I have GPU renderer view need to be initialized based on the frame of a subview. But I always get frame=zero no matter where I put the code.

I can't put it in viewDidLayoutSubviews, because it will be called multiple times, I don't know which one is the correct one.

viewDidAppear also not the correct answer.

And I found that first viewDidLayoutSubviews will be called after viewDidAppear. viewDidAppear should be called when its subviews are correctly layout?
