UIView. How do I place a subview behind it's parent superview

Question

I'm doing a bit of UIView wrangling and am stuck. It is straightforward changing the "z" order of sibling subviews. [mySuperview sendSubviewToBack:mySubview] places mySubview behind all it's siblings.

But how do I place a subview behind it's parent?

Thanks, Doug

Answer 1

You can't as far as I know. You'll have to remove it from the parent then add it to the parent's parent's subviews.

UIView *parent = view.superview;
[view removeFromSuperview];

/* Adjust frame to realign under parent view */

[parent.superview addSubview:view];

Answer 2

you can use the [self.view addSuview:(UIView *) belowSubview:(UIView *)] method to do this pretty easily

Answer 3

You may want to put both into a container view, so that you can properly place one behind the other without affecting a superview not really meant to hold arbitrary views (although that will probably work just fine).
