CCControlButton使用时发现的点击范围问题（只能在右下角点击按键）

比如以下代码

CCRect rect = CCRectMake(0,0,0,0);
CCRect rectInsets = CCRectMake(0,0,1,1);

CCScale9Sprite *backgroundButton = CCScale9Sprite::create("Icon.png",rect,rectInsets);
CCScale9Sprite *backgroundHighlightedButton = CCScale9Sprite::create("Icon.png",rect,rectInsets);
CCSize size=backgroundButton->getContentSize();
CCControlButton *m_button = CCControlButton::create(backgroundButton);
m_button->setBackgroundSpriteForState(backgroundHighlightedButton, CCControlStateHighlighted);
m_button->setPosition(200,200);
addChild(m_button, 1);

此代码编译过去后，会出现只能点击右下角的才能按键响应，经过查找学习发现在m_button中多加这句

m_button->setPreferredSize(CCSizeMake(size.width, size.height));

及可以正常点击按键范围，不过setPreferredSize在代码提示不出来，不知道大家的版本会不会提示出来咯
