	addChild(tf);
	auto listener = EventListenerTouchOneByOne::create();
	listener->onTouchBegan = [tf](Touch *t,Event *event){
		if(tf->getBoundingBox().containsPoint(t->getLocation()))
		{
			tf->attachWithIME();
		}else
		{
			tf->detachWithIME();
		}

		return false;

	Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraPHPriority(listener,tf);
