Question

I have a UIScrollView with 2 subviews added to it. Now I wanna update the information displayed in one of the subviews. Is there a way to replace the existing subview with another view instead of addSubview?

Answer 1

Sure. There’s no single method that will perform an atomic swap, but several combinations like this will do what you want:

[scrollView insertSubview:newView aboveSubview:oldView];
[oldView removeFromSuperview];
