1.Cocos2dx 3.2中vector,ValueMap,Touch触摸时间的使用.iconv字符编解码

用到的about.xml例如以下：

<?xml version="1.0" encoding="UTF-8" ?>

<plist>

<dict>

<key>people1</key>

<string>许佳音工作室出品</string>

<key>people2</key>

<string>总监：许佳音</string>

<key>people3</key>

<string>程序：姜博</string>

<key>people4</key>

<string>美术：马俊</string>

<key>people5</key>

<string>改编：班级</string>

</dict>

</plist>
