我正在逆向工程
Xcode,我想知道是否有办法启用调试日志.我猜Xcode可能有一些隐藏的偏好,是吗？
解决方法
是的,您可以在Xcode中启用大量隐藏日志.以下列出了可以调整日志级别的所有方面.获取此列表

有三个日志级别
>关键(默认)
>标准
>详细
要更改日志级别,请将LogLevel附加到方面名称并将其写入Xcode的首选项.例如,要获取有关SDK加载的详细日志,请键入以下命令：
defaults write com.apple.dt.xcode DVTSDKLogLevel -int 3 && killall -u $USER cfprefsd
要一次更改所有日志级别,请使用DVTDefaultLogLevel首选项.但是你可能不想这样做,因为它会很快变得过于冗长.
如果您不希望永久存储用户默认值,则可以从终端运行Xcode并将用户默认值作为参数传递：
/Applications/Xcode.app/Contents/MacOS/Xcode -DVTSDKLogLevel 3
