【问题描述】：
我有一个相当基本的应用程序，您可以在其中导航菜单，然后访问视频和演示。
我的问题是，当您访问视频时，它会强制您先旋转屏幕。
通过使用 stage.scaleMode = Stage.ScaleMode.NO_SCALE，我能够让它在我的 iPhone 7 上完美运行，但我找不到针对 iPhone 8 或 10 进行扩展的方法。
我一直在尝试使用其他 StageScaleMode，它们非常适合菜单，但是当屏幕旋转时，比例变得非常不稳定。
它要么保持在原始纵横比内，要么在屏幕上变得非常大。
我尝试使用 stage.stageWidth 和 stage.stageHeight 来纠正这个问题，但它们永远不会返回正确的大小。
非常感谢您在解决轮换问题或使 NO_SCALE 工作方面的任何帮助。

【问题讨论】：
-
请分享您的相关代码。屏幕截图也可能会有所帮助。最有可能的是，您需要监听舞台调整大小事件（将在方向更改时触发），然后相应地调整视频大小。
-
老实说，我不确定什么是相关的。它是一个相当长的脚本，我目前没有任何似乎在做或不做的事情。也就是说，舞台调整大小似乎会有所帮助，但它似乎只在 NO_SCALE 模式下触发？对吗？
-
是的，舞台只有在设置为 NO_SCALE 时才会调整大小，否则不会调整大小，而是缩放。有关缩放选项的说明，请参见：stackoverflow.com/a/27786709/1457439
-
相关的是您播放视频的代码（导致屏幕旋转）。如果您使用 iPhone，大概这是一个 AIR 项目，因此无论舞台缩放模式如何，都可以在
stage.nativeWindow上监听调整大小 -
将代码添加到原始帖子中。我不是强迫它旋转，而是打开自动定向，然后等待用户旋转。我也会试试你的建议！感谢您的帮助！
