关于CCTextFieldTTF虚拟键盘隐藏事件的捕捉

Cocos2d-x Lua
#1

在CCIMEDelegate.h有这样一段代码：
//////////////////////////////////////////////////////////////////////////
// keyboard show/hide notification
//////////////////////////////////////////////////////////////////////////
virtual void keyboardWillShow(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}
virtual void keyboardDidShow(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}
virtual void keyboardWillHide(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}
virtual void keyboardDidHide(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}

CCTextFieldTTF.h继承自CCIMEDelegate.h

我在CCTextFieldTTF.cpp中实现keyboardDidHide()和keyboardDidShow()，结果真机测试，给CCTextFieldTTF输入文字，键盘在隐藏显示切换的时候，压根没有调用keyboardDidShow()和keyboardDidHide()接口，新手求指教

是不是和
virtual void keyboardDidShow(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}
virtual void keyboardWillHide(CCIMEKeyboardNotificationInfo& info) {CC_UNUSED_PARAM(info);}
是 protected 有关？

谢谢回复，一开始也觉得和这两个有关，后来发现这两个接口在键盘隐藏显示切换时并没有被调用，此时调用的仍然是atachWithIMEa，于是问题也就解决了
