CCTextFieldTTF是一个简单的封装，用起来不是那么便利，在cocos2dx的extension里，对输入框有更加简单使用的类，那就是CCEditBox

上代码先：

bool EditBox01::init(){    //    // 1. super init first    if ( !MenuLayer::init() )    {        return false;    }        CCSize size = __winSize;                m_pEditName = CCEditBox::create(CCSizeMake(size.width-100, 60), CCScale9Sprite::create("extensions/green_edit.png"));    m_pEditName->setPosition(ccp(size.width/2, size.height/2));    addChild(m_pEditName);    m_pEditName->setFontSize(25);    m_pEditName->setFontColor(ccRED);    m_pEditName->setPlaceHolder("Name:");    m_pEditName->setPlaceholderFontColor(ccWHITE);    m_pEditName->setMaxLength(8);    m_pEditName->setReturnType(kKeyboardReturnTypeDone);        m_pEditPassword = CCEditBox::create(CCSizeMake(size.width-100, 60), CCScale9Sprite::create("extensions/orange_edit.png"));    m_pEditPassword->setPosition(ccp(size.width/2, size.height/2-80));    addChild(m_pEditPassword);    m_pEditPassword->setFontColor(ccGREEN);    m_pEditPassword->setPlaceHolder("Password:");    m_pEditPassword->setMaxLength(6);    m_pEditPassword->setInputFlag(kEditBoxInputFlagPassword);    m_pEditPassword->setInputMode(kEditBoxInputModeSingleLine);        m_pEditEmail = CCEditBox::create(CCSizeMake(size.width-100, 60), CCScale9Sprite::create("extensions/yellow_edit.png"));    m_pEditEmail->setPosition(ccp(size.width/2, size.height/2-80-80));    m_pEditEmail->setPlaceHolder("Email:");    m_pEditEmail->setInputMode(kEditBoxInputModeEmailAddr);    addChild(m_pEditEmail);        return true;}

三个控件对应上面的代码，当鼠标点击某一个控件时，自动弹出虚拟键盘，并临时调整控件位置，如果需要的话
