我刚刚将React Native集成到现有的iOS应用中。当我进入初始化React Native的屏幕时，如果打包器没有运行，我会得到通常的红色屏幕，上面写着“No bundle URL present”。如果我点击底部的“Reload JS”按钮（或按Cmd + R）两次，我会遇到以下崩溃：
JSCExecutor.cpp:158] Check failed: *m_isDestroyed JSCExecutor::destroy() must be called before its destructor!
我正在使用this之类的代码初始化RN，创建RCTRootView。
如果打包机正在运行，一切正常。 Cmd + R可以很好地重新加载JS。如果我在JS中出现语法错误并重新加载以获取红色错误屏幕，然后我再次加载它，我会遇到同样的崩溃。
不确定它是否相关，但我也在崩溃消息之前的日志中看到此消息：
WARNING: Logging before InitGoogleLogging() is written to STDERR
崩溃的回溯如下：
