textField->runAction(CCMoveTo::create(0.225f,  Vec2(screenSize.width / 2.0f, screenSize.height / 2.0f +textField->getContentSize().height / 2.0f)));

_displayValueLabel->setString(String::createWithFormat("attach with IME")->getCString());

textField->setMaxLengthEnabled(true); //设置允许最大数目限制

textField->setMaxLength(3);//设置最大允许数目为3

textField->setPasswordEnabled(true);//设置可设置为密码模式

textField->setPasswordStyleText("*");//设置密码的遮挡字符为*

textField->setPlaceHolder("input text here"); //设置占位符
        textField->setPlaceHolderColor(Color4B::GREEN);
//设置占位符颜色

textField->setTextColor(Color4B::RED);


//如果要设置自动换行

textField->ignoreContentAdaptWithSize(false);//(必须要有的代码)此处为false,如果为true, 则不管setContentSize为何大小,该控件只使用getVirtualRendererSize()这个函数返回的Size大小

((Label*)(textField->getVirtualRenderer()))->setLineBreakWithoutSpace(true);///(必须要走的最关键代码)

textField->setContentSize(Size(240, 170));//(必须要有的代码)

textField->setTextHorizontalAlignment(TextHAlignment::LEFT);//设置文字在水平方向的对齐方式
textField->setTextVerticalAlignment(TextVAlignment::TOP);//设置文字在垂直方向的对齐方式

//对齐方式setTextHorizontalAlignment我们可以这么理解,LEFT就是整行文字靠着左边对齐,RIGHT就是整行文字靠着右边对齐,

//对齐方式setTextVerticalAlignment我们可以这么理解,TOP就是你整篇文字靠着顶部对齐,反之BOTTOM就是整篇文字靠着底部对齐

textField->getVirtualRendererSize();//可以获取它的实际大小

((Label*)(textField->getVirtualRenderer()))->setLineBreakWithoutSpace(true);//为true,内容超过width,会自动换行
