我用的是cocos2dx2.2版本，textfield的settouchsize 只是一个样式，点击输入框的时候只有点击到文字才能进行输入，当文本长度很短视，体验感差的不行
直接说方法吧，废话也没人看、、
为要点击的区域增加 imageview
exchangeTextBg = dynamic_cast<ImageView *>(ui->getWidgetByName("reward_exchange_bg_0"));
exchangeTextBg->setTouchEnabled(true);
exchangeTextBg->addTouchEventListener(this,toucheventselector(RewardExchangePanel::onTouchExhcangeTextBg));这个是textfield
exchangeTextField = dynamic_cast<TextField *>(ui->getWidgetByName("reward_exchange_text"));
头文件
void onTouchExhcangeTextBg(CCObject *target,TouchEventType type);
区域触摸函数，让textfield直接调用attactWithIME()函数就可以了
void RewardExchangePanel::onTouchExhcangeTextBg(CCObject *target,TouchEventType type)
{
if( type != TouchEventType::TOUCH_EVENT_ENDED) return;
exchangeTextField->attachWithIME();
exchangeTextField->setColor(ccc3(70,155,87));
}以后再也不用纠结输入框点击区域范围太小的问题了，哈哈 原文链接：https://www.f2er.com/cocos2dx/345036.html
