ios – UIWebView WebCore TimerBase仅在11.3(15E216)上崩溃：SIGTRAP WebCore _ZN7WebCore9TimerBaseD2Ev

iOS 前端之家
前端之家收集整理的这篇文章主要介绍了ios – UIWebView WebCore TimerBase仅在11.3(15E216)上崩溃：SIGTRAP WebCore _ZN7WebCore9TimerBaseD2Ev，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我最近收到了Crash Report Tools的崩溃报告.这个崩溃是指UIWebView WebCore崩溃,我的应用程序只使用UIWebView,而我最近无法切换到WKWebview.下面是崩溃报告,我无法重现它.它发生在iPhone 6,7,8,X设备上,但只使用iOS 11.3版本(15E216).

这次崩溃有3个不同的崩溃堆栈.任何意见将是有益的.
