推荐答案

您可以使用/修改此内容:(这就是Rob Miracle所说的)

You can use/modify this: (It's what Rob Miracle says)

local holding = false
local function enterFrameListener()
    if holding then
        -- Holding button
        -- Code here
        -- Code here
        -- Code here
    else
        -- Not holding
        -- Code here
        -- Code here
        -- Code here
    end
end

local function touchHandler( event )
    if event.phase == "began" then
        display.getCurrentStage():setFocus( event.target )
        event.target.isFocus = true
        Runtime:addEventListener( "enterFrame", enterFrameListener )
        holding = true
    elseif event.target.isFocus then
        if event.phase == "moved" then
        elseif event.phase == "ended" then
            holding = false
            Runtime:removeEventListener( "enterFrame", enterFrameListener )
            display.getCurrentStage():setFocus( nil )
            event.target.isFocus = false
        end
    end
    return true
end

我相信touchHandler函数是什么^^

I believe its obvious what touchHandler function is ^^
