iOS 在系统设置中展示Version, Build, Git等信息

   在设置中，展示自定义内容，如类似下图圈住区域内容

步骤:

1.在项目中添加Settings.bundle文件

Root.plist的Source code如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>PreferenceSpecifiers</key>
    <array>
        <dict>
            <key>Title</key>
            <string>Info</string>
            <key>Type</key>
            <string>PSGroupSpecifier</string>
        </dict>
        <dict>
            <key>DefaultValue</key>
            <string>1.2.3</string>
            <key>Key</key>
            <string>version_preference</string>
            <key>Title</key>
            <string>Version</string>
            <key>Type</key>
            <string>PSTitleValueSpecifier</string>
        </dict>
        <dict>
            <key>DefaultValue</key>
            <string>20170725.1</string>
            <key>Key</key>
            <string>build_preference</string>
            <key>Title</key>
            <string>Build</string>
            <key>Type</key>
            <string>PSTitleValueSpecifier</string>
        </dict>
        <dict>
            <key>DefaultValue</key>
            <string>4993065</string>
            <key>Key</key>
            <string>githash_preference</string>
            <key>Title</key>
            <string>Git</string>
            <key>Type</key>
            <string>PSTitleValueSpecifier</string>
        </dict>
    </array>
    <key>StringsTable</key>
    <string>Root</string>
</dict>
</plist>

3.编辑脚本，设置Settings.bundle的值

#获取Version
Version=$(/usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "${PROJECT_DIR}/${INFOPLIST_FILE}")
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:1:DefaultValue ${Version}" "${PROJECT_DIR}/${PROJECT_NAME}/Settings.bundle/Root.plist"

#获取Build
Build=$(/usr/libexec/PlistBuddy -c "Print CFBundleVersion" "${PROJECT_DIR}/${INFOPLIST_FILE}")
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:2:DefaultValue ${Build}" "${PROJECT_DIR}/${PROJECT_NAME}/Settings.bundle/Root.plist"

#获取Git当前git SHA1值
Git=`git rev-parse --short HEAD | awk ‘{print $1}‘`
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:3:DefaultValue ${Git}" "${PROJECT_DIR}/${PROJECT_NAME}/Settings.bundle/Root.plist"

4.配置项目脚本
   路径: Target -> 项目名字 -> Build Phases

1. 如果没有Run Script就在该区域左上角+来增加；
2. 将步骤3的脚本复制粘贴即可。

ok! 完成!
