浏览数：45 / 时间：2015年06月11日

对于模拟器，其在终端的log文件位于：～/Library/Logs/CoreSimulator/C4B94BA6-EF08-4AD2-AE7D-1A3A2E2AC545/system.log

对于真机:

Here‘s another tip using the great libimobiledevice library http://www.libimobiledevice.org/, originally built to manage iOS devices on Linux.

This method shows you how you can view the log output (e.g. what you see in Xcode when running in debug mode) on any app, whether it‘s an AppStore build or an AdHoc build.

Some apps are more talkative than others - it all depends on how careful the developers were to remove log messages in release builds.

I find this most useful for debugging issues in release versions of our apps. If a user reports a sequence of actions causes a crash, you can try this out while watching the log from your app.

Here‘s how:

Grab the libimobiledevice binary for Mac OS X from my github account athttps://github.com/benvium/libimobiledevice-macosx/zipball/master
Follow the install instructions here:
https://github.com/benvium/libimobiledevice-macosx/blob/master/README.md

Connect your device, open up Terminal.app and type:

idevicesyslog

Up pops a real-time display of the device‘s system log.

With it being a console app, you can filter the log using unix commands, such as grep

For instance, see all log messages from a particular app:

idevicesyslog | grep myappname
