```
#include"cocos2d.h"
#include"cocos-ext.h"
USING_NS_CC;
USING_NS_CC_EXT;
using namespace cocos2d::ui;
```
注：因为版本更迭，editbox原本是在cocos-ext中，现行版本则更换到了ui中，所以以上头文件和名空间根据自己的版本选择（新版本使用ext也可正常使用，原因见下图，但不建议）
如下，使用EditBox的类要继承ui::EditBoxDelegate
（可使用using namespace cocos2d::ui以省略ui::,本人项目因为需要使用到ext所以为了避免混淆添加了ui::）
class HomeEditBox : public Node,ui::EditBoxDelegate
在类中要声明并实现以下函数：
virtual void editBoxEditingDidBegin(ui::EditBox* editBox);
virtual void editBoxEditingDidEnd(ui::EditBox* editBox);
virtual void editBoxTextChanged(ui::EditBox* editBox,conststd::string& text);//编辑框内容改变
virtual void editBoxReturn(ui::EditBox* editBox);//点击键盘回车/确认按钮
m_editBox=ui::EditBox::create(Size(170,80),ui::Scale9Sprite::create("editBoxBg.png"));
//size为输入框大小，第二个参数为输入框背景，使用Scale9Sprite
m_editBox->setFontSize(40);//输入内容字体大小
m_editBox->setFontColor(Color3B::Black);//输入内容字体颜色
m_editBox->setPlaceHolder("Please enter a number:");//输入框提示内容，当输入内容为空时显示，如果内容不为空则不显示
m_editBox->setPlaceholderFontColor(Color3B::GRAY);//提示内容字体颜色
m_editBox->setMaxLength(5);//输入内容长度
m_editBox->setInputMode(ui::EditBox::InputMode::DECIMAL);//输入键盘模式
