[cocos2d-x ]点击空白隐藏键盘

cocos2dx edit编辑框点击后显示一个键盘，但是非常的不灵活，点return才能隐藏，如果我们需要点键盘外的背景，实现隐藏键盘，那就方便多了

方法：

1. 到EGLView.mm下注释2个reurn，这样就能保证显示软键盘的时候，还能将点击事件传送到最底层

[cpp]
// Pass the touches to the superview
#pragma mark EAGLView - Touch Delegate
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (isKeyboardShown_)
    {
        [self handleTouchesAfterKeyboardShow];

        //WARNING:commented by Teng.点触背景隐藏软键盘
        //return;
    }

    int ids[IOS_MAX_TOUCHES_COUNT] = {0};
    float xs[IOS_MAX_TOUCHES_COUNT] = {0.0f};
    float ys[IOS_MAX_TOUCHES_COUNT] = {0.0f};

    int i = 0;
    for (UITouch *touch in touches) {
        ids[i] = (int)touch;
        xs[i] = [touch locationInView: [touch view]].x * view.contentScaleFactor;;
        ys[i] = [touch locationInView: [touch view]].y * view.contentScaleFactor;;
        ++i;
    }
    cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesBegin(i, ids, xs, ys);
}

// Pass the touches to the superview
#pragma mark EAGLView - Touch Delegate
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (isKeyboardShown_)
    {
        [self handleTouchesAfterKeyboardShow];

        //WARNING:commented by Teng.点触背景隐藏软键盘
        //return;
    }

    int ids[IOS_MAX_TOUCHES_COUNT] = {0};
    float xs[IOS_MAX_TOUCHES_COUNT] = {0.0f};
    float ys[IOS_MAX_TOUCHES_COUNT] = {0.0f};

    int i = 0;
    for (UITouch *touch in touches) {
        ids[i] = (int)touch;
        xs[i] = [touch locationInView: [touch view]].x * view.contentScaleFactor;;
        ys[i] = [touch locationInView: [touch view]].y * view.contentScaleFactor;;
        ++i;
    }
    cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesBegin(i, ids, xs, ys);
}

[cpp]
(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (isKeyboardShown_)
    {
        <STRONG><SPAN style="COLOR: #ff0000">//WARNING:commented by Teng.点触背景隐藏软键盘</SPAN>
        //return;</STRONG>
    }

    int ids[IOS_MAX_TOUCHES_COUNT] = {0};
    float xs[IOS_MAX_TOUCHES_COUNT] = {0.0f};
    float ys[IOS_MAX_TOUCHES_COUNT] = {0.0f};

    int i = 0;
    for (UITouch *touch in touches) {
        ids[i] = (int)touch;
        xs[i] = [touch locationInView: [touch view]].x * view.contentScaleFactor;;
        ys[i] = [touch locationInView: [touch view]].y * view.contentScaleFactor;;
        ++i;
    }
    cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesEnd(i, ids, xs, ys);
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    if (isKeyboardShown_)
    {
        //WARNING:commented by Teng.点触背景隐藏软键盘
        //return;
    }

    int ids[IOS_MAX_TOUCHES_COUNT] = {0};
    float xs[IOS_MAX_TOUCHES_COUNT] = {0.0f};
    float ys[IOS_MAX_TOUCHES_COUNT] = {0.0f};

    int i = 0;
    for (UITouch *touch in touches) {
        ids[i] = (int)touch;
        xs[i] = [touch locationInView: [touch view]].x * view.contentScaleFactor;;
        ys[i] = [touch locationInView: [touch view]].y * view.contentScaleFactor;;
        ++i;
    }
    cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesEnd(i, ids, xs, ys);
}

2.最底层的layer类中添加处理：显示和隐藏键盘就OK了

[cpp]
void ccTouchEnded(cocos2d::CCTouch *pTouch, cocos2d::CCEvent *pEvent)
{
    do
    {
        if (mTelNumber) {
            CCPoint endPos = pTouch->getLocation();

            float delta = 5.f;
            if (::abs(mBeginPos.x - endPos.x) > delta
                || ::abs(mBeginPos.y - endPos.y) > delta) {
                    break;
            }

            // 看编辑框是否被点中
            CCPoint point = mTelNumber->getParent()->convertTouchToNodeSpaceAR(pTouch);

            // 锚点(0.f, 0.5f)
            //int x = mTextField->getParent()->getPosition().x;
            //int y = mTextField->getParent()->getPosition().y;
      &n
