模拟横屏场景下视图旋转后被裁切的问题与解决方法

Hey, I just worked through this exact issue!

If your container has width: 100% and height: 100% set, you have to apply the rotation transform directly to the container element itself using transform: [{ rotate: '90deg' }]—otherwise, your rotated view will get clipped unexpectedly.

Here's the context: I was trying to create a "simulated landscape" effect. I set up the view with appropriate dimensions (honestly, this part didn't matter much in the end) and then applied the rotation... only to find the content got chopped off. Once I moved the rotate transform to the full-size container instead of a child element, the clipping stopped entirely.

The key reason behind this is that when you rotate a child element inside a 100% width/height parent, the parent's bounds are tied to the original orientation. The rotated child ends up extending beyond those bounds, hence the clipping. Rotating the container itself lets the layout adjust to the rotated dimensions, so nothing gets cut off.
