xcodebuild和xcrun自动化编译ipa包

打包过程

xcodebuild负责将工程源文件编译成xxx.app

xcrun负责给xxx.app(签名并)打包成xxx.ipa

第一步清理:xcodebuild clean

第二步编译:xcodebuild

第三步打包:xcrun -sdk iphoneos PackageApplication -v path/To/xxx.app -o xxx.ipa

bash shell入门：

使用getopts命令使用
:表示有参数需要值

#!/bin/bash
while getopts h:ms option
do
case "$option" in
h)
echo "option:h, value $OPTARG"
echo "next arg index:$OPTIND";;
m)
echo "option:m"
echo "next arg index:$OPTIND";;
s)
echo "option:s"
echo "next arg index:$OPTIND";;
\?)
echo "Usage: args [-h n] [-m] [-s]"
echo "-h means hours"
echo "-m means minutes"
echo "-s means seconds"
exit 1;;
esac
done

在使用getopts命令的时候，shell会自动产生两个变量OPTIND和OPTARG。OPTIND初始值为1，其含义是下一个待处理的参数的索引。只要存在，getopts命令返回true，所以一般getopts命令使用while循环；
在while循环中判断

if getopts $param_pattern optname ;then
echo  "Error argument value for option $tmp_optname"
exit 2
fi

可以判断参数值是否是下个参数名称，如果是，就退出

#判断输入参数是否大与0
if [ $# -lt 1 ];then
echo "Error! Should enter the root directory of xcode project after the ipa-build command."
exit 2
fi

#判断第一个参数是否是目录
if [ ! -d $1 ];then
echo "Error! The first param must be a directory."
exit 2
fi

xcodebuild使用

sage: xcodebuild [-project <projectname>] [[-target <targetname>]...|-alltargets] [-configuration <configurationname>] [-arch <architecture>]... [-sdk [<sdkname>|<sdkpath>]] [<buildsetting>=<value>]... [<buildaction>]...
xcodebuild -workspace <workspacename> -scheme <schemeName> [-configuration <configurationname>] [-arch <architecture>]... [-sdk [<sdkname>|<sdkpath>]] [<buildsetting>=<value>]... [<buildaction>]...
xcodebuild -version [-sdk [<sdkfullpath>|<sdkname>] [<infoitem>] ]
xcodebuild -list [[-project <projectname>]|[-workspace <workspacename>]]
xcodebuild -showsdks
Options:
-usage                print full usage
-verbose              provide additional status output
-project NAME         build the project NAME
-target NAME          build the target NAME
-alltargets           build all targets
-workspace NAME       build the workspace NAME
-scheme NAME          build the scheme NAME
-configuration NAME   use the build configuration NAME for building each target
-xcconfig PATH        apply the build settings defined in the file at PATH as overrides
-arch ARCH            build each target for the architecture ARCH; this will override architectures defined in the project
-sdk SDK              use SDK as the name or path of the base SDK when building the project
-parallelizeTargets   build independent targets in parallel
-jobs NUMBER          specify the maximum number of concurrent build operations
-showsdks             display a compact list of the installed SDKs
-list                 lists the targets and configurations in a project, or the schemes in a workspace
-find BINARY          display the full path to BINARY in the provided SDK
-version              display the version of Xcode; with -sdk will display info about one or all installed SDKs
