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

头文件：T02Vector.h

#ifndef __T02Vector_H__

编写：T02Vector.cpp

//如果不是Ref的子类，那不能用Vector，应该用std::vector

bool T02Vector::init()

{

    vm["aa"] = 10;

    // 访问，这种访问有副作用，如果bb节点不存在，它会创建一个bb节点

    Value& v = vm["bb"];

    v = 100;

    vm["bb"] = false;

#endif

    return true;

}

用到的about.xml如下：

<?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>

头文件：T04Label.h

#ifndef __T04Label_H__

#define __T04Label_H__

#include "T32.h"

class T04Label :public Layer{

public:

    CREATE_FUNC(T04Label);

    bool init();

};

#endif

编写：T04Label.cpp

#include "T04Label.h"

bool T04Label::init()

{

    Layer::init();

    {

        Label* label = Label::createWithCharMap("fonts/Labelatlas.png", 24, 32, '0');

        label->setString("12345");

        addChild(label);

        label->setPosition(winSize.width / 2, winSize.height / 2);

    }

#if 0

    Label* label = Label::createWithBMFont();

    Label* label = Label::createWithSystemFont("aaa", "Arial", 24);

    Label* label = Label::createWithTTF("");

#endif

    //Label* label = Label::createWithTexture()

    return true;

}

运行结果：
