对于app的发包，通常都是通过xcode进行Build-Archive-Export，生成最后的.ipa文件。 我们也可以通过在终端使用xcodebuild命令行来进行打包。以下是xcodebuild 可以使用的命令：

xcodebuild [-project <projectname>] [[-target <targetname>]...|-alltargets] [-configuration <configurationname>] [-arch <architecture>]... [-sdk [<sdkname>|<sdkpath>]] [-showBuildSettings] [<buildsetting>=<value>]... [<buildaction>]...
       xcodebuild [-project <projectname>] -scheme <schemeName> [-destination <destinationspecifier>]... [-configuration <configurationname>] [-arch <architecture>]... [-sdk [<sdkname>|<sdkpath>]] [-showBuildSettings] [<buildsetting>=<value>]... [<buildaction>]...
       xcodebuild -workspace <workspacename> -scheme <schemeName> [-destination <destinationspecifier>]... [-configuration <configurationname>] [-arch <architecture>]... [-sdk [<sdkname>|<sdkpath>]] [-showBuildSettings] [<buildsetting>=<value>]... [<buildaction>]...
       xcodebuild -version [-sdk [<sdkfullpath>|<sdkname>] [<infoitem>] ]
       xcodebuild -list [[-project <projectname>]|[-workspace <workspacename>]] [-json]
       xcodebuild -showsdks
       xcodebuild -exportArchive -archivePath <xcarchivepath> -exportPath <destinationpath> -exportOptionsPlist <plistpath>
       xcodebuild -exportLocalizations -localizationPath <path> -project <projectname> [-exportLanguage <targetlanguage>...]

最近闲来有空，对xcodebuild命令行进行了封装，试着做了一个自动化打包的工具。项目代码github地址：https://github.com/5566/QikPackage 供大家参考。
