Not sure if it is a bug since the soft key is designed for hiding the keyboard. Only iPad has that key on its soft keyboard, different from return key, which is handled automatically.

Thanks. #505 is created for this

It's been quite a while so I am guessing that it is intended behavior.

I ran across this small issue and would like to share with the community how to handle this situation. Inherit from CCIMEDelegate and override: void keyboardDidHide(cocos2d::CCIMEKeyboardNotificationInfo& info);

From there you can manually detach the IME: inputField->detachWithIME();

thank u for ur solution.

Thank you indeed - I made some changes to CCTextFieldTTF based on your info and it worked like a charm.

here are the code changes.

in CCTextFieldTTF.h

class CC_DLL CCTextFieldDelegate
{
public:

    [...]

    virtual bool onDraw(CCTextFieldTTF * sender)
    {
        CC_UNUSED_PARAM(sender);
        return false;
    }

    //line additions
    virtual void    onTextFieldDidAttachIME( CCTextFieldTTF * sender ) {  CC_UNUSED_PARAM(sender); } // added this to deal with iPad hide key - line addition
    virtual void    onTextFieldDidDetachIME( CCTextFieldTTF * sender ) {  CC_UNUSED_PARAM(sender); } // added this to deal with iPad hide key - line addition
};

class CC_DLL CCTextFieldTTF : public CCLabelTTF, public CCIMEDelegate
{
public:
    CCTextFieldTTF();
    virtual ~CCTextFieldTTF();

    [...]

    // cocos2d-x fix (addition)
    void keyboardDidHide(cocos2d::CCIMEKeyboardNotificationInfo& info);                     // needed to handle iPad soft keyboard "hide" key - line addition
