我有一张桌子，当选择正确答案时会显示图像，当我点击“backButton”移回“MainMenu”时，图像会停留在那里，但是当没有选择正确的答案时没有出现，它没有出现在现场过渡。
以下是代码：
local storyboard = require( "storyboard" )
local scene = storyboard.newScene()
storyboard.purgeOnSceneChange = true
display.setStatusBar(display.HiddenStatusBar)
local globalGameAnswer = 0
-- local functions go here
-----------------------------------
local function onButtonTouch(event)
if (event.phase == "ended") then
-- move to next scene
--storyboard.gotoScene('MainMenu')
end
end
local function backButtonTouch(event)
print( "button is touched" )
if(event.phase == "ended") then
storyboard.gotoScene('MainMenu')
end
end

答案 0 :(得分：3)
无法在组中添加本机对象，因此它们也会出现在其他电晕显示对象上方，因为它们不是OpenGL的一部分。
它们应该在scene：destroy（）函数中单独删除。
您可能知道我们在self.view＆amp;中添加的所有显示对象。自我视图被故事板清除，但由于无法将表添加到显示对象，您将无法清除。
使用这个： table.removeSelf（） 表=零
答案 1 :(得分：-1)
在CoronaSDK中，始终将所有内容添加到组（将组视为图层）非常重要
local group = display.newGroup()
local image = display.newImage("image.png")
group:insert(image)
执行此操作时，如果删除该组，则图像随附。同样重要的是要记住将新组添加到视图中。
local view = self.view
view:insert(group)
