Cocos2d implements a menu control similar to CCMenu, which is a lua script control in the CCScrollView

It is impossible to add ccmenu to CCScrollView to achieve the sliding effect, because the trigger events of ccmenu are all captured in touchBegan, if you want to slide the CCScrollView to deselect this menu ,. therefore, we should write a control to simulate the ccmenu menu. After the button is pressed, if the button is not moved, the touch event is triggered and the touch event is canceled if the button is moved, implement the scroll Effect of buttons in CCScrollView...
