问题描述

旋转后的orientationchange火灾已经完成。我怎么能在OS启动综合窗口旋转之前触发一个事件？

the orientationchange fires after the rotation has been completed. how can i fire a event before the os starts the integrated window rotation ?

编辑：例如。淡出轮换开始前元素

edit: eg. to fade out elements before rotation starts

推荐答案

您可以检测设备precise旋转，所以当你看到它旋转到precise点，屏幕旋转时之前，可以触发它

you can detect the devices precise rotation so when you see it rotates to a precise point, before the screen rotates, you can trigger it.

这可能有一定的误报强硬。
