电晕中的按钮移除 [英] Button removal in Corona

问题描述

我正在尝试在我正在开发的应用程序中嵌套页面等，并通过按下按钮来实现.但是，作为小部件，它会随身携带，因此必须使用display.remove()或:removeSelf将其删除.我试图使这些按钮在被按下并加载下一页时从视图中删除/删除它们自己，但是当我这样做时，它要么不起作用，要么抛出运行时错误.有建议吗?

I'm trying to nest pages and such with button presses in an app I am working on. However, as a widget, it carries over and such and must be removed using display.remove() or :removeSelf. I'm trying to make these buttons delete/remove themselves from the view as they are pressed and the next page is loaded, but when I do this it either does not work, or throws a runtime error. Suggestions?

这是我当前正在使用的，尽管单击后它使按钮永久消失了. `

This is what I am currently using, although it leaves the button gone permanently after click. `

local onButtonEvent = function (event )
    if event.phase == "release" then
        display.remove( myButton )
        myButton = nil
        display.remove( buttonGroup )
        buttonGroup = nil
        storyboard.gotoScene( "shape" )
    end
end

推荐答案

这是另一种方法.为什么不设置

Here's another way. Why don't you set

myButton.isVisible = false

在您的onButtonEvent函数中

.

inside your onButtonEvent function.

我从未使用过StoryBoard，但是我很确定当您进入场景时会触发一个事件(我认为是"willEnterScene").

And I've never used StoryBoard, but I'm pretty sure there is a event fired ("willEnterScene" I think) when you enter the scene.

因此您可以在那里设置mybutton.isVisible = true

So you can set mybutton.isVisible = true there
