问题
Now I have a CCLayer of gameplay, where there are a few buttons. And I want to pop up a dialog layer, where there are also a few buttons. How can I deactivate the background buttons and only make the foreground buttons activated?
回答1:
Use CCMenuItem setIsEnabled method to disable button.

What about a lot of buttons on gameplay? Disable every button looks like not the best solution... Is it possible to disactivate all buttons in one fell swoop as topic starter requested?
