如何实现输入文本TextFiledTTF

 

1 //获得可见区域的大小 2     Size visibleSize = Director::getInstance()->getVisibleSize(); 3      4     //使用一个默认要先呈现一段文字 5     TextFieldTTF *tf = TextFieldTTF::textFieldWithPlaceHolder("在这里输入", "宋体", 20); 6      7     tf->setPosition(visibleSize.width/2, visibleSize.height/2);//设置显示的位置 8  9     addChild(tf);10     11     //将输入文本与输入法链接12     //添加监听器13     auto listener = EventListenerTouchOneByOne::create();14     listener->onTouchBegan = [tf](Touch *t, Event *event){
   //闭包函数15         //先获取文本狂的边界区域.是否包括触摸点（Touch对象）16         if (tf->getBoundingBox().containsPoint(t->getLocation())) {17             tf->attachWithIME();//链接输入法18             19             log(">><><>");20         }else{21             tf->detachWithIME();22         }23         24         return false;25     };26     //添加监听器27     Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(listener, tf);
