在运行Corona SDK时出现黑屏（我正在使用Composer）。

当我保存并点击启动时，屏幕是黑色的，没有场景显示。

有人能找出问题并知道如何正确修复它吗？ 如果有人可以的话，我会很高兴。

谢谢。

这是我的 Main.lua-

display.setStatusBar(display.HiddenStatusBar)

local composer = require( "composer" )
local scene = composer.newScene()

-- your code goes here...

composer.gotoScene("menu")

这是我的 Menu.lua-

display.setStatusBar(display.HiddenStatusBar)

local composer = require( "composer" )

local scene = composer.newScene()

-- -----------------------------------------------------------------------------------------------------------------
-- All code outside of the listener functions will only be executed ONCE unless "composer.removeScene()" is called.
-- -----------------------------------------------------------------------------------------------------------------

-- local forward references should go here

-- -------------------------------------------------------------------------------

-- "scene:create()"
function scene:create( event )
   local sceneGroup = self.view

   local background = display.newImageRect( "background.png", 730, 400 )
   sceneGroup:insert( background )

end

-- "scene:show()"
function scene:show( event )

    local sceneGroup = self.view
    local phase = event.phase

    if ( phase == "will" ) then
        -- Called when the scene is still off screen (but is about to come on screen).
    elseif ( phase == "did" ) then
        -- Called when the scene is now on screen.
        -- Insert code here to make the scene come alive.
        -- Example: start timers, begin animation, play audio, etc.
        print("menu")
    end
end

-- "scene:hide()"
function scene:hide( event )

    local sceneGroup = self.view
    local phase = event.phase

    if ( phase == "will" ) then
        -- Called when the scene is on screen (but is about to go off screen).
        -- Insert code here to "pause" the scene.
        -- Example: stop timers, stop animation, stop audio, etc.
    elseif ( phase == "did" ) then
        -- Called immediately after scene goes off screen.
    end
end

-- "scene:destroy()"
function scene:destroy( event )

    local sceneGroup = self.view

    -- Called prior to the removal of scene's view ("sceneGroup").
    -- Insert code here to clean up the scene.
    -- Example: remove display objects, save state, etc.
end

-- -------------------------------------------------------------------------------

-- Listener setup
scene:addEventListener( "create", scene )
scene:addEventListener( "show", scene )
scene:addEventListener( "hide", scene )
scene:addEventListener( "destroy", scene )

-- -------------------------------------------------------------------------------

return scene
