How to get container content size? [iOS]

[wgywgy]

I want get the container contentsize, but In the new arch(Enable fabric), RCTRootView's method: - (void)rootViewDidChangeIntrinsicSize:(RCTRootView *)rootView;
isn't call. Which replace method can at right time get IntrinsicSize?
Mannal get RCTFabricSurface's intrinsicSize also get zero value.

RN Version
0.68.1

Fristly, I calc contentsize on RCTRootComponentView's method - (void)mountChildComponentView:(UIView *)childComponentView index:(NSInteger)index and - (void)unmountChildComponentView:(UIView *)childComponentView index:(NSInteger)index. (Union the componentView bounces).
But sometime it's wrong.(In the case ScrollView)
Now I use js side onLayout event.nativeEvent.layout.width and height, and set native side contianer size by bridge method.
What's the recommand method?

which component is sized incorrectly ?
It's not sized incorrectly, my problem is I want know the container size.
The old arch tell by method - (void)rootViewDidChangeIntrinsicSize:(RCTRootView *)rootView.
The new arch does not call.
