Xcode:清除后查看控制台历史记录？

Question

如何查看 Xcode 控制台历史记录？我通过再次运行应用程序不小心清除了它，我想知道我是否可以找回被清除的内容。

Answer 1

Xcode 控制台输出记录在系统日志中。您可以使用 grep 从控制台搜索系统日志:

# view last 2000 lines of the system log
sudo tail -n2000 /private/var/log/system.log

# search system log for YourApp
sudo grep YourApp /private/var/log/system.log

# watch the system log as it's being written and filter for YourApp
sudo tail -f /private/var/log/system.log | grep YourApp
