xcode动态修改build号

xcode根据version动态修改build号，如下图，按照步骤点击：New Run Script Phase

build script

然后在5处增加如下内容：

versionNumber=$(/usr/libexec/PlistBuddy -c "Print :CFBundleShortVersionString" "${INFOPLIST_FILE}")

buildNumber=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "${INFOPLIST_FILE}")

stable=`echo ${versionNumber} |awk -F"." '{print $1}'`

beta=`echo ${versionNumber} |awk -F"." '{print $2}'`

alpha=`echo ${versionNumber} |awk -F"." '{print $3}'`

buildNumber=$(($(($stable<<20))+$(($beta<<8))+$(($alpha<<4))))

/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
