Programmatically send to front/back elements created from interface builder

In interface builder, there are layout options to send to back or send to front any elements such as UIButton, UIImage, UILabel etc...

Now, I would like to do the same at runtime, programmatically.

Is there an easy way to do that?

I do not want to create different views, just update the z-axis.

cocoa-touch
interface-builder
z-axis

There are a number of methods of UIView that allow you to modify the view hierarchy.

bringSubviewToFront:
sendSubviewToBack:
insertSubview:atIndex:
insertSubview:aboveSubview:
insertSubview:belowSubview:
exchangeSubviewAtIndex:withSubviewAtIndex:

Since your views are already inserted into your superview, you could easily call bringSubviewToFront: once for each view in whatever order you like.

You could use:

[self.view bringSubviewToFront:myButton];
