我试图在我的应用程序中实现关卡样式页面。 我正在做一个降临节日历风格的应用程序，其中有一个日历页面（类似于级别选择页面），用户在其中选择一天并将您重定向到显示圣诞节消息的页面。
我使用我在这里找到的示例得到了一个类似的页面;http://www.christianpeeters.com/corona-sdk/level-selection-template-for-corona-sdk/
但是，当我在我的应用程序中实现这一点时，当我选择要打开的日期/级别时，一旦完成，图像不会过渡到完成的图像（绿色复选标记），并且它旁边的日期/级别仍然被锁定当它应该可用时。
我的代码可以在下面找到，帮助会很棒。谢谢！

尝试注释掉对removeAll的调用，不太可能需要它们： 清除和删除（卸载）场景主要是为了节省内存，因此清除和删除功能应仅用于很少重新访问但包含大量对象的场景。对于所有其他场景（经常访问的场景，或者没有很多对象的场景），它们不是必需的，并且可能会导致您可能遇到的细微错误。
请注意，storyboard.purgeOnScreenChange不存在，您可能打算storyboard.purgeOnSceneChange .但是拼写错误意味着设置保持错误，因此它不是您遇到的问题的一部分。但是，如果您修复了拼写错误，也要注释掉该行main.lua否则它将具有相同的效果。
因此，请注释掉与情节提要场景清除和删除功能有关的任何行，如果您觉得确实需要它们（因为默认的 Corona 行为不足），请在一个地方重新引入并测试场景之间的移动。
请注意，Corona 已移至 Composer 来管理场景，而不是故事板。话虽如此，您的关卡仍然被锁定，因为绘制关卡和设置侦听器的代码位于 createScene 函数中，而在您的情况下，该函数仅调用一次，因为如果您的场景尚未完全销毁，Corona 不会调用 createScene。
来自 Composer 中 scene：create（） 的文档（也适用于故事板）：
请注意，仅当场景的 视图不存在 — 也就是说，它将在第一次被称为 场景已加载。但是，作曲家试图将场景保留在内存中 假设您稍后会重新访问它，因此如果场景保留在 内存，场景：创建（）不会被调用。
因此，即使您正在修改全局级别表，当您回到calendar_scene时，也不会再次调用 createScene。您有 3 个选择：
-
您可以将绘图/设置侦听器代码移动到 willEnterScene函数，当您返回时将再次调用calendar_scene，这次使用更新的值（但这不是一个好主意 - 请记住删除 exitScene 中的显示对象、空侦听器等......
-
使用 storyboard.purgeOnSceneChange（而不是 purgeOnScreenChange，如Schollii 注意到）并将其设置为 true，这样场景将是当你离开它时被摧毁，这意味着createScene将被调用再次，当您从关卡选择回来时（更好，但同样，了解场景内存管理和相应的代码比使用快捷方式更重要，尽管有时这些快捷方式也有有效的用途）。
-
将代码迁移到 Composer API，同时，它可能是了解场景管理是个好主意。然后绘制您的级别选择，并在从特定级别返回时根据需要进行更新。
