解决方法。
