iphone崩溃日志分析工具symbolicatecrash用法

Symbolicatecrash是Xcode自带的一个分析工具,可以通过机器上的崩溃日志和应用的.dSYM文件定位发生崩溃的位置,把crash日志中的地址替换成代码相应位置。

使用效果:

使用方法:

1. 找到Symbolicatecrash文件

Xcode 4.3的之后

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/

Xcode 4.3之前

/Developer/Platforms/iPhoneOS.platform/Developer/Library/PrivateFrameworks/DTDeviceKit.framework/Versions/A/Resources/symbolicatecrash

(附:Mac系统显示隐藏文件

终端中输入以下命令

显示Mac隐藏文件的命令:defaults write com.apple.finder AppleShowAllFiles -bool true

隐藏Mac隐藏文件的命令:defaults write com.apple.finder AppleShowAllFiles -bool false

输入完回车,重启Finder:左上角的苹果标志-->强制退出-->Finder-->重新启动

2. Symbolicatecrash文件独立于Xcode,可以拷出来使用,附件中为Xcode4.5中的Symbolicatecrash文件

3. 命终端中输入命令,命令格式:Symbolicatecrash .crash .dSYM > aa.log

即:Symbolicatecrash + 崩溃日志 + APP对应的.dSYM文件 + > + 输出到的文件

 

4. 如果提示"DEVELOPER_DIR" is not defined

 

Xcode4.3之后 在终端中输入: export DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer

 

Xcode4.3之前 在终端中输入: export DEVELOPER_DIR=/Applications/Xcode.app

 

建议:每次打出版本后备份相应的.dSYM文件,对应版本崩溃后可根据此文件分析崩溃日志
