花了几个小时试图在这里解决一个故事板问题。我已经修剪了一个复制它的示例项目。

问题：

  • 从场景 1 到场景 2，然后回到场景 1，然后在场景中切换几次后，我得到以下信息：
  • 进入场景时，日志显示多个 enterScene/exitScene 被触发
  • 似乎可能正在注册多个背景触摸侦听器，但是我试图在 exitScene 函数中删除这些
  • 我在试用版：2011.704 (2011.12.8)

输出

<code>
-- Click on background to go back to screen_example1

storyboard.gotoScene( screen_example1)
screen_example1: enterScene

storyboard.gotoScene( screen_example1)
screen_example1: exitScene
screen_example1: enterScene

storyboard.gotoScene( screen_example1)
screen_example1: exitScene
screen_example1: enterScene

storyboard.gotoScene( screen_example1)
screen_example1: exitScene
screen_example1: enterScene

.

etc
</code>

代码：三个文件：主文件和两个场景文件：

主程序.lua

<code>
display.setStatusBar( display.HiddenStatusBar )
local storyboard = require "storyboard"
storyboard.gotoScene( "screen_example1" )
</code>

screen_example1.lua

<code>
local storyboard =  require( "storyboard" )
local scene = storyboard.newScene()

local function onScreenTouch( event )
    if event.phase == "began" then
        print("")
        storyboard.gotoScene( "scene_towerView")  
    end
end


function scene:createScene( event )
    print ("screen_example1 - createScene")
    local image = display.newImage( "bg.jpg" )
    scene.view:insert( image )
end

function scene:enterScene( event )
    print ("screen_example1: enterScene")
    scene.view:addEventListener( "touch", onScreenTouch )
end

function scene:exitScene( event )
    print ("screen_example1: exitScene")
    scene.view:removeEventListener("touch", onScreenTouch)
end

-- Scene Listeners
scene:addEventListener( "createScene", scene )
scene:addEventListener( "enterScene", scene )
scene:addEventListener( "exitScene", scene )
scene:addEventListener( "destroyScene", scene )


return scene
</code>

scene_towerView.lua

<code>
local storyboard =  require( "storyboard" )
local scene = storyboard.newScene()

local function onScreenTouch( event )
    if event.phase == "began" then
        print("")
        print("storyboard.gotoScene( screen_example1)")
        storyboard.gotoScene( "screen_example1")
    end
end

-- Scene Handlers

function scene:createScene( event )
    print ("TowerScene - createScene")

    -- -- Background Image
    local image = display.newImage( "bg2.jpg" )
    scene.view:insert( image )
end

function scene:enterScene( event )
    print ("TowerScene - enterScene")
    scene.view:addEventListener( "touch", onScreenTouch )
end

-- Scene Listeners
scene:addEventListener( "createScene", scene )
scene:addEventListener( "enterScene", scene )
scene:addEventListener( "exitScene", scene )
scene:addEventListener( "destroyScene", scene )

return scene

您是否尝试在触摸事件代码的末尾添加“return true”？这让我困扰了最长时间。
