本机console.debug没有使用log-ios显示日志

Question

升级现有项目以响应本机v 0.48.3后,当我在模拟器上运行应用程序时,console.debug不会列出日志.它曾经工作,直到我升级使用react-native upgrade选项.

任何使用查看日志的建议react-native log-ios.如果我运行远程调试器,我能够在Chrome控制台上查看日志.

React native version: 0.48.3
iOS = macOS Sierra 10.12.6.

react-native log-ios显示

我刚刚遇到这个问题。日志记录在开发模式下工作正常，突然，react-native log-ios 的控制台窗口中没有 console.log 输出到 stdout。但是，我可以在 IOS 模拟器中的“调试”>“打开系统日志”下看到消息。
