self remove listener from invoked function

Getting Started Newbie Questions
#1

How would I make the invoked function self remove the listener that was created?     

    self:addEventListener(“touch”, function(event)

            if event.phase == “began” then

                robusto.goToFrame(“main”, “fadeIn”)

                

                – NEED CODE TO REMOVE THE LISTENER HERE

            end

        end)

#2

Can’t afaik

#3

If you add an anonymous function as your event listener, you’ll never be able to remove it, since you have no reference to it.  But if you define the function first, then you should be able to.

To answer my own question… and thanks to a post by Ludicrous software, you can apply what they did to an invoked function like below - it seems to work out well.

      

screen.images.background:addEventListener(“touch”, function(event)

            if event.phase == “began” then

                robusto.goToFrame(“main”, “fadeIn”)

                

                screen.images.background._functionListeners = nil – remove all of the listeners

                screen.images.background._tableListeners = nil     – remove all of the listeners

            end

        end)

Knew about that but it’s not good practice cause if corona has a listener added to it foursome reason it removes it also which would cause other problems
