1.Cocos2dx 3.2中vector,ValueMap,Touch触摸时间的使用.iconv字

头文件：T02Vector.h

#ifndef __T02Vector_H__

#define __T02Vector_H__

#include "T32.h"

class T02Vector : public Layer

{

public:

CREATE_FUNC(T02Vector);

//Cocos2dx3.2以后使用Vector代替了CCArray

//增加元素

_arr.pushBack(sprite);

//遍历

}

{

}

//从后往前遍历

}

//删除

return true;

}

头文件：T03Map.h

#ifndef __T03Map_H__

#define __T03Map_H__

#include "T32.h"

class T03Map : public Layer{

public:

};

#endif

编写：T03Map.cpp

#include "T03Map.h"

/*

ValueMap是用来代替cocos2d.x的CCDictionary

*/

bool T03Map::init()

{

Layer::init();

//内容的加载

ValueMap& vm = FileUtils::getInstance()->getValueMapFromFile("about.xml");

//CCDictionary* dict = CCDictionary::createWithContentsOfFile("about.xml");

//const CCString* x = dict->valueForKey("x");

//x->intValue();

//查找

auto it = vm.find("aaa");

if (it == vm.end())

{

CCLog("can not find aaa");

}

it = vm."people3");

it->first; //key:的类型是std::string

it->second; //value:的类型是Value，相对cocos3.2.3的CCString

"key is %s,value is %s",it->first.c_str(),it->second.asString().c_str());

"............................end");

vm["中文"] = "bbb";

"........start walk over");

//遍历

for (auto it = vm.begin(); it != vm.end();++it)

{

c_str());

}

"..........................end");

writeToFile(vm,"new.xml");

#if 0

// C++11

for (auto it : vm)

{

it.first;

it.second;

}

// 插入

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

#define __T04Label_H__

#include T04Label :public T04Label);

bool

编写：T04Label.cpp

bool T04Label::init();

{

Label* label = Label::createWithCharMap("fonts/Labelatlas.png",24,32,21); font-family:新宋体; font-size:9.5pt">'0');

label->setString("12345");

addChild(label);

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

}

#if 0

createWithBMFont();

createWithSystemFont("aaa",21); font-family:新宋体; font-size:9.5pt">"Arial",24);

createWithTTF("");

#endif

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

return true;

}

运行结果：
